What Happens During an Eye Exam?

A comprehensive eye exam typically consists of several tests designed to evaluate your vision and detect any potential issues with your eyes. Usually, these tests include a refraction test to check for near or farsightedness, a tonometry test which looks at the pressure inside the eye, a visual acuity test to assess how well you can see with or without glasses/contacts, a slit lamp examination to check for signs of infection or other issues, and possibly further testing if needed. All of these tests may be difficult to conduct correctly if you have contacts on them—they can impede the accuracy of the results or even cause permanent damage if left in during certain tests.

Why Is It Important To Take Out Your Contact Lenses First?

When it comes to wearing contact lenses during an eye exam, there are several reasons why they should not be worn: they can physically interfere with some of the tests; they may affect the accuracy of certain readings; some equipment used might release ultraviolet radiation that could damage contact lenses; and if left in too long there is the potential risk of corneal burns or other serious complications that could result in permanent loss of vision. So even though it’s inconvenient to take them out beforehand, it’s essential that you do so in order to get accurate results from your exam and ensure proper care for your eyes.



Before coming into your next eye exam, make sure you take out your contact lenses! Not only will this help ensure accurate results from all the tests conducted during the assessment, but more importantly it will help protect your eyes from any potential harm caused by leaving them in too long. With proper preparation and care, you can have peace of mind knowing that your eye health is in good hands!
