Myopia – short-sightedness
Myopia occurs when the eye is too long or the cornea at the front of the eye is too steep or a combination of both.
This results in light being focused before the retina instead of on the retina.
Leading to distance vision to be blurred but near vision is usually unaffected. It is first noticed at childhood when at school or adolescence.
Glasses may need to be worn all the time or part-time depending on how much the vision is affected.
