In the normal eye, your cornea focuses light rays directly on the retina, resulting in clear vision without correction. In myopia, or nearsightedness, your eye is longer than normal. This extra length causes light rays to culminate at a point in front of the retina (see picture).

A person with myopia normally develops it between the ages of eight and 12 years, and almost always before the age of 20. This myopic drift typically stabilizes in adulthood.

Topical and oral antibiotics are often effective treatment for chalazia. In the case of a bothersome and persistent chalazion, a simple in-office procedure can be performed to drain and excise it. When a chalazion recurs in the same part of the eyelid or has a suspicious appearance, the removed tissue is sent to a lab for analysis. Fortunately, most chalazia are relatively harmless.
