People are well aware of the harmful effects that UV rays have on the skin, but very few know that UV rays can damage their eyes as well. The tissue that human eye is made up of is one of the most sensitive tissues in the body and hence, the most vulnerable. The increasing level of UV radiation reaching the Earth s surface every minute has made it indispensable to take the required precautionary measures to protect the eyes.

What are UV rays?

Sunlight consists of 3 types of radiations - Infrared, Visible light and UltraViolet. Artificial sources like lasers, tanning beds and welding machines also emit UV radiation.

There are three types of UV radiations - UV-A, UV-B and UV-C. 

UV-C is absorbed by the ozone layer and does not possess any risk. It is UV-A and UV-B radiations that adversely affect the eyes and vision.

Impact of UV rays on  eyes

Too much exposure to UV rays can affect vision, harm the eyes, and deteriorate overall eye health. There are various eye problems that are aggravated by excessive exposure to UV radiation:

Macular Degeneration: It is caused by damage to the retina over time by UV rays. It leads to age-related blindness. Too much exposure to UV rays increases the risk of developing macular degeneration.
Cataract: It is the clouding of eye s natural lens - the part of the eye that focuses the light we see. Too much exposure to UV rays increases the risk of developing cataracts. 
Pterygium: Often known as  surfer s eye , pterygium is a pink, non-cancerous growth that is formed on the conjunctiva. UV rays are believed to be responsible for the development of this growth.
Skin Cancer of the Eyelids: Too much exposure to UV rays can cause skin cancer in and around the eyelids.
Photokeratitis: Popularly known as corneal sunburn or  snow blindness , photokeratitis is caused due to excessive short-term exposure to UV-B rays. Photokeratitis occurs when you spend long hours at the beach or skiing. It sometimes leads to temporary vision loss. 
How to protect the eyes from harmful UV rays?

Here are some tips to help ensure that eyes are protected against harmful UV rays:

Always use quality sunglasses that block out 99-100 percent of both UV-A and UV-B radiation when outdoors.
Stay away from tanning beds, and if you use them occasionally, always wear eye protection. 
Wrap around frames should be used if you spend a lot of time outdoors.
Be sure to see your doctor at least every two years.

UV Rays - Are They Damaging Your Eyes?

Glaucoma is a leading cause of blindness in people across the globe. It damages the optic nerve that carries sensory images from the retina to the brain. A faulty eye pressure is responsible for damaging the very delicate optic nerve fiber causing small blind spots in the retina. Unfortunately, for most patients this disease only gets diagnosed when the number of blind spots is on the higher side.

Types of Glaucoma

Open angle: This is a type of Glaucoma which results from the blockage of the drainage angle of the eye resulting into an increased eye pressure.
Angle closure: This is the kind of Glaucoma which results from the narrowing down of the drainage angle leading to complete blockage.
Target segment of Glaucoma

Family history: Inheritance surely plays a role in case of Glaucoma too. If Glaucoma runs through families of an individual, there are higher chances of getting this disease. Although there is no hard and fast rule about it, the risks of inheriting this disease are on the higher side.
Eye injury: If there is any history of previous eye injuries, the probability of the onset of Glaucoma cannot be turned down. Specially, if the injury is related to optic nerve, there are very high risks involved.
Bilateral Oophorectomy: Dual Ovary removal before the age of 40 results in deficiency of estrogen resulting in Glaucoma. Although most surgeons warn their patients of the possible risk of these procedures, many surgeries such as these have resulted in patients losing eyesight in the form of Glaucoma.
Patient with Diabetes: In case of acute diabetes, retina gets damaged and the eye starts producing new blood vessels on the iris resulting into an increased eye pressure. This condition often leads to Glaucoma due to blockage of fluid flow in the eye.
Eye Conditions: Myopia, multiple surgeries to the eye, blunt trauma etc. can lead to Glaucoma. A patient who has undergone any kind of eye surgeries suffers from inflammation. However, major inflammation is often found twisting blood flow in the eye resulting into Glaucoma.
If a patient is 40 or above: After a person reaches 40 years of age, a lot of diseases start cropping in to the body. Studies show that Glaucoma has a higher frequency in people who is more than the age of 40 or above.
High eye pressure: A patient with an eye pressure of above 21 mm HG is also at a very high risk of getting glaucoma. For a normal person the IOP lies between 10 to 21 mm HG.
Blood flow related disease: Diseases such as acute migraine, hypertension and low blood pressure which involves blood flow related problem often aggravate to glaucoma.
Ethnic Background: Statistics show that people from Afro American, Hispanics, Asian and Caribbean background have greater chances of being affected by Glaucoma.

