Pseudo-myopia is defined as a temporary, non-continuous change in the refractive ability of the eye, the image of an object when viewed will converge in front of the retina like true myopia. This phenomenon is explained by transient contraction of the ciliary body, which increases the refractive power of the eye.
2. Classification of pseudo-myopia
Temporary refractive error or nearsightedness is divided into two types: organic pseudo-myopia or functional pseudo-myopia.
The entity form occurs due to overstimulation of the parasympathetic nervous system. The mechanical form occurs as a result of visual fatigue or temporary eye discomfort. Both types of these false myopia are very common in people who often work for too long, require a lot of eye adjustment or students during stressful exam preparation time.
