Low Myopia is short-sightedness in the range of -3 dpt or below. Most people who develop Myopia throughout their lifetimes are prescribed with glasses in the Low Myopia range initially at around -1 dpt after experiencing [[Pseudomyopia]].

The same basic principles for reversing [[Lens-induced myopia]] apply for all ranges of Myopia, however below -2 to -1.5 dpt usually no glasses are needed for [[close-up]] work. This means that improvement might slow down because positive [[stimulus]] can only come from [[Distance Vision]], unless [[plus lenses]] are used.

===Very low myopia===
Instead of reducing from -1.5, -1.25, or -1 (based on personal preference), the current EM strategy is to alternate zero and normalized correction, which is a variation of [[zero diopter reset]].
 
==Moderate Myopia==
Definitions vary, but -2 or -3 to -5 or -6 is considered moderate myopia.


==High Myopia==
==High Myopia==
Definitions vary, but more than -5 or -6 diopters is considered high myopia.  This category has a higher risk of various eye diseases and should be particularly regular about getting exams from an [[optometrist]] or ophthalmologist.

If your myopia is even worse, see the [[severe myopia]] page for guidance.


Very few people have high myopia for genetic reasons. Most people who have high myopia had gradually-increasing [[lens-induced myopia]].
