About Toric Lenses

Jun 12th 2015 at 7:54 AM

A Toric lens is a contact lens that looks like a slice of donnut. Word Toric is derived from "Torus" geometrical in shape, like a donnut. These lenses are also used in eyeglasses. Mainly it's shape creates different focal and refractive powers which gives visual clarity, these are used to correct different types and levels of astigmatism. They are not used by people with mild astigmatism.

Many people have some degree of astigmatism. Only patients who tried and are not satisfied with the results of regular contact lenses tend to lean towards using toric lenses because of their cost. There are many types of toric lenses. They come in different textures, designs and colours to fit your eyes and lifestyle and budget. They are made of both soft and rigid gas-permeable materials. They are made either of a hydrogel or highly breathable silicone hydrogel. Toric lenses tend to shift from their place because of its unique design, causing discomfort and poor vision in some patients.

Since these lenses have to remain in place for best visual clarity, individual fittings for toric lenses are more critical than any other contact lenses. Toric lenses come in both disposable and non-disposable designs with multifocal capabilities. Toric disposable lenses are more convenient than the other contact lenses because they don't need cleaning solutions or carry cases. They come in many colours and can be daily disposables or 30-day disposables.

 

Multifocals are non-disposables. They also come in few colours and are used to correct Presbyopia, also called "oldsightedness".Toric lenses are rejected by few patients because of the misfitting of the lenses. They take more expertise than fitting a regular contact lenses. Patients with light sensitivity have problems with toric lenses. Toric lenses will be more popular in the market of contact lenses if they are covered more for fittings, exams and cost of the lenses in their health plan.
