Video – Eye Anatomy: The Cornea…and Contact Lenses, Degenerations and Keratoconus

Your eye is like a camera.  There are 2 structures that focus light – much like the lens of a camera.  These 2 structures are the cornea and the lens.  The cornea is the clear front surface of your eye that is located in front of the colored part of your eye (called the iris).

If you are a contact lens wearer – the contact lens sits on the cornea.  Not all corneas are the same size.  Some are more curved or “steep” and others are more “flat”.  It is important to be properly fit for contact lenses by your eye doctor.  If a contact lens is not properly fit, the contact can cause serious problems for the wearer – including corneal distortion, corneal swelling, corneal ulcers, inflammation and more.

A corneal topographer is an instument that can detect any corneal distortions caused from a contact lens.  A contact lens may look and feel “fine” but, it can still be causing problems that you may be unaware of.  Many times sleeping in your contact lenses or overwearing your contacts (wearing a 2 week contact for more than 2 weeks) can cause corneal distortions.

Cornea With Keratoconus

Cornea With Keratoconus

At Visionary Eyecare in Pembroke Pines, Sunrise and Davie- we perform a corneal topography on ALL contact lens patients. During the contact lens eye exam we use the corneal topographer to monitor the health of the patient’s cornea before fitting with a new contact lens and also to monitor the corneal health year to year for established contact lens wearers.

Corneal Topography can also detect some corneal degenerations and corneal dystrophies like keratoconus.  Typically a person with keratoconus has a lot of astigmatistm, distorted vision and possibly sensitivity to light.  The cornea starts to protrude in a “cone-like” fashion.  Most of the time a specialty contact lens can help these patients see clearer and may prevent the corneal dystrophy progression.  In advanced cases, the apex of the cornea may thin so drastically from keratoconus that a corneal transplant may be necessary.

Wild Eyes Special-Effect Halloween Contact Lenses

WildEyes special-effect contacts include these designs:
1. Icefire, 2. Wildfire, 3. Zoomin’, 4. Jaguar, 5. Zebra, 6. Cat Eye, 7. Knockout, 8. Black-out, 9. Red Hot, 10. White-out, and 11. Hypnotica.

Its time to start thinking about enhancing your Halloween costume and Wild Eyes Contact Lenses are the perfect finishing touch to any spectacular costume!  The most popular Wild Eyes color contacts around Halloween are the Cat Eye contact lenses and White-Out contact lenses (made popular by Marilyn Manson…a Florida native).

Costume contact lenses are stylish to wear and they are designed for fun but remember, that they are still medical devices that will be placed onto your eyes.  They must fit you properly and be well taken care of to keep them very clean so you don’t get any eye infections.  Contact lenses that do not fit properly or are not cleaned can cause very serious eye problems. So, it is important to remember that you need your eye doctor to accurately fit them on your eyes and give you a prescription for them.  Even if you don’t currently need wear glasses or contacts to see clearly – you still need a prescription for them to ensure they FIT your eyes properly.

Have lots of fun with your costume contact lenses but, NEVER SHARE OR SWAP these or any type of contact lenses with anyone else – this can lead to pinkeye and other potential serious eye infections that could lead to blindness!

Never buy your costume contact lenses from a place (like a Flea Market) that does not ask you for a valid prescription from your eye doctor. Some of these lenses sold in these places are not FDA approved.  You ALWAYS need a prescription from your eye doctor to ensure that the contact lenses fit you properly, feel comfortable and won’t cause you any serious eye problems.

Have FUN and BE SAFE!

Happy Halloween!!!
