What is what prescription is legally blind?

Legally blind is a term used to describe a level of vision impairment that has been defined by law to determine eligibility for certain benefits and services. It's important to note that being legally blind doesn't necessarily mean complete blindness.

The legal definition of blindness generally hinges on two factors:

• Visual Acuity: This refers to the sharpness or clarity of vision. Someone is typically considered legally blind if their best-corrected visual acuity is 20/200 or worse in their better eye. This means that even with glasses or contact lenses, they can only see at 20 feet what a person with normal vision can see at 200 feet.

• Visual Field: This refers to the width of the area a person can see when looking straight ahead. Someone can also be considered legally blind if their visual field is 20 degrees or less in their better eye. This means they have a very narrow field of vision, often described as tunnel vision.

It is possible to be legally blind in one eye only. The standards for legal blindness apply to the "better eye".
