Contact Lens Exam
If you're ready to graduate from eyeglasses to contact lenses, you've probably got questions about the process of contact lens eye exams. When fitting for new contact lenses our Las Vegas eye doctor will give you a general eye exam, then do additional tests to ensure that your contact lenses will fit your eyes correctly. It's best that you have both exams at the same time, so leave extra time in your schedule for a lengthier exam.
During your eye examination for contact lenses you'll have the basic visual acuity test, using a wall-mounted eye chart, plus other tests to determine what prescription corrective lenses your eyes may need. Our Las Vegas Optometrist will also take measurements of your eyeballs to ensure you have the correct lens prescription. Using a tool call a keratometer, our doctor will measure the curve of your eye's cornea, the clear front surface. They may also use a computerized program called corneal topography to measure the entire shape of your eyeballs, in effect mapping the surface of your eye.
Once our optometrist has thoroughly tested your eyes they’ll discuss options about contact lens wear with you. Your daily lifestyle and willingness to follow daily routines make a big difference in what type of contact lenses are right for you. You may want to change your eye color with colored contact lenses, or your schedule may determine that extended wear contacts are better for you.
Soft contact lenses are the most popular type prescribed, but depending on your prescription our eye doctor may discuss rigid gas permeable lenses. These are shown to give a sharper image in the right type of patient.
Your age can affect the type of contact lenses you end up wearing. People over the age of 40 will develop a condition known as presbyopia, which makes it more difficult to read smaller print. If you work on a computer all day long you may have problems with focusing on middle distances. In both of these situations bifocal contact lenses can be the answer to your vision problems. Alternatively, you can be fitted with one contact lens designed to help you see in the distance and another designed to make close objects easier to see. If you have astigmatism you'll still be able to be fitted with contact lenses. This condition often happens later in life, and toric lenses now exist to correct this problem.
Optometrists at Drs. Kopolow and Girisgen in Las Vegas can fit you for contact lenses in a number of offices, making it convenient no matter where you live or work. Among their offices are:
