How to take your first vision test
•
Place your elbows on a flat surface to hold your smartphone
as steady as possible.
• Hold the smartphone at reading distance, and slowly move
it closer until the eye cup of the device touches your right
eye.
• You should see two lines, one red, and one green. Take a few
seconds to find these lines. If you do not see them, try gently
moving the device left and right, up and down. It takes some
practice and is an important part of getting accurate test
results.
• Once you see the red and green lines, open and relax your
left eye (untested eye) during the test. Most people find it
helpful to focus the untested eye on a large object at least 6
feet away.
