1.   What should I do, if any chemical fall in my eyes?

Do not rub your eyes. Wash your eyes well with water immediately and consult your eye specialist.


  1.   What if my eyes get injured with sharp objects like glass or iron rod etc?

Do not rub your eyes. If any particle is stuck in the eye, do not try to remove it by hand. Consult your eye doctor immediately.

Though you do not see any signs outside your eyes or no defective vision following an injury, it is better to consult your eye doctor for a comprehensive eye check up because there may be a hidden injury which can lead to loss of vision in future.


  1.   Why are my eyes watering frequently?

Watering of eyes can be of many causes. It can be a sign of simple allergic reaction to a viral infection. Watering may or may not be associated with redness and present only while going out, is a sign of allergic reaction. A simple watering can be a sign of serious infection in drainage pathway of tears/dysfunction in production of tears. Any infection can give signs of pain, discharge and redness. If irritation in your eyes persists, consult your eye specialist for further management.



  1.    What is cataract?

It is cloudiness of crystalline lens inside the eye. It occurs as a normal ageing process. For some people, due to their metabolic changes inside the body, it can occur very soon or very late. People with diabetes and other health problems have the chances of getting cataract at a younger age. Person who had any injury to their eye is also at risk of developing cataract at a younger age/ following injury. Rarely, sometimes cataract can be present when a baby is born. This could be due to developmental anomalies or any abnormality during delivery or pregnancy.  There are some other reasons too. When the person is under steroid treatment for a long time, then he/she is at a risk of developing cataract at an earlier age.


  1.    Whether cataract can be treated/reduced with wearing spectacles or using any   eye drops?

No. As discussed in previous answer, cataract is cloudiness in lens, which is inside. Thus there is an obstruction in the pathway of light to back of the eye due to cloudiness of lens. There is no other pathway for the light to pass inside. It has to pass through lens only. The cloudiness cannot be reduced using any eye drops or spectacles. Surgical removal of cataractous lens is the only option available.



  1.   Why do my eyes become tired, after working with computers for long time?

The letters on the monitor are made up of tiny objects called pixels and also the monitor flickers at a particular rate (which is normally invisible to our perception). But these causes, slight difficulty for our eyes to focus the letters on monitor. This causes, your inner eye muscles tighten up, causing your eyes to get irritated, dry up and feel uncomfortable. In addition, lack of sleep, fatigue, poor lighting and an incorrect posture (such as slouching on your chair), can aggravate eyestrain. These all together can give you feelings of tired eyes.

      To get relief from this, you need to make some changes in your ergonomics and routine work without affecting your work. Set the brightness of your computer at low glare level i.e. at your comfort level. Fix an antiglare screen on to your monitor. Adjust your monitor height or height of your chair in such a way that the centre of the monitor is approximately 15 to 20 degrees below your eye level. This reduces the need for opening the eyes widely to look at monitor. Slightly looking down to monitor needs only small opening of your eyes thus reduces evaporation and dryness of your eyes. Another important thing is to take breaks atleast every 20minutes of your work for 20 seconds. During this break look at a distant target (around 20 feet). For further reading on this, refer Computer Vision.


  1.    Will reading in dim light/traveling affect my eyes?

Yes. For proper functioning of our eyes, we need to have adequate lighting on the reading material. It should not be more or very less. Avoid glare on reading material. Otherwise, eyes will strain and end up in head ache.

      While traveling, the reading material keeps moving according to the jerk of the vehicle. Though we are able to read while traveling, it causes great trouble for our eyes to focus on the letters since it is moving. This again causes eye strain and head ache. So kindly avoid reading while traveling.



  1.    Do all the red eyes spread from one person to another?

No. Only infections caused by Viral or Bacteria or fungus are contagious. Some eyes get redness due to constant straining of eyes or dryness or allergies. These types of redness are non-contagious. In case of infections, it is important to maintain cleanliness to avoid spreading of disease. These types of redness can be associated with other symptoms such as pain, discharge, foreign body sensation, watering and irritation. In order to diagnose the disease better, consult your eye doctor immediately.



  1.     Why do I need to wear reading glasses after crossing 40 years?

It is a normal ageing phenomenon. Crystalline lens inside our eye is helping us to focus object at far and near by changing its shape. As ages, this property of lens reduces slowly. It is called Presbyopia. Commonly, after 40 years, it becomes more and we need to have a substitute for this. Reading glasses are these substitutes. As age increases, the power of reading glass also changes according to further decrease in lens flexibility.



