Causes and Trigger factors of low vision Far
In normal conditions, the cornea or lens of the eye has a shape and a smooth surface so that the incoming light is bias could be focused on the retina. But another case with people with low vision.

Laser epithelial keratomileusis (LASEK), laser keratectomy in situ (LASIK) photo refractive keratectomy, and (PRK) are three types of laser surgery can be an option.After undergoing LASIK, LASEK or ability of your eyes will be back in 24 to 48 hours.But the recovery in total generally take up to a month.
