It is true that most contact lenses are mainly used for vision correction. But there are still some lenses that can be used for entertainment and cosmetic purposes they are usually called non prescription lenses. However, not all people know well of these lenses- some people may think these lenses refer to eye wear that can be purchased without prescription. This is a great mistake.
In fact, non prescription lenses refer to lenses without prescription and they must be purchased according to prescription made by licensed eye doctors all are required by FDA.
The reason why prescription is still needed can be explained like this: prescription here refers not only to the power of lenses, but also the size, the shape and other aspects of eyes. People's eyes vary a lot in many aspects. Only those lenses made according to personalized prescription can offer comfort and vision safety.
Due to their specialty in enhancing or changing users' personal images, these non corrective lenses become more popular than ever before. Some of them can be used to deepen user's natural eye color; others offer completely different eye colors. In particular, some of these decorative lenses can be designed in the color of animal eyes and so on they are ideal options for people who often attend special parties.
And now, all these decorative lenses can be easily gained from certain stores, like optical stores. But there are also some online shops offering guaranteed quality non prescription lenses. Keep in mind, eye exam and eye doctors' suggestions are essential.
