Wear Length and Are Contact Lenses Safe?
The amount of time you can spend wearing a contact lens also significantly affects the cost. You can wear some lenses for only a day, and some for a few days. Let us take a look at some options:
- Extended wear: You can use extended wear lenses for at least 6 days. You don’t need to remove this type of lens when going to bed including during sleep. Certain lenses can remain in the eyes for 30 days without causing any harm. Some lenses may also have a wear period of up to 30 days. Extended wear lenses are usually made of soft plastics that permit the flow of oxygen [5] to the eyes.
- Daily wear: You can get rid of these types of lenses after usage. Daily wear lenses must be removed at the end of each day. A new lens is reinserted every day.
According to research, more than 45 million people wear contact lenses. While they may not be compatible with everyone, they are safe and easy to use. Several complications are associated with contact lenses. For example, an eye infection [6] may occur if the lens is not properly taken care of.
It is important to get a prescribed contact lens from a professional ophthalmologist or optometrist. An eye doctor will examine your eyes to know the type of lens that suits you. In some countries, the usage of decorative and cosmetics contact lenses is illegal.
