5 Reasons Why You Need Sunglasses

The sun is dangerous, and it can damage your eyes. In fact, ultraviolet rays can cause cataracts, macular degeneration, pterygium, and glaucoma. Sunglasses can prevent these issues and keep your eyes safe during the healing process.

UV Rays Can Cause Cataracts

According to new research, chronic exposure to UV rays may increase your risk of developing cataracts. Cataracts are cloudy spots on the eye lens, progressively deteriorating over time, and can lead to total blindness if left untreated. Cataracts typically develop in older people and are caused by the damage that UV rays cause to the skin.

Scientists are not exactly sure how UV light affects lens cells, but they do know that UV light can trigger damage to proteins inside the lens. This damage is linked to oxidative stress, which damages lens proteins. The resulting accumulation of damaged proteins leads to the development of cataracts.

Macular Degeneration

The sun’s ultraviolet rays cause damage to the retina and eye lenses. Wearing sunglasses that block 100% of these rays will protect your eyes and keep them healthy. They should also be polarized to reduce glare. Using a hat and sunglasses at the same time during high exposure to the sun will also help protect your eyes.

If you’re prone to macular degeneration, you may need to wear special sunglasses to protect your eyes. The lenses are made of a particular type of plastic called polycarbonate, which makes them lightweight and thin. They’re also designed to be comfortable and stylish, as they fit over prescription eyeglasses. These glasses can also be tinted to block out blue light and improve your vision.

Pterygium

Pterygium is a common skin condition caused by exposure to ultraviolet light. People who spend a lot of time outside in hot weather are particularly susceptible to the condition. It’s also more common in men than in women and is often linked to exposure to the sun during childhood and adolescence. Pterygium is often caused by a combination of factors.

If you suspect that you may have a pterygium, visit your eye care provider. They can perform an examination and prescribe steroid eye drops or artificial tears to relieve your discomfort. In some cases, surgery may be needed to remove the pterygium completely. However, this is only an option if it becomes too severe or impedes your vision.

Glaucoma

People with glaucoma are especially sensitive to light. Their symptoms can be worsened by bright lights and other bright surfaces, as well as by the medications they take to treat glaucoma. The condition can also be made worse by UV rays, damaging the surface and inner structures of the eyes. This damage can lead to cataracts and macular degeneration. It can also cause a person’s vision to become blurry, so wearing sunglasses is essential.

To protect your eyes from ultraviolet rays, you should wear sunglasses that are wrapped around your face. These are especially effective for driving, as they reduce glare and provide extra protection. You can also buy photochromic sunglasses that darken in bright light and lighten in low light. These glasses can help slow the progression of glaucoma and relieve discomfort caused by light sensitivity.

Pterygium Causes Pink Eye

Pterygium is a common eye condition caused by prolonged exposure to ultraviolet light. This disease is more common in desert and tropical regions. It’s also common among people who work outdoors. The most effective way to protect your eyes from this ailment is to wear sunglasses that offer 100% UV protection. You should also choose wrap-around styles as they offer better protection than those with smaller frames.

The exact cause of pterygium is unknown, but researchers believe that ultraviolet light and exposure to dusty or sandy conditions may play a role. People who spend a lot of time outdoors are at higher risk, as is anyone who doesn’t wear sunglasses. It’s also thought that exposure to UV radiation may affect certain genes. And age is also a risk factor for developing pterygium, with up to 12% of men over 60 in Australia suffering from it. Various factors are likely to be responsible for this condition, so a visit to an eye doctor is necessary to determine if you are at risk.

Macular Degeneration Causes Vision Loss

Macular degeneration (AMD) is a condition that causes vision loss and can be treated. There are several different types of treatments, including medication and surgical procedures. The goal is to slow the progression of the disease and improve vision. Patients may require several treatments to see the best results. Treatment can include proper eye care and a healthy diet.

Age is the main risk factor for developing AMD. This condition usually appears after age 50, and the incidence rises dramatically after age 75. Other risk factors include high blood pressure and smoking. Those with a family history of macular degeneration are also at greater risk. Exposure to too much light can also increase the risk of developing the condition. In the early stages of AMD, symptoms may not be noticeable, and patients may experience vision loss in one or both eyes.

