People with certain vision problems can use prescription contact lenses if they do not wear prescription glasses. This is because glasses may damage wearers’ personal images; they may also bring wearers a lot of inconvenience when wearers have to do some special things. For example, many people tend to wear lenses other than glasses if they want to play sports games. If they do not wear lenses, they may give up playing. Or some people may wear glasses while working and lenses while playing. Therefore, prescription contact lenses are essential for people who want to play games or do some outdoor activities. However, these lenses must be prescribed and users should consult with their eye doctor first.
But in some cases, lenses are not ideal options, such as swimming. In this situation, the lenses may be contaminated by bacteria in the water. If people really want to wear lenses, some protective glasses or swimming goggles are also needed. Remember to keep clean of them at all time.
In fact, the prescription for lenses varies greatly from that of glasses and people should make a new prescription if they want to wear prescription lenses. Pay more attention to this, for inappropriate prescription may cause eye infection or vision damage. In addition, people should also know which types are they needed. Some are for fortnight wear; others are for much longer time. Of course, people can also choose their beloved color in the lenses, so as to make them unique in the public.
Besides, people without vision errors are also suggested to get personalized prescriptions. Therefore, it is not a good idea to purchase lenses without prescription. Especially, buying contact lenses online is not suggested.
