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.

You can modify the display settings of your computer in the following manner to reduce eye strain:
• Brightness-Set the brightness of the display to a level, which equals the brightness of your workplace.
• Text size and contrast-Modify the text size and contrast according to the comfort level of your eyes. For most people, black text colour on a white background ensures minimum eye strain and maximum convenience.
• Colour temperature- The spectrum of visible light, which a colour display usually emits is its colour temperature. Blue light is considered to cause more eye strain. So, you should decrease the colour temperature to minimize the amount of blue light emitted by your computer’s display.

4. Try some eye exercises
You can practise some easy eye exercises to prevent your eyes from getting tired. Try staring at a distant object for 10-15 seconds and then looking at any nearby object for another 10-15 seconds. Return your gaze to the first object. Repeat 10 times.

7 Easy Ways to Get Relief from EveryDay Computer Eye Strain

Styes are normally caused by a proliferation of natural bacterial flora within the eye. This causes an inflammatory reaction and is known to affect children more than adults. It resembles a pimple in exterior appearance and may grow both inside and outside of the eyelid. The symptoms of styes include redness, pain, swelling and tenderness. Though the styes do not lead to any kind of visual problems, they can cause significant discomfort.

What can cause styes?
Your eyelids have lots of tiny oil glands, which can become clogged by dead skin, dirt, or oil buildup. When a gland is blocked, bacteria can grow inside. This is what causes a stye to develop.

What are the symptoms of styes?
The most common symptom of styes includes swelling of the eyelid, redness, pain, tenderness, eyelid crusts and burning in the eye. It frequently leads to a yellowish-white discharge which becomes very uncomfortable and may also continue to drain out of the eye. Doctors recommend not to press or squeeze the styes as it may lead to further complications.

You should call your doctor if:

The child`s eye is swollen shut
He has a severe pain
He has a high-grade fever
Swelling lasts for more than 20 days
Pus continues to drain from the eye
His eyelid bleeds
He has problems with his vision
Homeopathic medicines for sty are safe and effective with no side effects. They play a vital role in improving the health and immune levels of the body. The recurrence of any symptoms in a body can be prevented by homeopathic medicines. These medicines are easy and comfortable for all age groups as they taste sweeter and give quicker results.

Styes tend to dry out on its own although applying homeopathic medication can aid in hastening the process of healing.

Amalki: This homeopathic medicine aids in repairing damaged tissue which in turn aids the stye infection to dry out. It is recommended to add a teaspoon of Amalki, which is available in most homeopathic outlets, into a glass of pure water. Then the mixture must be left on its own for the whole night for at least 10 to 12 hours. The mixture should then be filtered and used for washing the affected eye.
Heper Sulphur: Heper sulphur aids in speeding up the rupture of styes so that the pain is instantly relieved. This remedy is particularly suited for the styes that cause significantly red and swollen. It also aids in reducing the tenderness and swelling. In the case of some children, styes tend to secrete a liquid discharge and are extremely painful. Heper sulphur along with warm compress can be extremely helpful in relieving the pain. 
Pulsatilla: Some styes do not cause any pain but cause significant swelling and secrete a yellowish discharge. People affected with such type of styes can be significantly benefited by the use of homeopathic remedy called pulsatilla. It has also been found useful in preventing reoccurrence of styes.
Staphisagria: Staphisagria is for chronic or recurrent styes that appear mainly on the upper eyelid. The eyes are very dry and have rheum. The corner of the eye and the edges of the eyelids may be chapped and infected.
It is important to keep the eye clean and flush it with cold water. If the pain and related symptoms do not go away after 3 to 4 days, it is best to consult a doctor for further treatments.

Styes - How Homeopathic Remedies Can Help?

An eye allergy or allergic conjunctivitis is a condition that strikes when certain substances irritate the eyes, which can cause a reaction. This reaction has varied symptoms starting from inflammation to watering and even redness and an itching sensation. So how can you tell if you have an eye allergy? this article will tell you all you need to know!

Causes: to begin with, this is an immune response that happens when the eye comes in contact with substances like dirt, grime, pollutants, pollen, nettle, pet hair, smoke, mold and more, which may cause irritation. These are typically known as allergens. The immune system takes these allergens to be invaders and begins attacking the same by releasing chemicals that cause these allergic reactions. Also, an eye allergy may be a symptom or outcome of other conditions like asthma, hay fever, or even eczema.

Symptoms: the eye usually bears a pink or red appearance when the patient is suffering from an eye allergy. Also, watery eyes are a common sight during this condition while scaling around the eyes may also take place. Further, itching and burning sensation may be felt by the patient and swelling or puffiness can be seen. The symptoms may afflict one or both eyes. The patient may also have a runny nose or stuffy nose as well as nasal congestion.

Difference between eye allergy and pink eye: conjunctivitis or pink eye is usually caused due to bacteria or a virus that spreads infection in the eye. But eye allergy is caused due to a response of the immune system that leads to an allergic reaction. While the pink eye may be a contagious condition, an eye allergy is not.

Diagnosis: the diagnosis of an eye allergy will be done with the help of various tests conducted by an ophthalmologist. The skin prick test will help in introducing allergens to find out if the spot gets raised or suffers from inflammation. Also, the doctor will check for other ailments like asthma and eczema.

Treatment: there are varied methods of treating this condition. To begin with, the doctor may prescribe medication like decongestants and antihistamines as well as steroids for more severe and persistent cases. Also, injections may be prescribed in order to do away with the allergic reaction and eye drops containing olopatadine hydrochloride may also be used.

Home remedies: staying away from allergens and using a warm and clean washcloth over the eyes, for a few minutes every day, may help in relieving the painful symptoms of the condition.

Do not forget to consult your doctor before you try any natural or home based remedies.

3. Angle-closure Glaucoma
4. Congenital Glaucoma
5. Secondary Glaucoma
6. Glaucoma suspect

2. An attack of angle-closure Glaucoma includes the following:
a. Severe pain in the eye or forehead
b. Redness of the eye
c. Decreased vision or blurred vision
d. Vision rainbows or halos
e. Headache
f. Nausea
g. Vomiting

Causes:
1. Eye injury
2. Inflammation of the eye
3. Dilating eye drops
4. Blocked or restricted drainage in your eye
5. Use of steroid-containing medications (pills, eye drops, sprays)
6. Poor or reduced blood flow to your optic nerve
7. High or elevated blood pressure

Who is at Risk for Glaucoma?
People with more risk of developing Glaucoma include people who:
1. Are over age 40
2. Have family members with glaucoma
3. Have high eye pressure
4. Are farsighted or nearsighted
5. Have had an eye injury

Types, Causes and Symptoms of Glaucoma

There are many common measures people take to improve their eyesight or to improve their vision, including wearing glasses, lenses, and many more. Here are some effective exercises, which can prove to be highly beneficial to improve your eye health:

1. Stretching
This is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds and then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.

2. Flexing
This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.

3. Focus switching
This particular eye exercise is probably the most useful one to improve eye health. In this eye exercise, you have to hold something at a reading distance and cover the other eye. You then have to find something that is at least twenty feet away and trace its shape with one eye closed. With one eye closed, trace more shapes, which are twenty feet away.

4. Palming
This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to distress the eyes.

5. Deep blinking
This is also an incredibly useful exercise for distance vision. What you have to do is to place some large letters are at a fair distance and then sit on a chair. You have to then close your eyes and tighten all your muscles for 5 seconds. After 5 seconds are over, you have to open your eyes and then you have to see the letters for a second or two. The more number of times you do this, the more clearly you will be able to see the letters after reopening your eyes.

However, these eye exercises are not universally accepted by all doctors.
