A website has offered a list of symptoms which demonstrate a need for vision correction such as contact lenses or glasses.
People who can clearly see objects up close but not far away may have myopia, or short-sightedness, an article provided by sterlingoptical.com on news-medical.net explains.
Conversely, sufferers of far-sightedness, or hyperobia, can focus on far away objects but not close ones.
They may also blink a lot or experience eye strain and headaches.
If your eyes water or become tired, or you find it difficult to work at a computer, you may have astigmatism.
Such vision problems can be corrected by wearing contact lenses such as Acuvue Dailies or Focus Dailies.
The belief that contact lenses cannot correct astigmatism has been refuted by Acuvue, which itself produces lenses for this particular problem.
Acuvue says that its contact lenses for astigmatism include accelerated stabilisation design, which helps lenses to be properly aligned every time the wearer blinks.