All About Lasik Surgery

Before you consider getting LASIK surgery, it is important to understand some basic information about this procedure. This includes the Requirements, Procedures, Cost, and Side Effects. Read on to learn more about this revolutionary procedure. This surgical procedure is a great way to correct astigmatism, hyperopia, and other vision conditions. It is performed by using lasers to reshape the cornea.

Requirements for LASIK Surgery

Before undergoing LASIK surgery, you should make sure you’re in a good general eye health condition. In addition, you should be free of any eye diseases, infections, or injuries. You also need to be free of autoimmune diseases and medications that can slow down healing.

LASIK surgery permanently changes the shape of the cornea, which improves vision and reduces the need for contact lenses and glasses. Clear vision is achieved by the correct bending of light rays, allowing images to focus on the retina. In contrast, people with refractive errors experience blurry vision due to a mismatch between the length and shape of the cornea.

LASIK surgery is suitable for healthy individuals who are at least 30 years old. Pregnant women are not candidates for surgery because their eye prescription is unstable during pregnancy. It is also important to avoid contact lenses for two to four weeks prior to the surgery. Patients with myopia, hyperopia, or astigmatism up to 5.5 diopters can undergo LASIK.

Procedures Involved

The Lasik procedure involves a laser reshaping the corneal tissue. This procedure is done on an outpatient basis and takes between 20 minutes and an hour per eye. Patients are given eye drops to numb their eyes before the procedure. The patient is then asked to focus on a special fixation light. A computer program is used to determine the amount of laser energy to deliver to the eye during the procedure. The surgeon then folds a flap of corneal tissue away, revealing the middle layer of the cornea. This process flattens the cornea, reducing the converging power of the eye.

Before undergoing the procedure, an eye doctor will evaluate the shape and thickness of the cornea. He will also evaluate pupil size and any refractive errors. He or she will also examine the tear film and prescribe a precautionary treatment to help reduce the risk of dry eye following LASIK. The surgeon will then use a corneal topographer to create a map of the cornea or the front surface of the eye.

Side Effects

Although LASIK surgery is a safe and effective procedure, some patients do experience a few common side effects. These include blurred vision, sensitivity to light, glare, and double vision. Patients may also experience minor vision fluctuations for several days. These effects tend to subside over time as the patient recovers from the surgery.

There are no established rules governing the disclosure of LASIK surgery risks to patients. However, the FDA encourages them to educate themselves on the risks and consult with a surgeon before undergoing the procedure. The FDA notes that the number of LASIK procedures performed annually topped 1.4 million in 2000.

Infection of the eye is another common LASIK surgery side effect. To reduce the risk of infection, patients are given an antibiotic eye drop before the procedure and afterward. They should also avoid wearing eye makeup and certain activities after surgery.

Cost

The cost of LASIK surgery can vary depending on the type of procedure performed. For example, some LASIK centers charge more for “custom” procedures, which use a map of the actual cornea to correct higher-order aberrations in the eye. The cost of the surgery may also include the cost of medications required for recovery. Some patients’ medical insurance plans may cover these costs. Others may have to pay a copay.

LASIK surgery can cost $1,500 to $2,000 per eye. Many LASIK centers offer financing plans. Some offer interest-free financing for a period of 12 to 24 months, while others offer extended financing plans up to 60 months. While many patients may be concerned about the costs, financing can make LASIK more affordable.

Some insurance plans cover the cost of LASIK surgery. These plans are often advertised as “zero-down” or “0% interest” for up to two years. Many vision plans also offer extended interest plans for four or five years. Another option is to use a credit card to finance your procedure.

Facts About Astigmatism

Those who suffer from astigmatism must be aware of its consequences. For example, the condition may affect their ability to drive at night, which can pose safety issues. It can also affect their academic performance. Listed below are some Facts about Astigmatism. You can use this information to better understand the disorder and what you can do to manage it.

