Why You Need a Contact Lens Exam Even If You Wear Glasses
Thinking about trying contact lenses, or ordering another box of your usual brand? A contact lens exam helps determine whether your lenses suit your eyes, prescription, and daily routine. Even when your glasses still work well, your contact lenses need their own assessment.
Why a glasses prescription is only the starting point
Glasses sit in front of your eyes. Contact lenses sit directly on the eye surface, so the prescription strength is only part of the decision. Lens material, size, curvature, and fit also matter. A lens that seems comfortable initially may still need adjustment after your optometrist checks how it sits and moves on your eye. [1, 2]
What happens during a contact lens exam
Your optometrist reviews your vision needs, eye health, and wearing habits. Explain whether you want contacts for everyday wear, exercise, or occasional use. Mention dryness, redness, changing vision, and any difficulty handling your current lenses. Trial lenses may be used to check fit and vision before the final lens choice is made. [1, 2]
First-time wearers also need practical instruction in inserting, removing, and caring for their lenses. Follow the recommended wearing and replacement schedule, and attend any requested follow-up so the fit and eye surface can be reassessed. [3]
What to bring and ask
Bring your current glasses and, if you already wear contacts, the lens packaging or a photo showing the brand and prescription. Bring the name of your cleaning solution. Ask the clinic whether to wear your lenses to the visit. It helps to describe when discomfort starts, such as after several hours at work or only in one eye.
Habits that protect your eyes
Wash and dry your hands before handling lenses. Keep lenses away from tap water, and remove them before showering or swimming. Do not sleep in them unless your eye care professional specifically directs it. Use the recommended care system and fresh solution for reusable lenses. Keep backup glasses available. [3]
Remove your lenses and seek prompt eye care for pain, marked redness, light sensitivity, or sudden blurred vision. Do not resume wear until your eye care professional advises you. [4]
