Eye Conditions
Not all people's eyes work the same. Because of an eye condition or an accident, some people see in different ways.
Here are some of the most common vision impairments and how they affect vision.
Full sight
A person with full sight sees a scene like this.
Myopia
A person who is severely short sighted might see the same scene this way.
Macular Degeneration
Some people have a large spot in the centre of their vision and can only see around it.
Glaucoma
This is often called tunnel vision which allows a person to see with the centre of their eye but not the outside.
Cataract
This is what the scene looks like when a person has a cataract, which is a cloudiness over the lens in their eyes.
Diabetic Retinopathy
Sometimes people have damaged blood vessels in their eyes and they see like this.
Detached Retina
In some cases the retina at the back of the eye can become detached and doesn't allow a person to see clearly.
Blindness
Many people think blindness is black. It is not. There are varying degrees of blindness and most people we call legally blind have some form of vision. Sometimes this means they can see shapes but not detail.