Myopic Astigmatism

Myopic astigmatism is a condition where the curvatures of the cornea and lens are not matched. The result is blurry vision when you look at objects at a distance. This condition can cause eye strain and even headaches. Treatment is available and can help slow the progression of this condition.

There are two types of myopic astigmatism. One type occurs when a principal meridian is farsighted, while the other is nearsighted. Compound myopic astigmatism results when one or both principal meridians are farsighted, causing the image to appear out of focus.

Hyperopic Astigmatism

If you think you might have hyperopic astigmatism, you should make an appointment with your eye doctor. They can diagnose the condition and offer treatments. Treatments may include glasses or contact lenses that correct the problem. Laser surgery is another option. A thorough eye examination is also recommended every year.

Hyperopic astigmatism can cause blurred vision. This condition affects both eyes. There are two types: simple astigmatism and compound astigmatism. Both forms cause different focal points to be out of focus. In compound hyperopic astigmatism, one principal meridian is farsighted while the other is nearsighted.

Mixed astigmatism

A person with mixed astigmatism usually experiences blurred vision due to the difference in curvature between the two sides of the eye. This condition can also cause problems seeing in low light or in the dark. Corrective lenses or glasses are the best way to correct this vision problem. These lenses help to direct light onto the retina properly. If you suspect that you may have astigmatism, it is best to visit your eye doctor for an evaluation.

The primary cause of mixed astigmatism is an unequal curvature of the cornea. Treatments for this condition include glasses, contact lenses, and laser eye surgery. However, unlike non-mixed astigmatism, this condition is not predictable. This is because there are a variety of possible causes and treatments.

Lenticular Astigmatism

There are two types of astigmatism in the eye: lenticular astigmatism and corneal astigmatism. Both types require corrective eyewear that corrects astigmatism. In severe cases, prescription glasses and contact lenses may be required. A toric lens may sometimes be needed to correct the eye’s astigmatism. In such cases, toric lenses may be permanent or removable like regular contact lenses.

Lenticular astigmatism is caused by a cornea that is curved too much. This causes a refractive error, which means that light will not focus in one spot on the retina. Consequently, the image will appear distorted or blurry. It can also occur when the cornea is irregularly shaped, causing the lens to become distorted.

Corneal Astigmatism

Corneal astigmatism is an optical condition that affects the eye’s shape and clarity. A doctor can determine if you have this condition by measuring the curvature of the cornea. There are two ways to do this. The first is to use a keratometer. This instrument measures light reflecting off the cornea’s surface and are essential for proper contact lens fitting. The other way is to use corneal topography, which provides images and measurements of the cornea and its shape. This type of testing can help determine the amount of astigmatism and the best treatment for it.

Corneal astigmatism is a common eye condition. Most people suffer from some degree of this condition. The irregular curvature of the cornea causes light to be refracted unevenly. This translates to blurred vision. Astigmatism is caused by genetics, and infants born prematurely have a greater risk of developing it.

LASIK Surgery

The goal of LASIK eye surgery is to correct your astigmatism using a cool laser beam to change the curvature of your cornea. Although many stigmatized patients can benefit from the procedure, not all can. Patients must meet a few conditions in order to be considered a good candidate. For instance, they must have dark-adapted pupils, high refractive error, thick corneas, and no systemic conditions. A thorough eye exam will help determine if you are a candidate.

Although LASIK is a safe and effective procedure, it does not guarantee a 20/20 vision. In most cases, patients will have vision significantly improved after undergoing LASIK. Many patients see better than they did before, leading to a newfound sense of independence. Furthermore, patients will experience a higher quality of life, as they will be able to play sports and work without relying on glasses.

Treatment

Treatment of astigmatism can include a range of options. It can range from contact lenses inserted into the eye to laser surgery, which can correct more severe forms of the problem. A physician can determine the extent of astigmatism by performing a visual acuity test. During the exam, a doctor may use different instruments to measure the degree of the cornea’s curvature.

While there is no single, definite cause of astigmatism, genetics plays a large role. It can also develop later in life or as a result of eye surgery. People with astigmatism often experience both nearsightedness and farsightedness. In some cases, astigmatism can be caused by another eye condition called keratoconus. This eye condition affects the clear tissue in the cornea and results in cloudy vision and sensitivity to bright lights.

