How are power defects of the eye corrected? Do exercises or medicines have any role?
Refractive errors Myopia (Short Sight), Hypermetropia (long sight)& Astigmatism (irregular curvature of the cornea) are corrected with Spectacles, Contact Lenses and by Refractive surgery or Laser. As these defects occur due to the abnormal length or curvature of the eyeball, medicines or eye exercises have no role. However, in certain eyestrains, vitamin supplements as well as yoga, meditation & other relaxation techniques do help.