  1.    How often do I need to get my prescription change?

It depends on each individual. For kids, since there are minor changes happening inside their eyes as a part of growth and development, their refractive status also changes with time. Sometimes it may increase or decrease. Thus it is better to have your kids checked for their eyes minimum 6 months in a year. For adults, since,  changes occur as a part of ageing (refractive status of lens, vitreous and presbyopia), they also need to have their eyes checked at least once in a year. Those people with any other eye disease (keratoconus/diabetic retinopathy) or other health problems (Diabetes/Hypertension/Cholesterol etc) must check their eyes in every 6 months or according to your doctor’s advice.


  1.    Does watching Television close by, decrease my child’s vision?

This is a misconception. Most of the time, Kids watch television very closely Majority of times this could be out of curiosity or sometimes because of defective vision. It is not that their vision will decrease since they watch television sitting very close to it. But in order to rule out defective vision and ensure your child’s vision is good, have a comprehensive eye care for them.

Watching television very close should not be encouraged anyway because, there will be harmful radiations coming from television.

  1. Will the spectacle power (Myopia/ Hyperopia) decrease with constant wear of   spectacles? OR

    Is there any chance that we can avoid spectacles after using spectacles for some period of   time?

Not always. Some kids will have defective vision since birth or develop defective vision few years after birth. If it is detected earlier, they will get good vision with their spectacle power. They may need to wear spectacles for their lifetime. If it is detected late, their vision will improve with spectacles (if worn constantly) but not to the full extend. Here again, they may need to wear spectacles for their lifetime, because without that power, their vision will be even worse. With time, power might or might not change depending upon the type of refractive error they have.


  1. Will the use of spectacles constantly, decrease vision of my eyes or increase spectacle power with time?

Never. Use of spectacles will never cause further decrease in your vision. It only helps to see things better than not using spectacles. Spectacles are only an aid to improve one’s vision to normal vision range and make their life better. Each individual has his/her own limit of refractive error.  It may increase or decrease based on each person’s health and eye condition irrespective of spectacle use and vision will change accordingly. . Even if you do not wear those spectacles also, the power will change if it has to. You have to consult your eye specialist in regular intervals to check any change in power.


  1.     Can I use my eye glass prescription to buy over-the-counter contact lens?

No. For contact lenses, there are few other measurements to be taken for best fit of lenses apart from spectacle power. And also, for high refractive errors, there may slight variations in the spectacle power and contact lens power. Thus spectacle power prescription cannot be used to get your contact lenses.


  1.     Can I wear Contact lenses?

It depends on nature of your eye, your refractive error (spectacle correction), your mode of work and your preferences to cosmoses etc. If your eyes have any signs of eye infections and you are working in a dusty environment, you may need to consult your eye specialist and then decide on contact lens. Any one who has refractive error (Spherical/cylindrical) and who wants to get rid of spectacles can switch over to contact lenses considering the fact that their eyes do not have any infections. Wearing Contact Lenses instead of spectacles will never reduce /increase your refractive error as such. Contact lenses are only an aid and just substitutes for spectacles to provide you better vision. You have to consult your eye specialist in regular intervals to check any change in power.


  1.  Why do my eyes twitch frequently?

Twitching is sometimes not at all a serious issue. But there are some cases, where you have to really consider it as a serious illness. Twitching which is present only when the person gets tensed or concentrating more on his/her work can be considered as a physiological phenomenon. It happens when more neuronal impulses traverses through his/her nerve fibers (i.e. when person gets tensed/concentrating). Twitching which is present always in a regular interval, need to be checked immediately as it can be any sign of neuro-vascular abnormality.


  1.  Are different powers in both eyes a problem?

If the different powers are present since birth or childhood, it does not cause any problem to the person. It could be due to physiological and anatomical differences in both eyes. If there is a large difference in powers of both eyes developed suddenly (acquired), person may feel slight discomfort or double vision etc. In such cases, need to be evaluated and prescribed glasses according to eye specialist opinion.


  1. Is the eye pressure related to blood pressure?

Ans. To some extend, but not always. Like blood pressure do have a normal value for reference, eye pressure also has a normal range within 20mm Hg.  Eye pressure is the pressure exerted by aqueous humor inside the eye. Small variations in blood pressure can affect eye pressure minimally. There are not directly related.
