The lens: a long time ago, it absolutely was a whopping, cumbersome lens of glass made to be shoved to the eye. It scratched the cornea, caused headaches, frequently broke, and was vulnerable to falling out.
Technology has come a long way, however, and these days you will find all manner of contacts, all made for different purposes plus much more convenient than their cumbersome forebears.
Among a number of other benefits, contact lenses provide sharp definition and vivid colors, which glasses sometimes simply cannot mimic. Glasses get smudged, they get cracked, and they get broken. They leave red indentations around the sides from the nose and so they gather dust in a way that seems to defy gravity. The contact, alternatively, is only prone to getting dry, but a drop or two of saline may take care of that. Moreover, where once upon a time an individual needed to maintain a pair until their prescription changed with the way glass lenses were created and because these were so expensive, now there are disposable, soft lenses. Furthermore, there's a vast array of cheap contact lenses, which makes them easily replaceable and highly affordable.
There is also the situation of colored contacts. Unlike glasses, these provide a person the chance to change his / her the color of eyes, which is something many people appreciate. Brown, amber, grey, light blue, dark blue, light green, green, purple, violet, almost every color within the spectrum can be obtained.
Because of this, even those who have 20/20 vision sometimes choose cosmetic contact lenses. These may take the form of a colored lens or they may be cosmetic contacts. Frequently, novelty and color lenses usually are not symbolic of cheap lenses, but they are not incredibly expensive. Needless to say, it truly is dependent upon what style one wants.
Anyway, a novelty lens could mean a lot of things. They could be cat's eye lenses, or they might examine snake eyes. You can find white contacts, black ones, and red ones; some have spiral designs and then any variety of other symbols. The adventurous person might wear these each day; others might use them for costume parties or Halloween festivities.
Back to cosmetic lenses, they offer people the chance to change their look from day to day. If an individual so desires, their the color of eyes could match their outfit everyday. Just because a lot of people frequently wish that they an eye color different from whatever they were born with, there is a large industry for these kind of lenses. Novelty lenses are only as common in certain scenes and cultures. For certain, however, a person who actually needs contacts to see should probably steer clear of the novelty ones. Some of them are so opaque that it is impossible to determine out of them. Exactly the same can't be said for colored lenses, that are just as translucent as clear ones.
