Like eyeglasses, contact lenses can now be manufactured in different styles and designs. They can be used for vision correction, cosmetic purposes, etc. Therefore, many buyers are confused by wide selection of items in the market. In fact, contact lenses can be mainly categorized into two major groups, namely, soft lenses and rigid gas permeable lenses. As their names indicate, soft series are made from water-containing materials and can bring users a lot of comfort, whereas rigid series can be used for much longer time.
Of course, both soft lenses and hard lenses can also be subcategorized into further groups. For example, all of them can be divided into other kinds from the perspective of wearing time. In the market are now daily, weekly or monthly lenses. Or there are also lenses that can be slept in.
Usually, new users of lenses might be confused about which one is for left and right eye. In fact, there are some laser imprints on the lenses, which must be carefully read. If people do not know how to read them, some guidance is needed. It is a good idea to ask for help from those regular users, who usually have a full understanding of how to tell the right from the left lenses. Of course, no great harm will be caused if lenses are wrongly inserted- lenses for left eye are inserted in the right eye.
And now, more and more contact lenses with greater merits are brought into market. For example, some new hard lenses are particularly manufactured for users who have eye dryness and other problems. And there are also lenses that can be worn for very long time without being removed- these lenses will not cause any eye infection or discomfort. Anyway, the maintenance of lenses should be highly noticed, no matter how nice or advanced these items are.