Color Blindness – Causes, Symptoms, and Treatments

Color blindness is a common condition, which is often diagnosed in children during routine vision screenings. It typically doesn’t affect a child’s daily functioning, but it can cause problems with learning colors and interpreting instructions and systems that use color codes. If your child seems to be struggling with these problems, make an appointment at Elite Vision Centers.

Red-Green Color Blindness

For those with red-green color blindness, there are several treatments and medical devices to help them see colors clearly. Some of these treatments involve wearing special contacts or glasses. Others involve learning how to recognize and memorize the colors of objects. In some cases, people with color blindness can use smartphone apps to learn how to recognize colors. Children should inform their teachers of their condition since it can affect their schoolwork.

There are three main types of red-green color blindness: protan color blindness (RCV), deuteranopia (Dichromacy), and deuteranopia (Dichromacy). These three types of color vision deficiency are inherited through the X-chromosome, which has an X-linked recessive effect. Although some treatments may improve symptoms, none of them can permanently restore color vision.

Red-green color blindness causes, symptoms, and treatments depend on the cause. The disease is caused by a decrease in the number of cones in the retina. These cells are responsible for detecting light and fine detail. Eventually, cones cannot function properly. In children, red-green color blindness may lead to less sharp vision. In some cases, it can also develop in combination with other vision problems. If it is not diagnosed early, the affected person may never realize that they suffer from the condition.

Blue-yellow Color Blindness

People with blue-yellow color blindness can’t see figures in the blue or yellow range. The disease is caused by damage to the retina, which is responsible for seeing colors. The condition is also known as tritanopia and can be diagnosed through a color-blindness test, such as the Ishihara Color Vision Test, which was invented more than 100 years ago by a Japanese ophthalmologist. During the test, patients look at a series of dots, but they cannot see the numbers. This is because these colors are mixed together, so their normal vision is confused.

Blue-yellow color blindness is caused by changes in a gene called OPN1SW. This gene is responsible for distinguishing shades of blue and green and makes it difficult to distinguish between yellow and blue. The condition can also make yellow appear pink or violet, depending on the degree of the gene mutation. Blue-yellow color blindness affects one in every 10,000 people and is present in both sexes.

Inherited Color Deficiencies

People with color blindness have trouble recognizing and distinguishing certain colors, such as yellow, orange, and red. The condition is typically inherited and affects a small percentage of people. The genes that cause it are found on X chromosomes. In males, there is only one copy of this gene; in females, there are two copies. The lack of a second copy means that the person cannot compensate for the missing one.

Though there is no cure for this disorder, treatments for the underlying problem can improve color vision and reduce the severity of the symptoms. Regular eye examinations and visits to healthcare providers will help you prevent this condition from getting worse. You can also take steps to prevent it from developing by treating any underlying disease that is causing the problem.

A comprehensive eye examination can determine the extent of your color vision problem. During a test called a pseudoisochromatic plate, patients are shown a series of different colored dots. The patient is then asked to identify a number among the dots. Individuals with normal vision, they will be able to recognize the numbers, but people with color blindness will not be able to do this.

Treatments

If you have noticed that your child is having a difficult time learning to distinguish colors, you should get them checked out by a doctor. This condition is inherited and runs in families. You are more likely to develop this condition if you have a close family member who is colorblind. The best time to catch color blindness in its early stages is before it causes a significant problem.

Acquired color blindness can be caused by a number of different conditions that affect the retina and optic nerve. Your color vision may also be affected by certain medications. Certain antipsychotics, for example, can cause changes in color perception. Also, certain types of antibiotics, such as ethambutol, can damage the optic nerves.

In some cases, you may be able to correct the condition by wearing special contacts or glasses. Other times, a color-corrective surgery can help you see certain colors more clearly.

Causes of Low Vision

Low vision can be caused by a variety of factors. These include age-related macular degeneration, glaucoma, diabetes, and amblyopia. These problems can affect a wide range of people. A specialist can help you understand which factors are at play. These conditions can lead to vision problems that affect your daily life. If you’re concerned that your vision is decreasing, it’s a good idea to seek treatment early. You can visit this site to find an eye doctor and book an exam.

