Don't Dazzle When Come To Contact Lenses Of Various Colors
Contact lenses are corrective, cosmetic or therapeutic lenses usually placed on the cornea of the eye
. They eliminate the trouble for eyeglass wearers to wear
glasses. To meet the development of fashion in today's work, the color of contacts become varied, such as purple, blue, green, pink and even black. Facing so many potions, one would very inclined to get dazzled. Which color to choose?
To know the answer, the following information should be equipped. Contact lenses can be categorized into those having transparent tints and those having opaque tints, and both of them are for people with light colored eyes while the opaque ones perform better for people with dark colored eyes.
The emergence of colored contact lenses causes the interest of people with great eyes, especially those who are young, to wear contacts, for the sake of enhancing the charm of their eyes. One thing they need to know is that, in spite that those lenses are not for vision correction, when one would like to have one, he/she is required to get a fitting process as that needed for non-tinted lenses, or eye health would be threatened. Anyhow, they are medical devices. Therefore, for the goodness of eye health, Food and Drug Administration (FAD) regulates that one is not allowed to sell any contact lenses if the buyer does not have a valid prescription, fitting, supervision, or regular check-ups by a qualified eye care professor. Not everyone is a contact lenses person, and he/she may suffer serious corneal scarring and eye infection, etc. which are likely to lead to vision impairment, and in some extreme cases, blindness is possible. Besides, conjunctivitis, corneal edema, allergic reaction, abrasion from poor lens fit, reduction in visual acuity, contrast sensitivity, and other visual complications are potential risks.
As a result, prescription is a must for one to buy contact lenses. If you do not have one, go to a professional eye hospital or eye care center, and ask for an optometry. Usually, it is free of charge.
However, no matter how strictly FDA regulates, some customers or buyer would also find a way to illegally buy or sale contact lenses without a prescription. It always happens in some beauty salons, record stores, video stores, flea markets, convenience stores, beach shops and the Internet. Therefore, it is the responsibilities of both customers and retailers to obey the rule for the sake of eye health.
