When deciding whether to wear contact lenses to an eye exam, it’s important to consider several key points. Generally, most eye care professionals recommend that you remove your contact lenses before an examination, especially if your exam involves determining your refractive error or assessing the overall health of your eyes. Wearing contacts during the exam can temporarily alter the shape of your cornea, potentially affecting the accuracy of your prescription measurement. This is particularly true if you wear rigid gas-permeable lenses or extended-wear contacts, which can cause corneal warping.

Daily disposable lenses tend to have less impact on corneal shape, but it’s still best practice to take them out at least a few hours—sometimes even days—before the appointment, as advised by your eye doctor. This ensures that your cornea returns to its natural shape for an accurate assessment. Informing your eye care professional about your contact lens usage is crucial because they might schedule extra time or suggest a specific preparation routine before the exam.

If you normally wear glasses, bringing them along and even wearing them to the appointment is often recommended, especially if you have recently switched between glasses and contacts. Arriving with uncorrected vision might be useful in some cases, but usually the eye doctor will want to examine your eyes without any correction first, then test with and without your lenses to get comprehensive results.

Ultimately, your unique vision history and contact lens type will guide the best approach. Communicate openly with your eye care provider—they’re best equipped to tailor the exam for your needs and ensure both your prescription and eye health are accurately evaluated.