Amblyopia

The first step to treating amblyopia is correcting the refractive error. If the condition is severe, eye surgery can be an option. If the visual impairment is only mild, glasses or eye patches can be used to train the brain to use the weak eye. These devices are usually worn for two to six hours a day while the patient is awake. This treatment can last for months or even years.

Amblyopia is an eye condition that affects both eyes. If it is detected at an early age, it can be treated. Symptoms include strabismus (when one eye doesn’t line up with the other), difficulty with depth perception, and the suppression of blurred images. The main difficulty with amblyopia is that the brain can’t effectively use both eyes together because it is unable to process the information received from the eye that’s affected. This can cause problems with depth perception, scanning eye movements, and visual decision-making, including driving.

Early detection of amblyopia is crucial, especially in children. Regular eye exams are essential for children younger than six years old. During these visits, doctors can evaluate both eyes for signs of amblyopia, including a decrease in eye-tracking ability, and detect any abnormalities that may be causing the problem.

Age-related macular degeneration

Age-related macular degeneration, or AMD, is one of the leading causes of vision loss in older people. This degenerative condition affects the macula, the small part of the retina that controls central vision. The condition causes a loss of central vision and may affect people’s ability to recognize faces and center objects. People with this condition often have difficulty reading, driving, and doing other tasks.

There is currently no cure for AMD. However, certain treatments can delay or prevent vision loss. A physician can check your eyes for signs of AMD during a routine eye exam. They will look for yellow deposits under the retina called drusen. When they detect these deposits, they will likely diagnose AMD.

If you suspect that you may be developing age-related macular degeneration, your doctor may recommend an angiography or OCT to check the health of your retina. Angiography involves injecting a dye into your arm, and a photographer takes pictures as it flows through the retina. The pictures can show leaky or new blood vessels in the macula. OCT tests can also detect fluid under the retina without dye. Getting an early diagnosis is crucial for slowing the progression of this condition.

Glaucoma

People who suffer from glaucoma must take medications to lower eye pressure. Treatment can include using medications to relax the muscles in the eye or surgery to create a drainage canal. If surgery is not a viable option, family members can visit the affected person to remind them to use their medications. They can also help arrange transportation to follow-up appointments. If left untreated, glaucoma can lead to permanent vision loss.

Although early detection of glaucoma is the most important step in preventing serious vision loss, some symptoms will not be apparent until the disease is advanced. During an initial screening, a doctor can measure the pressure inside the eye. This will help them determine whether glaucoma is the cause of your low vision. If the pressure is too high, the optic nerve will be damaged. Taking medication is important for preventing glaucoma. However, it is also important to note that once the condition has progressed, loss of vision is irreversible.

The most common type of glaucoma is known as open-angle glaucoma. It occurs when the drainage canals of the eye are not able to drain fluid properly, causing elevated eye pressure. The trabecular meshwork is the drainage system of the eye, located at the angle where the iris and cornea meet. The condition tends to run in families, and scientists have identified genes that may contribute to high eye pressure and damage to the optic nerve.

Diabetic retinopathy

Diabetic retinopathy is primarily caused by damage to the blood vessels in the retina, the light-sensitive layer of tissue in the back of the eye. This condition results in blurred vision and sometimes even blindness. The affected blood vessels in the retina can rupture or become swollen, leading to an increased risk for retinal detachment. Often, this condition affects both eyes.

The progression of DR is characterized by different stages. The early stage is known as a nonproliferative stage. The blood vessels in the retina grow abnormally in response to ischemia. This leads to the formation of scar tissue and eventually to the detachment of the retina from the back of the eye. Diabetic retinopathy is often caused by diabetes, but other medical conditions may also be responsible.

Diabetic retinopathy can be treated with various medications and laser surgery. These treatments can reduce macular edema and slow the growth of new blood vessels. These procedures can help patients regain their independence and minimize their risk of severe visual impairment.
