Also called: Farsightedness, Hyperopia, Myopia, Nearsightedness
Your cornea is the clear front part of your eye. It is like a window that controls and focuses the light coming into the eye. If your cornea has an irregular shape, the light does not focus properly. Everything looks blurry. This is a refractive error.
Four common refractive errors are
- Myopia or nearsightedness – clear vision close up but blurry in the distance
- Hyperopia, or farsightedness – clear vision in the distance but blurry close-up
- Presbyopia – inability to focus close up as a result of ageing
- Astigmatism – focus problems caused by the cornea
Glasses or contact lenses can usually correct refractive errors. Laser eye surgery may also be a possibility.
So if you notice a change in your vision- suddenly you cannot see the fans in the 10th row or that the FOH sound engineer is waving at you to stop noodling on your guitar during sound check, make an appointment to see an optometrist.
