Contact Lens Exams in San Antonio and Castle Hills
When you're ready to move from eyeglasses to contact lenses, you'll need to come to our office for a new contact lens exam. At Vision Source Castle Hills, our San Antonio optometrist offers a wide variety of contact lens types, and prescribing the right lens for your eyes begins with eye exams. This includes specialty tests that aren't normally part of an eye examination, so make sure to let our team know that you're looking for contact lenses when you make your appointment.
Eye Exams with Our Optometrist in San Antonio
The beginning of every contact lens exam will seem familiar to you. Our optometrist in San Antonio, Dr. Raul Trevino, starts with the same examination you will experience for eyeglasses. He'll use a phoropter and an eye chart to determine the prescription needed to correct your eyes to normal vision, as well as looking for your eyes' ability to track together and work independently.
After he determines the prescription your eyes need, Dr. Trevino will use drops to dilate your eyes. This will allow him to look inside your eyes easier. A number of eye diseases can be diagnosed before you notice any symptoms, so an eye health exam is an important part of your regular eye checkup. Our doctor will be looking for such diseases as:
- Macular degeneration
- Diabetic retinopathy
If we find any early signs of eye disease during the examination, our doctor will advise you on how to proceed to minimize the damage and progression in your eyes.
What to Expect for a Contact Lens Exam in Castle Hills
Once the traditional eye exam is finished, our doctor will move on to a contact lens exam in Castle Hills. Contact lenses are custom made to fit your eyes, so we need to find the right size and shape for the perfect fit. Our doctor will use an instrument called a keratometer to measure the curvature of your cornea, the front of your eyeball. He'll also measure the size of your pupil and iris to make sure the lens is large enough to cover the front of your eye.
Once our San Antonio eye doctor is finished with your eye measurements, he'll sit down and consult with you about the right kind of contact lenses for your prescription and lifestyle. You may choose from disposable daily wear contacts, lenses that you wear and take out every night, extended wear lenses that you can sleep in for weeks at a time or even rigid gas permeable lenses that give a crystal clear view with a different lens form. You may even decide to go with colored contacts to enhance or change the color of your eyes.
