Will sitting too close to the television set hurt my childs eyes?
No, there is no scientific evidence that TV sets emit rays that are harmful to the eyes.
Why have I gradually found it harder to read without glasses?
The ability to focus on near objects decreases steadily with age and is referred to as presbyopia. Presbyopia is a natural aging of the lens. It is usually near the age of 40, when glasses or bifocals are prescribed to correct this condition.
