Vision Correction: Contact Lenses
There are a number of reasons why you might prefer contact lenses to standard eyewear: a glasses-free look, hassle-free vision correction, wearing non-prescription sunwear and goggles and the convenience of never having to worry about misplacing your glasses. If you have a high prescription or astigmatism, contact lenses may provide improved vision. Today, you can even replace your bifocal glasses with bifocal contact lenses.
Your doctor will recommend the best contact lenses for your eyes based on a complete eye examination and a review of your visual needs both at work and play. Success with contact lenses depends upon a certain amount of motivation and a commitment on your part. You must learn to take proper care of both the lenses and your eyes.
Good candidates for contact lenses will possess the following characteristics:
- Realistic expectations about contact lens wear
- The ability to follow directions on the regular care and cleaning of contact lenses
- A prescription that lends itself to contact lenses
- No eye health problems
