How do contact lenses work?
Like lenses in glasses, contact lenses correct vision by refracting and focusing light to make up for abnormality in your eye. Contact lenses float on the tear layer covering your cornea and are designed to move with your eyes naturally. This is one of the major advantages that contact lenses have over eye glasses. Many patients choose contact lenses because they don’t like the look or feel of glasses or they prefer to have unencumbered peripheral vision.
What are the different kinds of contact lenses?
Over the years, contact lenses have come a long way. In addition to disposable soft lenses that are available in daily, biweekly, or monthly varieties, Dr. Clark offers:
- Multifocal lenses, which are similar to bifocal eyeglasses, combining prescriptions for close reading and distance vision. They are available in soft and rigid gas permeable materials.
- Keratoconus lenses, which help control keratoconus, a degenerative eye disease that can lead to the need for a cornea transplant. They are also available in soft or rigid gas permeable materials.
- Gas permeable lenses, which are made of hard plastic, so they maintain their shape and provide crisp vision. Often referred to as GPs, these lenses do not contain water and are resistant to deposits and bacteria, so you will not need to replace them as frequently as soft lenses. They are called gas permeable because they permit oxygen to pass through to the eye, which helps to protect eye health.
- Scleral lenses, which cover the entire corneal surface of your eye. These lenses accommodate corneal irregularities and provide comfort to people who suffer from dry eye syndrome because they do not disrupt the tear layer, allowing more oxygen to reach your eyes.
