The cornea is the transparent front part of the eye or the eye’s outermost layer.
In wavefront LASIK, a special ”wavefront” sensor is used to measure the eye as the surgery is being performed.
Lasik is a type of refractive surgery for correcting accomodative disorders such as myopia, hyperopia, and astigmatism. Performed by ophthalmologists using a laser, this surgery allows the doctor to reshape corneas in order to sharpen vision.
Photorefractive Keratectomy (PRK) uses a laser to sculpt the surface of the cornea which contrasts with LASIK, which sculpts tissue deeper within the cornea, under a corneal flap.
Aspheric lenses are typically designed to give a thinner lens result than sperical lenses. They also distort the viewer’s eyes less as seen by other people, producing a better aesthetic appearance. Aspheric eyeglass lenses typically do not provide better vision than standard spherical lenses, but rather allow a thinner, flatter lens to be made without compromising the optical performance.
Polarized lenses are often used in sunglasses, instead of tinted lenses, to reduce glare from reflective surfaces such as the surface of a lake or the hood of a car. They accomplish this through a process called polarization, a filter in the lens that works much like a venetian blind controls sunlight through a window.
Anti-reflective is a type of caoting that we can apply to your lenses to help reduce glare. Adding anti-reflective treatment to lenses helps the wearer to see better out of them, as there is minimal distracting glare. This is most evident when driving at night and using glasses on the computer.
High-Index lenses refer to lenses that are made out of a thinner and lighter weight material than conventional plastic lenses.
If you have presbyopia, you can wear multifocal contacts in lieu of multifocal glasses. Multifocal contacts can give you clear vision at all viewing areas, distance through near.
Toric contact lenses are designed to be worn by people with astigmatism. Toric contacts can be found in a range of wear styles including daily, weekly, monthly, or colored contact lens.
