Frequently Asked Questions

What is low vision?

It’s a loss of sight that can’t be corrected with prescription eyeglasses, contact lenses, or surgery. Low vision doesn’t include complete blindness, because you will have some sight left. It can be treated or offset, however, with vision aids like magnifying glasses.

The condition includes different degrees of sight loss. You might have a blind spot or an almost complete loss of sight. The Academy of Ophthalmology divides low vision into two categories based on the vision in your best eye:

Partially sighted: Your vision is between 20/40 and 20/200 with conventional prescription lenses.

Legally blind : Your vision is no better than 20/200 with conventional correction, or you have a restricted field of vision less than 20 degrees wide.

What Are the Types of Low Vision?

The most common ones include:

Loss of central vision. You have a blind spot in the center of your field of vision.

Loss of peripheral (side) vision. You can’t see anything to either side or above or below eye level. But your central vision remains intact.

Night blindness. You don’t see well in poorly lit places like theaters or outside at night.

Blurred vision. Objects both near and far are out of focus.

Hazy vision. Your entire field of vision seems to be covered with a film or glare.

How Is Low Vision Diagnosed?

You’ll need an eye exam. Make an appointment with your eye doctor if vision troubles prevent you from daily activities like reading, travel, cooking, work, watching television, or school.

Your eye doctor will use lighting, magnifiers, and special charts to test your visual acuity, depth perception, and visual fields.