Glaucoma - Are You at Risk?

High blood pressure can lead to hypertension, which is known to cause a variety of debilitating side effects or symptoms in the life of the patient. It can also lead to a number of related ailments which can affect the various organs of the body. The eyes are one of the organs that are most susceptible to this kind of spike in the body s blood pressure. Let us learn more about the connection between the two.

Retina: When high blood pressure goes untreated for a prolonged period, it can easily start to affect the blood vessels that can be found in the retina. The retina is the third or the inner most layer of the eye which is sensitive towards light and usually helps in refraction. This is where the light reaches so that one can focus clearly on an image. When the blood pressure of the patient stays high for a prolonged basis, there is significant pressure on the blood vessels in this part of the eye which can lead to an eye disease known as hypertensive retinopathy.

Symptoms: Symptoms of this eye disease include lack of clarity and focus when the eye comes to rest on an object, as well as headaches and other vision problems that typically spring from eye strain that one will go through while trying to focus even harder. It may be seen that the symptoms do not appear in the very early stages of this disease.

Diagnosis: The diagnosis of the condition is usually done by an ophthalmologist who will use an ophthalmoscope in order to project light towards the specific part of the eye so that the back of the eyeballs can be examined. The signs that the doctor will look for during the examination include narrowing of the blood vessels in this part of the eye, inflammation of the macula which is the central portion of the retina, and bleeding in the back of the eye. Also, the doctor will check for spots in the retina with the help of cotton swabs and exudates.

Treatment: The best and only way of treating this condition is by keeping one s blood pressure in control with the help of medication prescribed by the doctor.

Prevention: There are many ways of preventing the onset of this disease, including losing weight so that there is less pressure on the body. Also, one must stick to a healthy diet and exercise regularly after taking recommendations on the appropriate exercises from the doctor. Additionally, it is also important to see a doctor on a regular basis so that there is constant monitoring and regulation of the medicines and the blood pressure.

Alternatively, you can ask an optometrist to prescribe a simple saline solution to hydrate your eyes and give them a soothing feel.

Staring at the computer screen for a long time at a stretch can affect your eyes negatively. So, implement the 20/20/20 rule into your daily routine. According to this rule, you should remove your gaze from the computer screen every 20 minutes and then direct your vision towards an object kept at a distance of 20 feet for 20 seconds. This break helps your eyes to relax and refocus, consequently avoiding the occurrence of blurry vision.

3. Give your body a balanced diet and correct amount of sleep
Ensure that your daily diet contains green, leafy vegetables and fruits and food rich in antioxidants. These food products help in improving your vision to a large extent. Moreover, sleep for around eight hours every night to prevent eyestrain.

4. Make it a daily habit to perform eye exercises
The most effective technique to naturally improve your eyesight is performing eye exercises. Regular eye exercises not only enhance your vision but also give strength to your eyes.

Here's a simple exercise you can try. This works by applying heat to your eyes in order to relax them. For this, you can rub your palms together till they become warm and then place them on your eyes. Let your palms remain there for 10 seconds and then open your eyes.

It is also very important that you take care of your existing health problems like diabetes, hypertension, neurological problems or allergies and be regular with exercising such that it keeps your body fit and does not bear any impact on other organs like eyes.
