I use the computer extensively. Does computer radiation exist? Should I be worried about blue light?

With the increased use of computer screens, there is a growing fear that blue light emitted from these electronic devices can cause dryness of the eyes, sleep disturbances and eyestrain. This is what can be referred to as digital eyestrain. Blue light glasses representatives have claimed that this can damage the central part of the retina called the macula. At present there is no evidence of this. Radiation from a computer has never been shown to cause eye problems. Long hours staring at digital screens can cause eyestrain, and decreased blinking associated with computer use can cause dry eyes. Many eye symptoms caused by computer use are only temporary and will lessen after you stop using the computer. Getting regular comprehensive eye exams from an ophthalmologist is critical to diagnosing any potential eye disease in its early stages.

I have a misaligned eye. Can it be corrected at any age?

Misaligned eyes or strabismus can be seen at any age right from a baby who is few weeks old to a more mature individual. Usually it is seen because of the eye’s inability to function properly. The misaligned eye may be turned inwards (esotropic) or outwards (exotropic) and usually one eye is affected. In children, it may be due to a need for glasses or they may have pathology in the front or at the back of the eye. There is a misperception that it is normal for a child’s eye to go inwards or outwards when they are few months old, this is absolutely incorrect. It is important to correct the alignment soon so the child can use both the eyes together which promotes the development of 3D vision or in depth perception. Adults who are esotropic (ocular deviation is towards the nose) have a reduced field of vision on the side of the deviated eye. In adults the misalignment can be acute which represents a serious health problem or may exist since childhood but was never corrected. In the latter case it is important to see an ophthalmologist soon as this could be a sign of a nerve palsy or a stroke. Newer microsurgical techniques allow for misaligned eyes to be corrected by a simple surgical procedure, with the highest success rates.
