Arranging a home eye examination You can arrange for an optometrist to visit your home to carry out, as far as possible, a full eye examination. You can contact your usual optician to find out if they can visit you at home.

There are 3 vision tests that can be done at home: Amsler grid, distance vision, and near vision testing. This test helps detect macular degeneration. This is a disease that causes blurred vision, distorted vision, or blank spots in the vision. If you normally wear glasses for reading, wear them for this test.

The GlassesUSA Prescription Scanner is a free app that uses your smartphone camera to scan your current eyeglasses and read the prescription. You'll also submit a selfie photo to measure your pupillary distance (PD), the distance between your pupils.

Based on Opternative's own clinical study, the results of the online refractive test are just as accurate as a traditional exam and only use technology that has already been approved by the U.S. Food and Drug Administration.
