What is a Cataract?

As can be seen from the picture, visual information in the form of visible light travels through several structure in the eye before it lands on the retina where it is processed and sent to the brain via the optic nerve. Light can be blocked, diverted, absorbed, or scattered at any point through its travel, from the cornea to the natural lens, vitreous gel, retina, or optic nerve and beyond. A cataract is clouding of the natural lens inside the eye that blocks the transmission of light to the back of the eyeSymptoms include blurry vision, glare/halos, color changes, rapid change in glasses prescription.
