Long sightedness , what is it?

People who are long sighted have their point of focus beyond the horizon and so glasses are needed both for distance and reading. Below the age of 45 we are able to adjust the focus of our eye by a process called accommodation. For this reason some people who are longsighted only realise when they are in their 30s as their ability to accommodate has begun to reduce. Because the eye is too short for the focus point of the retina, glasses with a lens to bend the light inwards (convex) are needed.
