A New
Hope for Astigmatism: Toric Contact Lens
Even though how complex the explanation of
astigmatism is even when discussed even without it finer details,
in laymen’s terms, the cure for such remains relatively simple. By
the use of Toric contact lens.
Astigmatism is a common affliction, and has the
widest range. Some sufferers will have no trouble focusing on
nearby fine details but won’t notice the loss of depth at farther
instances. It even goes so far; as far as when normal individuals
would be surprised upon finding that the fitted glasses are clearer
than their ‘normal’ vision. These individuals are sufferers of
astigmatism, albeit low key.
Astigmatism is a refractive eye error, a
condition wherein the eye cannot identify the correct degree of
refraction along different meridians. Heightened astigmatism will
have trouble focusing on finer details and can curtail
accommodation eye powers, while also experiencing eye fatigue,
headache and Asthenopia.
The known treatment, toric contact
lens accommodates this eye disorder by presenting a
correcting curvature before the eye. A means is made to ensure
that, like the bipolar contact lens, it stays in place even when
the eye blinks. Because fitting a patient with toric contact lenses
involves a lengthy procedure in testing the eye condition (through
a specialized one eye slide machine), acquiring toric contact
lenses are way more expensive than most corrective contact lens.
And these toric contact lenses, apart from the eventual doctor’s
fee and the consultation process, are made more costly with
specialized manufacture of the lens.
Toric contact lenses could be either soft
contact lenses or rigid gas permeable (RGP). Soft contact lenses
are a comfortable wear though for conditions like astigmatism, it
is best to wear the rigid gas permeable type of contact lenses. RGP
types of lens also compel the cornea to conform to the shape
presented by the contact lens, therefore there is more probability
of success than with the softer ones. However, rigid gas permeable
lenses are known to be very uncomfortable, requiring a period of
time for getting accustomed before the lens can be enjoyed.
While toric contact lenses, due to their
complexity in fitting and relatively harder to obtain (as
specifications are often singular), are mostly non disposable, long
term use, some well known brands have designed toric contact lenses
that is intended for everyday disposable use. There are even
colored varieties offered over the internet. The only down fact is
it cost variably higher.
In a nutshell, toric contact
lenses are prescription lenses for sufferers of
astigmatism. While online contact lens retailer can provide contact
lens regardless of your location, you still have to provide
specifications of the lens which can only be prescribed by an eye
specialist.
