Myopia / Near-sightedness

Myopia or near-sightedness is when distant objects appears blurry and occurs when the light rays focus in front of the retina. Treatment is with glasses, contact lenses or surgically with LASIK treatment.

Hyperopia / Far-sightedness

Hyperopia or far-sightedness is when objects close by appears blurry and occurs when light rays focus behind the retina. Treatment is with glasses, contact lenses or, depending on the degree, with LASIK treatment.


An irregular curvature of the cornea or lens (or both) results in a distorted image because light can’t focus on a single point on the retina, but has more than one focal point. Vision at all distances can be affected by Astigmatism and may be associated with either myopia or hyperopia. Normally, this can be corrected with glasses, contact lenses as well as LASIK treatment.  


Not to be confused with far-sightedness, Presbyopia occurs when the lens and muscles of the eye lose their ability to focus sharply on objects close by because of aging, making it difficult to read or see fine details up close. LASIK cannot correct this problem. With the development of technology there are new options available which include monovision.  Please consult our specialist for more info on monovision as it does not suit everyone.
