Contact Lens Examination
Contact lens examinations, include special tests that typically are not performed in routine eye exams for eyeglasses. It allows your eye specialist to take a thorough look at the health of your eyes and the quality of your vision. It’s important to make sure that your lenses fit both your eyes and your vision properly.
Here’s what to expect:
Whether you have 6/6 (aka ‘perfect’) vision, you need regular eye exams to help keep your eyes and vision at their best. This involves:
- Eye tests to determine your refractive error and prescription
- Cover tests to check how well your eyes work together
- Slit-lamp examinations to have a magnified view of the structures in your eyes
- Ophthalmoscopy test to better exam the back of your eyes
Contact lens consultation
Your optometrist will ask you about your lifestyle and preferences. Some contact lenses may be better for athletes with active lifestyles; others may be better for frequent travelers with convenience in use. Some prefer colored lenses while others may prefer “transparent” contacts.
Your optometrist may also discuss the option of rigid gas permeable (RGP) contact lenses, which often provide sharper vision than soft lenses; and Myopia Control contacts for children and teenagers.
Pre-lens fitting measurements
Pre-lens fitting corneal scanning
The health of your cornea will be evaluated using a biomicroscope (also called a slit lamp). This lighted instrument provides a highly magnified view of the cornea and other tissues to enable your optometrist to evaluate the health of the front of your eyes.
Contact lens fitting
You will be given trial lenses to wear for a few minutes. After the initial tearing of the eye stops and the lenses stabilize, your optometrist can then make a proper evaluation of how the lenses fit with the biomicroscope. This is to ensure the alignment and movement of the lens are optimal and adequate.
In follow-up visits, your optometrist will check for defects on your cornea and make sure your contact lenses are not damaging your eye’s surface.
Usually, it takes two or three follow-up visits to complete an uncomplicated contact lens fitting. After that, you should have annual contact lens exams so your optometrist can monitor the health of your eyes.
Remember, your optometrist is your ally in making sure your eyes get what they need to stay healthy and perform at their best. Make sure you seek professional advice whenever you’re encountering or making changes involving your eyes and vision.
Bring your current contact lenses (boxes/prescription) or eyeglasses, if you have them for the session.
