What prescription is considered severe myopia?

What is High Myopia? Doctors generally define high myopia as nearsightedness of -6 diopters or higher, according to the American Association for Pediatric Ophthalmology & Strabismus. The Association also notes that high myopia often occurs in people with very long eyes, and typically appears during early childhood.

What is considered a high eye prescription?

A high-index lens may be recommended if your optical prescription is above 2.00 diopters. High-index lenses have a refractive index above 1.50— ranging from 1.53 to 1.74. The image below compares the lens thickness of a regular plastic lens (1.50) to the most commonly prescribed high-index lenses.

What is considered severe astigmatism?

75 and 2 diopters is considered mild astigmatism. Between 2 and 4 diopters is moderate astigmatism, and 4 or more diopters is considered significant or “bad” astigmatism. Generally, eyes with 1.5 diopters of astigmatism or more require correction.

How bad is my myopia?
