Specialty Contact Lenses Fitting And Assessment
Specialty lenses serve a special purpose and not all optometrists arequalified to fit these lenses. At Eye Braces Clinic, we are trained and certified tofit a range of specialty lenses.
TYPES OF SPECIALTY CONTACT LENSES
Diseases such as keratoconus and pellucid marginal degeneration, accidents or failedLASIK procedure can cause the cornea to misshapen. Many of these patientslose the ability to drive due to poor vision.
Scleral contact lenses are used to resurface an eye. They are large-diameter lenses specially designed to vault over the entire irregular corneal surface and provide a smooth optical surface for vision correction, allowing patients to regain good eyesight.
Custom Design Rigid Lens
Rigid gas permeable (RGP) lenses are firm and retain their shape, providing exceptionallysharp vision compared to soft lenses. They are also very durable and long-lasting.
As RGP lenses are firm, it is important to custom design based on the map of your eyes in order to get a good fit. This prevents the lenses from moving out of place when worn during sports and other activities, or drop when you blink.
Multifocal contact lenses have multiple lens powers that correct vision at varying distances fromthe wearer – near, intermediate and distant zones. This all-in-one lens helps those with presbyopia correct age-related vision problems when the eye can no longer focus on objects up close.
Multifocal contact lenses are designed with a gradual transition between a prescription for close reading on one end and a prescription for normal distance viewing on the other.They are very similar to progressive eyeglasses. Bifocals, on the other hand, have a sharpedge between the near and far vision prescription areas of the lens.
Prosthetic lenses are custom-painted soft lenses prescribed to mask flaws and restore the appearance of an eye which may be disfigured due to an accident, birth defect or eye diseases.Our optometrists are able to customise prosthetic lens that are designed tomatch the appearance of the other healthy eye.
Besides providing a natural appearance to a disfigured eye, prosthetic lenses can also bemade with a prescription to correct myopia, farsightedness and astigmatism. Special prosthetic lenses can also serve the purpose of blocking excess light from reaching the back of theinjured eye to reduce glare and increase comfort.
