- Myopia (short sight)
This is commonly known as shortsightedness. Vision is clear when focussing on objects close to, but blurred on objects far away.
The inability to see close to due to being not so young (40 - 50 years old). The lens in the eye becomes less able to focus as we get older, leading to the need for 'longer arms' when reading. Corrected by reading glasses.
When there is a difference in the prescription in the meridian of one eye to the perpendicularly opposite meridian in the same eye (rugby ball shaped corneas!).
'Lazy eye', when one eye fails to develop properly due to squint, or one eye having a much higher prescription than the other. Corrected with patches over the good eye and spectacles.
Loss of transparency of the lens in the eye. Biggest risk factor is hereditary. Age being second. Exposure to excessive sunlight. Smoking, poor diet. We are in the Coventry Direct Referral Scheme, which means that you can be referred straight to an ophthalmologist if there is a problem.

- Hypermetropia (long sight)
Commonly known as long sightedness. The eyes have to work to focus far away, and work harder to focus near to. The result is eye strain, especially close to. Children tend to be long sighted.
