Reasons
What causes nearsightedness?
Myopia may be due to the pupil being too long or the corneal curvature being too steep. Therefore, when the light rays enter the eye, they do not fall on the eye’s sensory membrane, but fall on the front of the eye, causing the images to blur.
Possibilities
What increases my risk of being nearsighted? There are many things that can cause myopia. For example, as follows.
Family history. Myopia tends to run in family members, and if one or both of your parents have myopia, you’re more likely to have it too.
