How a Contact Lens Exam Works

The goal of a contact lens exam is to understand the exact size and curvature of your eyes. As this is unique to everyone, your provider will need to run various tests to determine the right fit.

These tests aim to measure the following:

Pupil or Iris Size

Providers can determine the type of contact lenses that are right for you by measuring your eye’s pupil or iris. This simple test involves placing a card next to your eye displaying different pupil sizes and trying to find the closest match.

Cornea Size and Curvature

This test helps providers understand the proper size and base curve for your contact lenses. They accomplish this by using a device called a keratometer, which measures how light reflects off your cornea. For a more detailed look, many doctors utilize another instrument called a corneal topographer.

Tear Film

Providers must check your tear film to determine if your eyes can handle contact lenses. Some people experience dry eyes when wearing these products, which makes eyes itchy and uncomfortable.

This test works by placing a special piece of paper under your eyelid and having you close your eyes for five minutes. During this time, your tears will collect on the paper.

Contact lenses can drastically change your life. To schedule your next contact lens exam, contact Nova Vision Center today! We have the most dependableeye doctor in Falls Church, VA.
