During a routine eye examination, a vision test is given. This test will tell the eye doctor exactly what prescription is needed for glasses or contact lenses. Normally, a value of 20/20 is considered perfect vision. Individuals who can read letters that are 3/8 of an inch tall from at least 20 feet away would have 20/20 vision. If an induvial does not have 20/20 vision, they have what is called a'refractive error".

What causes this refractive error?

• The light is not being reflected from the lens of the eye.

• The light is not being absorbed when it hits the lens of the eye.

• The light is not being transmitted when it passes through the lens of the eye.

• The light is not bending properly when it passes through the lens of the eye.
