You
must have heard about miniature, lens-like object fixed over the cornea for
improving vision. These are plastic-like curved lenses that are actually made
up of fiberglass and are uses as a surrogate to spectacles. These are the
contact lenses.
Let
us thrash out some essentials of using contact lenses, as they are getting
trendy among young generations these days.If you peep into the well of history, you will find that the issues of contact lenses are at a depth of about hundred years down. It was Leonard who first envisaged about using contact lens in the nineteenth century, however, his aspiration became a veracity only recently with the tribute of accomplishment being given to Sir John F W Herschel who was first to recommend it. Today, contact lenses are not only used under medical conditions but also for the purpose of fashion.
Firstly, since contact lenses come directly in contact with cornea, minimum stress is produced on the due to reduction of reflection.
Secondly, contact lenses are especially helpful to those with a greater degree of myopia because contrary to the thick glasses these lenses help eliminate effects like ‘prismatic effect’ and ‘oblique vision’.
Thirdly, when there is a great difference in the power of two eyes, the glass can cause irregularity in vision making the user uncomfortable. Contact lenses have proves to be a boon in such a situation.
Besides
myopia, there are plethora of other eye disorders where contact lens can help:
astigmatism, biopia, hypermetrophia etc
to name a few. A recent research has led to the development of telescopic contact lenses that would prove
very useful in dealing with problems like Macular degeneration.
The
biggest advantage of using contact lens is that user doesn’t have to carry
heavy spectacle on their noses. This has extended the realm of fashion for boys
and girls who suffer from certain eye disorders. They can attend all sorts of
parties and marriages without any hesitation. Most of the people wear contact
lenses for appearing cool and sexy. Most of the television actors wear contact
lenses to create special effects in a film. With colorful contact lenses, one
can increase their attractiveness and appear more charismatic to the opposite
sex!Hence, it can be said that contact lenses have come into the world as a
boon for every people.

However,
before getting a contact lens, it’s crucial to get your eyes tested by an
optometrist. Even though you’re just using it as a style factor, a qualified optometrist
will suggest the best lens for you and teach you how to fit it properly and
take care of it so as to avoid damage to the lens and eye infections. My personal experience says that contact lenses are better as compared to glasses, as it provides better field of vision and more crispiness in image. I’ve been using glasses for two years, but recently switched to contacts. It is cheaper and doesn’t make a hole in your pocket. There’s a myth in India regarding contact lenses that they are costly, but the truth is quite different. A monthly supply of ‘Baush and lomb’ contact lenses cost me around INR 350, not an extravagance for a college-going student like me. So if you’re still stuck in deciding whether to opt for glasses or contacts, I’d suggest the later.
