Verified answer
☸hey friend ☸Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causeslight rays to focus at a point in front of the retina, rather than directly on its surface. ... In some cases, myopia is due to a combination of these factors.
