The eye is one of the most important, sensitive and complex sensory organs in the human body. It allows you to gather information about the world and experience its colours and beauty. If your vision is impaired due to disease or the natural aging process, it has a direct impact on your quality of life and can be very frustrating. The most common vision impairment is a cataract. Learn more about this and other vision disorders on the following pages.
The human eye consists of different parts. The light enters the eye and travels through the front, inner and back parts of it. From there, the optic nerve carries the information further to the brain.
Refractive errors are vision impairments resulting from light not being properly refracted (focused) onto the back of the eye. This leads to blurry or distorted vision, which can be treated easily.
Like most things, the eye is not able to keep up perfect performance forever. The most common age-related changes are cataracts and presbyopia. This can affect almost everyone sooner or later.
