Toric contact lenses are similar to the normal contact lenses in
their structure. They are generally soft like the normal lenses as
well as they come in the RGP form also. It stands for ‘Rigid
Gas Permeable’ lenses that are made up of breathable plastic which
fits the corneal shape very aptly. RGPs succeed hard lenses which are
now out of fashion. The design of the lens being the only
difference.
Toric contact
lenses possess two powers, having curvatures at different angular
placements-one serving the cause of astigmatism, while the other for
myopia.
The toric lenses are very stable and impart the comfort in the
eyes since blinking or looking around don’t make these contact
lenses rotate in eyes. Again the fitting of a toric contact lenses
takes a good deal of expertise and the eye practitioner has to spend
a considerable time on fitting it.
At the same time
use of toric lenses is an expensive affair as compared to the regular
contact lenses. Torics are costlier than the spherical lenses. One
can choose the lens with most amiable features for a particular set
of eyes. One has an option of choosing toric lenses from the various
brands available in the market.
It is seen that
there are lenses that can be used for a duration of 30 days, while
there are models that need frequent replacement, and disposed after
certain period of time. Even there are lenses that can be disposed
daily.
Torics also form
a part of fashion statement, as they can be used to change eye color
or can be used to enhance the natural eye color with beauty. Eye
practitioners advocate use of multi focal torics to correct
presbyopia. Multi-focal toric contact lenses are usually non
disposable. Its important to visit a deft eye practitioner if one is
willing to have a toric lens fitted. A good eye practitioner can
suggest suitable lens design and can correctly predict eye care
needs.
