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?

Most of us take our eyes for granted. It has been often noticed that an individual splurges on expensive sunglasses for looking smarter. But, when it comes to the health of eyes, he or she is either ignorant or simply reluctant to do anything. This tendency is bad for the health of your precious eyes.

Remember, how you use them to stare at the screens of your gadgets all day long. Take out some time from your busy schedule and take care of your eyes. They are precious and vulnerable too.

Follow the tips below to keep your eyesight intact till your dying day:

Eat right for a good vision: It is very important to provide the right and sufficient amounts of nutrients to your body for developing or maintaining a good eye sight. Include nutrients such as omega-3 fatty acids, lutein, zinc, and vitamins C and E in your regular diet to boost your eyesight. Food items like green and leafy vegetables, salmon, tuna, and other oily fish, eggs, nuts, beans, and other non-meat protein sources, oranges and other citrus fruits or juices and oysters and pork are excellent for the eye. The intake of a balanced diet keeps you away from diabetes, which causes blindness.
Give up smoking: Cigarettes or other tobacco products are bad for your eyes. They make your eyes more vulnerable to diseases like cataracts, optic nerve damage, and macular degeneration.
Guard your eyes from sunlight: It has been found that long exposure to sunlight leads to damage of the eyeballs. This happens as the UV rays in sunlight have an adverse impact on our eyes. You must put on sunglasses when you are outdoors for a longer period. You must choose sunglasses which give you 90 to 100 percent protection against sunlight. UV rays can cause cataracts and macular degeneration.
Avoid the screen: It is advisable to not spend long hours sitting in front of the computer screen or TV. Take breaks while working on the computer. Also, remember blinking your eyes while staring at the screen to avoid drying up of the eyes. Blinking increases tear production, keeping the eyes moist and healthy.
Use safety devices: If you work with hazardous substances, it is advisable that you put on safety devices on your eyes for their protection.
Hydrate your eyes: In order to have a good vision, you must hydrate your eyes by splashing water on your eyes wide open at specific intervals in a day. When you wash your face after returning from outside, don't forget to wash your eyes as well. As you splash water on the eyes, the dust particles on the surface of the eyelid, gathered from outside, gets washed away. f you wish to discuss about any specific problem, you can consult a ophthalmologist.

Tips for Improved Eye Health

Astigmatism is a typical vision problem that occurs when the shape of the cornea is distorted due to injuries or other causes. With astigmatism, the lenses of the eye or the cornea curves. This irregular curve can change the way light refracts or passes through your retina. This causes hazy, fluffy, or twisted vision. Farsightedness and partial blindness are two different sorts of issues with the way light goes to your retina. Farsightedness is called hyperopia. Partial blindness is called astigmatism.

Types: There are two types of Astigmatisms. These are:

1. Corneal astigmatism
It happens when your cornea itself is distorted.

2. Lenticular astigmatism
Lenticular astigmatism happens when your lens is distorted.

Risks: Astigmatism can happen in youngsters and grown-ups. Your danger of creating astigmatism might be higher if you have any of the following:

1. A family history of astigmatism or other eye issues like dislocation of the cornea.
2. Scarring or diminishing of your cornea
3. Excessive partial blindness, which makes foggy vision at a separation
4. Excessive farsightedness, which makes hazy close-up vision
5. A past of eye surgeries, for example, cataract surgery (surgical expulsion of a blurred focal point)

Symptoms; The side effects of astigmatism include:

1. Hazy, Bended, Or Fluffy Vision At All Separations (Close-Up And Far Away)
2. Trouble seeing during evening
3. Lazy eye
4. Squinting
5. Irritation in the eye
6. Cerebral Pains

Diagnosis:

Visual Acuity Assessment Test

Patients are required to read letters from a graph at a particular distance to decide how well they can see the letters.

Refraction Test

A refraction test uses a machine called an optical refractor. The machine has various remedial glass lenses that are used to read an outline while looking through lenses on the optical refractor.

Treatment:

Keratometry

Keratometry is a route for your specialist to measure the bend of your cornea. They will do this by taking a look at your eye through a keratometer.


Corrective Lenses

Remedial eyeglasses and contact lenses prescribed by a specialist are the most well-known and least obtrusive solution for astigmatism.


Orthokeratology

Orthokeratology is a treatment that uses contact lenses to correct the deformation and flow of your cornea. You will wear inflexible contact lenses for certain time-periods. It is easier to wear them while you are sleeping and remove them during the day.


Surgery

Your specialist may suggest refractive surgery if your case is a serious one. This kind of surgery includes use of lasers or little blades to reshape your cornea. This will correct astigmatism permanently. The three basic surgeries for astigmatism are:

1. Laser in situ keratomileusis (LASIK)
2. Photorefractive keratectomy (PRK)
3. Spiral keratotomy (RK).

All these surgeries might carry some risks depending upon the symptoms of your problem. As innovation advances, it is very important for the patient to explore more options before choosing which refractive surgery is a good fit for him or her.

