Common EYE problems
EXCESSIVE STRAIN on eyes, especially during examinations, has given rise to some eye related problems among students. Some of the common problems are as follows:
Dry Eye
This problem arises due to the imbalance in the quantity or quality of tears ad is associated with gritty eyes, pricking or burning sensation, irritation or a feeling of a foreign body in the eyes. When faced with dry eyes, avoid contact lens wear, use a lubricating eye drop and reduce the time of work on computers. Care should be taken not to have the draught from a fan or air conditioner directed on the face as it could worsen the symptoms.
Computer Vision Syndrome
It is common for computer users to have dry eyes. This is because we don't blink much and keep our eyes wide open when working at the computer, resulting in drying up of the tear film. Many reasons can result in this condition.
Poor head position in relation to the computer;
Lighting that produces glare or reflections, fuzzy images or images that are too dim or too bright;
Failure to blink often to moisten the surface of the eyes;
Use of corrective lenses that are inappropriate for the user's position and distance from the screen;
Minor visual defects such as astigmatism that might go unnoticed unless intense computer use exaggerates them.
The following steps can help alleviate your symptoms:
Lower your computer screen so that the centre of the screen is 4-8 inches below your eye level and at a viewing distance of 20-28 inches.
Use artificial tears as recommended by your doctor to re-wet and lubricate your eyes.
If you are seated in a draught or near an air vent, try to change your seating or position and direct the draught away from your eyes.
Low humidity or fumes aggravate a dry eye condition.
Concentrate on blinking whenever you begin to sense symptoms of dry or irritated eyes.
Take frequent breaks. Follow the 20-20-20 rule. This simply means every 20 minutes, look away beyond 20 feet and blink 20 times.
Red Eye
One more common eye problem that affects students and adults alike is the red eye. The most visible symptom is the redness of the eye, which could be due to fatigue and strain. Reading in poor light, lack of sleep, poor contact lens hygiene, allergies due to contact lenses, infections such as conjunctivitis, dust etc causes the red eye. By taking note and care of the above-mentioned causes, red eye can be prevented.
To conclude, if there is a prolonged discomfort from any of the eye problems or a marked change in the vision is noticed, you should immediately have your eye examined by an eye specialist. Wishing you all the very best for your exams!
