A revolution in Contact Lenses: Those Colored

Contact lens is a great creation

Contact lens is a great creation. It eliminates the trouble for eyeglass wearers to wear glasses and enables them to see clearly just as they have great eyes. The development of contacts undergoes a rather long way. They are originally hard ones, and then develop into soft ones, and finally disposable ones. Recently, there is another revolution. That is color contact lens. From its name, one can easily concludes that it refers to contact lenses that are tinted with different colors, ranging from blue, pink to even black. As the emergence of them, they are well received, for they can change the color of eyes to whatever color one likes. At present, when one is intended to buy a pair of contact lenses for vision correction, he/she would be advised to choose those colored. The color contact lenses are so popular that, even some people with good eyes would ask eye doctors to prescribe them a pair of non-prescription color contact lenses.

Like ordinary contact lenses, those colored are available in hard, soft and disposable ones. Among the three, soft color contacts are of the great popularity, because they are softer so that eyes are not so likely to get damaged. They are made of various types of polymers, usually containing some variant of silicone hydrogel. Water absorbing materials are usually applied in the soft contact lens production, as a result, oxygen is more likely for eyes to reach the cornea and the lens would be more comfortable to wear. Disposable color contacts are used in a large scope as well. They enable wearers to change their eye color as often as they want, and even everyday.

As mentioned above, color contact lenses are both for vision correction and ornament. Therefore, some contacts which would present scary appearances exist as well. They can be black out contacts, glow in the dark contacts and black sclera contact lenses. They are rather useful for Halloween party.

Anyhow, contact lenses are medical treatment, therefore, FDA regulates that eye doctors are allowed to prescribe any contacts for anyone if he/she doesn't have a prescription, or the wearers would probably suffer from eye infections, ulcers and other complications that are not present with glasses. When color contacts are fitted to the eye, much more is taken into account than many people are aware of. The best advice is to follow doctor's instruction for the sake of eye health.
