Nearsightedness

Seeing the things surrounding us clearly, the light rays after passing through the lens of the eye should fall on a specific point above the retina, but the rays, in this case, are located in front of the retina and not above it, and because of this, an additional lens must be placed in front of the eye to help it collect the rays, and then send them To the retina and not in front of it, and this process helps to see the near images clearly, while the far ones cannot be seen clearly.

For the treatment of nearsightedness by laser, the central part of the cornea is flattened by scraping a certain degree of the central section of the cornea. As for astigmatism, it is treated by making the cornea more spherical, by removing more layers of the cornea in one part than the other.

Farsightedness
