• Amsler grid test: All lines appear straight and unbroken with no distorted or missing areas.
• Distance vision test: All letters on the 20/20 line read correctly.
• Near vision test: You are able to read line labeled 20/20 or J-1.

What abnormal results mean:

Abnormal results may mean there is a vision problem or eye disease and that you should have a professional eye examination.

Amsler grid test: If the grid appears distorted or broken, there may be a problem with the retina.

Distance vision test: If the 20/20 line is not correctly read, it may be a sign of nearsightedness (myopia), farsightedness (hyperopia), astigmatism, or other eye abnormality.

Near vision test: Not being able to read the small type may be a sign of aging vision (presbyopia).
