Contact Lenses for Anyone
Scleral lenses
Scleral lenses are a type of oxygen-permeable lenses that vault over the cornea and instead rest on the sclera or the “whites” of the eyes. The lenses are useful if your cornea has an abnormal shape and can help treat a wide variety of eye conditions, including problems like presbyopia, dry eye, keratoconus, myopia, and astigmatism.
Ortho – k / Corneal refractive therapy (CRT) lenses
Orthokeratology (Ortho-K) and corneal refractive therapy (CRT) lenses are best thought of as visual braces since they’re worn at night as you sleep. These lenses help reshape the cornea, making them a great solution for children and adults with myopia. The lenses are removed during the day, offering clear sight without the use of corrective lenses.
Multifocal Lenses
Multifocal lenses are high-tech lens that includes multiple prescriptions to cover a range of distances. Multifocal lenses excel at correcting age-related vision issues like presbyopia, where a person may need assistance seeing objects both near and far away.
Limbal Fit
Larger than traditional lenses but smaller than scleral lenses, limbal fit contacts have a relatively larger diameter that increases their stability without interfering with the eyelids.
Hybrid Contacts
Hybrid lenses consist of a hard center with a soft surrounding ring, which provides the comfort of soft contacts but the durability and visual quality of harder lenses. These specialty contact lenses are excellent for patients with astigmatism and presbyopia, or for those wary about wearing harder, more inflexible lenses.
Rigid Gas Permeable
Rigid gas permeable (RGP) lenses are hard contact lenses that are specially formulated to allow plenty of oxygen through to the eye. These lenses are more breathable than traditional soft lenses, they last longer, are more resistant to bacteria build-up, and offer a sharper vision. They have a wide range of uses and are great for patients, such as those who have corneal irregularities or dry eye disease.
