As we progress through life it is important to realise that our eyesight changes and in a lot of instances we don't even notice these changes. Conditions can often include Myopia (shortsightedness) or Hyperopia (farsightedness) and can result in eyestrain while working on computers, driving or enjoying sporting activities.
It is very important to have regular eye examinations so that any problems can be identified at an early stage and the correct remedy found. Plus you may find that you need different eyewear for certain activities such as driving, reading and certain sports such as swimming, skiing and racket sports.
