Some optometrists would hesitate to recommend or prescribe specialty contacts because most people are not really familiar with it. Read on to find out some information about these types of contact lenses.
Specialty Contacts are Recommended for People with Astigmatism and Presbyopia
If you are diagnosed with astigmatism or presbyopia, then you need to wear specialty contacts, which your eye specialist will normally prescribe for you. For patients suffering from astigmatism, the specialty contact lenses that are being prescribed are called the toric lenses, which have a greater power to bend light going to one direction or another. After some tests, your optometrist will ask you to decide which toric lens you would prefer to wear.
Presbyopes Patient Could Benefit from Specialty Contact Lenses
Almost half of the population of the young people in Canada requires vision correction, and most of them would prefer wearing contact lenses than the usual eyeglasses. Many presbyopes patient could benefit from specialty contacts like multifocal lenses, although the monovision specialty contact lens is still the most sought-after presbyopic contact lens.
Rigid Gas Permeable (GP) Contact Lenses
Majority of specialty contacts, are soft toric and soft multifocal contact lenses. Another type of specialty lens fitting is the rigid gas permeable (GP) contact lens. The rigid gas permeable bifocal and multifocal contacts are known to provide an excellent optical correction. This is because the rigid, spherical anterior refractive surface of the GP lens allows tears to create an optical bridge in between the contact lens and the cornea, which provides ultimate optical correction.