Types and Treatment for Astigmatism

If you have got diabetes, then it is quite natural that you will soon face acute eye troubles. This is the reason diabetic patients are always suggested to keep their blood sugar levels controlled so that eye troubles can be easily avoided. Thorough medical check-up is required in order to detect conditions of the eyes. Some of the commonest eye troubles occurring due to diabetes are cataract, glaucoma, blurry vision, diabetic retinopathy and others. 

List of eye diseases caused by diabetes

1. Diabetic retinopathy: when the retina's smallest blood vessels get severely damaged due to increased blood sugar, then this kind of eye condition occurs. Early detection of this eye condition can save your eyes, but if it is too late, then nothing can be done, and it might even lead to blindness.

2. Cataract: fogging or clouding condition can bring this kind of condition and this can only be corrected by wearing proper corrective lenses. However, if you fail to control diabetes, then in spite of wearing glasses, your eye condition might get deteriorated day-by-day. Glared or blurred vision is the most common symptom in this regard. 

3. Glaucoma: when the eye fluid is not drained properly, then this kind of eye trouble occurs. In fact, eye pressure increases to a great extent as a result of which delicate eye nerves can get severely damaged. The blood vessels of the eyes can get clogged causing greater interruption in vision. Medicines can make aqueous humor to get drained in a proper manner, and thus you should go for a proper eye check-up so that you can acquire the requisite medicines. Some popular symptoms of glaucoma are headaches, eye aches, blurred vision, watery eyes, vision loss and others. 

4. Diabetic macular edema: this eye disease mainly occurs in the advanced stage of diabetic retinopathy. Macula is nothing, but the most delicate part of retina and when it gets swollen, then you might face this eye trouble. Only medications can help you to get rid of the same and thus immediate medical help is needed. 

5. Blurry vision: though this is quite a small and temporary eye issue for diabetic patients, but this condition might turn into a serious one if you neglect to correct the same in the very beginning. You might even face blindness due to negligence of this trouble. Also, fluctuating sugar-levels should be stabilized so that this kind of trouble can be easily tackled.

Eye Problems Caused by Diabetes

Vision is one of our most important senses. Reduced vision that triggers the need for corrective glasses is one of the most common disorders associated with the eyes. Crossed eyes are another such common disorder that affects the eyes. In medical terms it is also known as strabismus. This condition is a result of miscommunication between the brain and the eye muscles that result in misalignment of the eyes. It is largely a hereditary condition and should not be confused with a lazy eye syndrome.

Crossed eyes can cause double vision and disorientation. Your depth perception may also be affected. It also causes eye strains and headaches that affect the quality of your life. This condition is seen mostly in children. If not treated in time, it can continue into the adult years as well. The development of crossed eyes in adults who have not suffered from this condition as children is usually a sign of a serious condition such as a stroke.

Some symptoms characteristic of this condition are:
1. Independent movement of eye balls
2. Tilting the head to a side
3. Squinting
4. Varied points of reflection in each eye
5. Frequently bumping into things as a result of impaired depth perception.

Treatment for this condition can be surgical as well as non surgical. Non surgical treatment aims at strengthening the eye muscles and treating the visual system as a whole. The aim is to not allow the eye to become lazy or amblyopic. Wearing an eye patch over the strong eye and forcing the weak eye to be used is one of the most common form of this treatment. Corrective glasses can also be used to treat this condition in cases where it has been triggered by excessive farsightedness. In some cases, medication may also be injected into the eye to relax the eye muscles.

Surgery to correct this disorder involves correcting vision by strengthening or weakening the eye muscles. To do this, a surgeon must first make a small incision in the outer layer of the eyeball to reach the affected muscles. To strengthen the muscle a small section is removed from the muscle and the remaining part is then rejoined. This makes the muscle shorter and forces the eye to turn towards that side. Alternatively, the doctor may make a partial cut across the muscle to elongate it and let the eye turn further away from it.

Crossed Eyes - How Can It Be Treated

LASIK stands for Laser In-situ Keratomileusis. This is a common eye surgery that helps in correcting vision problems. During this procedure, the cornea of the eye is cut across by a medical expert to raise the tissues and reshape them to correct vision. LASIK is suitable for patients who have shortsightedness, long sightedness or who suffer from astigmatism.

Here are the 5 benefits that a LASIK surgery offers:

1. Improved vision

A study reveals that 95% of the people who underwent this surgery achieved uncorrected visual acuity of 20/40 and 85% of the people achieved 20/20 vision. This procedure ensures that a patient achieves enhanced vision.

2. Quick results and recovery

This surgery enables you to return to your normal schedule immediately the day after the surgery. You can have clear and improved vision within a day.

3. Long- lasting outcomes

A minimum timeframe of 3 months is required for the eyes to adjust, after which LASIK results are permanently noticeable in a patient. No follow up procedures are required unless something wrong went with the surgery. The patient will continue to have improved vision unless there is any normal loss due to illness or aging.

4. No need of glasses

You no longer require glasses as your vision turns to normal post-LASIK surgery.

5. Goodbye contact lenses

LASIK surgery will help eliminate the need for contacts. You will be able to avoid all the problems pertaining to wearing a contact lens, including lens solution.
