In today’s world, most of the work that you do is on your computer. With an increasingly digitized world, computers can’t be replaced. Though they have made your work easier, they do come with certain disadvantages as well. The rays emitted by a computer screen can be harmful to your eyes if exposed for an extended duration.
It is important that you take certain precautionary measures to protect your eyes:
1. Wash your eyes: Wash your eyes on a regular basis; it facilitates cooling and relaxation of the eyes. Make it a routine to wash your eyes at least 5 to 6 times in a day.
2. Get computer glasses: Use computer glasses to protect your eyes as they help to minimize the effect of the radiation from the screen. If you work for long hours in front of the computer, then you should consider getting a pair of computer glasses.
3. The position of your screen: The screen should ideally be positioned at an arm’s length and the viewing angle of the monitor should be around 35 degrees. Make sure you position your chair accordingly keeping these tips in mind.
4. Eye exercise: You should exercise your eyes to reduce the strain and relax your eyes. Follow the 20-20 rule wherein after working on your computer for 20 minutes, you redirect your gaze to an object that is around 20 feet away. This helps your eye muscles to relax and thus, improves your eye health.
5. Don’t work at a stretch: Take breaks in between your work sessions to reduce fatigue in your eyes. Constantly staring at a screen for an extended amount of time can cause problems in your eye. Take 2 minute breaks for every 30 minutes you spend working on your computer. This helps to reduce the strain on your eyes also helps to release tension in the muscles of the neck and back.
6. Blink more than usual: Blinking moistens your eyes and causes tear production which does not allow the eye to suffer from dryness. It also prevents eye irritation and helps in clearing out dirt from the eyes. If you wish to discuss about any specific eye problem, you can consult a specilized opthamologist and ask a free question.
When do you need this surgery?
This surgical procedure is ideal for people having following conditions, making spectacle use mandatory:
1. Hypermetropia or farsightedness - Close objects appear indistinct
2. Myopia or nearsightedness - Far off objects appears blurry
3. Astigmatism - Overall fuzzy vision
Advantages of LASIK:
Biggest advantage of LASIK is that it helps people to get rid of glasses and contact lenses, which sometimes are cosmetically unacceptable and in some cases are visually disabling.
Best part of LASIK is that it is:
1. Has a high success rate ( success rate is 96%)
2. Quick (total duration of surgery is hardly 5 minutes) and virtually painless
3. Adjustments can be made years later to alter the vision as per growing impairment in the future and advancing years
4. Does not require bandages or stitches
Who can go for LASIK:
Any person 18 years or older who fulfils the following criteria can undergo Lasik surgery
1. Stable refraction
2. Dilated retinal examination should be normal
3. Corneal thickness and topography should be in normal range
4. Adequately wet eyes
Irregular shape of the cornea is the main cause for astigmatism. It might also be caused because of the imperfect shape of the lens. Suffering from astigmatism is very common. You are either born with the condition or you might have developed it after an eye surgery. It is an incorrect concept that watching too much of television or reading without enough light causes astigmatism.
There are three different types of astigmatism:
1. Myopic astigmatism: When the principal meridians of the cornea are nearsighted.
2. Hyperopic astigmatism: When the principal meridians of the cornea are farsighted.
3. Mixed astigmatism: When one of the principal meridians is nearsighted and the other is farsighted.
It can also be classified in two other types:
1. Regular astigmatism: When the principal meridians are perpendicular to each other.
2. Irregular astigmatism: When the principal meridians are not perpendicular to each other.
Blurry or distorted vision, strain in the eye, eye discomfort, squinting and headaches are a few symptoms of astigmatism
If you notice the symptoms stated above, make sure you pay a visit to your ophthalmologist. If you are suffering from astigmatism, your doctor will do an eye test to check how much your eye is able to focus on light. After conducting his tests, he will determine how much power you have and you will have to wear glasses of that power. Apart from the option of wearing glasses or artificial lenses, you can also go for a surgery to correct the condition. LASIK is an option among the many other options of surgeries available.
Eat foods rich in sulphur. Foods like fish, green vegetables, pineapple, garlic, onion, olive oil, etc are rich in sulphur. Hence, eating these will help you battle astigmatism.
Here are some tips to keep your eyes cool and protected during the summer:
- Wearing sunglasses is very important when you are outdoors as it protects your eyes from the harmful UVA and UVB light. This will help in avoiding migraines and even serious conditions like cataract.
- Avoid midday sunshine. Stay indoors as much as possible during the middle of the day to avoid the sunshine then when the effect of the sun and ultraviolet radiation exposure are at their peak.
- When you plan to go for a swim, make sure you wear your swimming goggles. Otherwise you might catch conjunctivitis.
- You should not splash water into the eyes directly unless any foreign particles such as dust enter your eyes. This might damage the tear film of the eye, which protects your eyes.
- You need to maintain proper hygiene by washing your hands and face properly as soon as you reach home so that dust or grime does not enter the eyes as their entry can result in allergies and infections.
- You can keep a slice of cucumber on each of your eyes to relax and cool them down.
- 6 to 8 hours of sleep are a must as they help in revitalizing your eyes.
- Adding green vegetables, carrots, nuts, liver and fruits to your diet would be very beneficial for the health of your eyes.

A cataract is defined as a clouding of lens in the eye where your vision gets blurred. A cataract affects the eyes, when light that passes through the lens prevents a clearly formed image from reaching your retina. The disease is very common and usually develops as your eyes age or due to any injury caused to the tissues that cover your eye's lens.
Types of cataracts:
Senile Cataract: This is the commonest of all. It is age-related clouding of the lens. It can affect the near or distance vision and can also cause glare and change in glasses power.
Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes.
Traumatic Cataract: It can develop many years later after an injury caused to your eye.
Congenital Cataract: As the term explains, the disease may be inborn or some children might develop it at a later stage which often affects both eyes.
Radiation Cataract: It can form after you are exposed to some form of radiation.
A cataract surgery involves the extraction or cleaning of the cloudy lens, which is then replaced by a clear artificial lens.
Why does it happen?
There are lens that lies behind our iris and pupil which act much like a camera lens. It helps concentrate light onto the retina at the back of our eye to form a sharply defined image. Besides, the lens also helps our eyes to adjust focus and allows us to see things clearly both far away and up close. The lens is composed of protein and water where the protein is arranged in a manner to keep the lens clear thereby letting light pass through it.
However, as we grow old, some of the protein starts to become thick and cloud a small lens area. This is known as a cataract. With the passage of time, it may inflate and cover more of the lens, making it difficult for us to see.
Besides, there are other causes of cataract such as smoking, addiction of alcohol, prolonged sunlight exposure, to name a few.
When should you opt for a cataract surgery?
Believe it or not, but till date no eye drop or medication has proven to reverse or prevent the formation of a cataract. If a cataract is affecting your nearsightedness or alteration in your prescription, then new prescription eyeglasses may help to better your blurred vision. However, the only treatment for a cataract is the surgical removal of your natural lens. And, most eye doctors recommend this surgery only when the problem becomes severe and starts hampering your day-to-day activities, such as studying or driving at night.
