All lenses can be divided into groups depending on material they're made from, their wearing schedule, design of lenses, their purpose, and their degree of a transparency.

Contact lens materials

Contact lenses can be distinguished by material they are made of. To start, they are divided into two major groups - rigid and soft.

Rigid lenses are, in turn, divided into rigid gas-tight and more modern rigid gas-permeable.

All soft lenses are gas-permeable to a certain degree, and can be categorized further by amount of water in material. They can have a low moisture content (less than 50 percent) or a high moisture content (more than 50 percent).

Contact lenses wearing schedule

Contact lenses can also be divided by how often they should be replaced.

Do color lenses really change your eye color and look natural?

This is a question that worries most people who want to try color contacts for first time. After all, you want people to think “what gorgeous eyes she has” not “what nice contact lenses she wears”.

Color lens manufacturers are aware of issue and try to make color contacts look vivid, yet natural. There is a lot of sophisticated technology involved in brand name color contacts like Acuvue 2 Colors or Freshlook. The lens isn’t just solid color, it has a pattern similar to pattern of a human eye. Also color isn’t consistent throughout lens, just like in most people eyes. See color contact lens comparison

Color lens choices for light eyes

Depending on effect you want to create, people with light eyes can wear enhancement or opaque color contacts. If you just want to enhance your natural color, half transparent, enhancement lenses would be great for you. The best choices are:

Freshlook Dimensions - unique lens design makes your eyes appear not only brighter but also creates impression of depth and dimension.

If you feel adventurous and want a dramatic change, go for opaque lenses:

If it is your first time with color contact lenses and you aren’t sure what effect you want, start with enhancement lenses. This way your friends will notice that you look more appealing, but they probably won’t notice what it is about you that attracts their attention.

Color contact lenses for dark eyes

If you have very dark eyes and tried color contact lenses a few years ago, you probably were not very impressed with effect. Contacts of previous generation didn’t look quite right. However, recently developed color lenses like Freshlook Colorblends can do wonders for dark eyes.

One thing to remember, however, is that enhancers don’t work on brown eyes, so your only choice is opaque contact lenses. Acuvue 2 Colors opaques and Freshlook Colorblends work best for dark eyes.
