How should I prepare for a vision test?

No special preparation is required before having vision tests. If you wear glasses or contact lenses, bring them with you to the examination since the tests cannot be properly performed without them. If you have a copy of your current eyeglass prescription, bring it with you.

Many medicines may affect the results of vision tests. Be sure to tell your health professional about all the over-the-counter and prescription medicines you take.

Talk to your health professional about any concerns you have regarding the need for vision tests, how they will be done or what the results will mean.
