Contact lenses come in a wide range of types such as prescription ones and colored ones. In fact, most forms of contact lenses only cover part of the eye in a normal way. But this is not the sole case. There is still one special type of contact lenses that covers the full eye. This extraordinary type of lenses is actually one member of the cosmetic lens category. Like other forms of cosmetic contact lenses, this type that covers the full eye does not improve eyesight in any way. They are just for people to make fun with their friends or whilst at a themed party.
Contacts that cover the full eye are called the eye contact lenses. They are different from standard lenses for vision correction and colored contact lenses. On the market, there are some brands that offer extended wear contact lenses that correct vision problems. For eye contact lenses, this can never be the case. Covering the whole eye, eye contact lenses can only be worn for several hours one time. They can not last a day long and be left in the eyes during sleeping.
Customers who want to get fun from eye contact lenses should buy customized lenses. The reason is quite simple that these lenses cover the full eye and people have different eye sizes. An appropriate pair of eye contact lenses should make the white part of the eye completely invisible. In this case, people who are considering eye contact lenses have to visit an optician to get a check about their eye sizes.
A right size is critical for eye contact lenses. Firstly, eye contact lenses with a wrong size will waste money unnecessarily. And a correct size can ensure eye safety. This is quite understandable that a pair of eye contact lenses that is not made proportionally with the wearer's eye size will easily fall out. In a serious case, it may obstruct the wearer's vision. Eye contact lenses have no special requirements on lens insertion and removal as regular lenses.
