Things to know about contact lenses before using them
Contact lenses are vision correction devices that are curved and thin and crafted on tear films. They can cover the surface of your eyes. Typically, contact lenses are clear; however, slight color or pigment is added to them to make them easier to handle.
If you do not want to wear a heavy frame of spectacles, you can upgrade to contact lenses. Keep in mind the following things while choosing the contact lenses you want to use.
What are the different types of contact lenses?
Contact lenses are primarily categorized into five types based on their form factors:
- Rigid lenses: These were the first plastic-based contact lenses developed during 1940. The plastics used in the development of this type of contact lenses are based on polymethyl methacrylate. Since this was made of plastic, the passing of oxygen was an issue. However, in 1970, a rigid permeable lens was designed to resolve this problem. The rigid lenses are light and easy to wear.
- Soft contact lenses: During the year 1970 itself, a softer version of contact lenses was developed from a plastic material called hydroxyethyl methacrylate. These type of contact lenses are capable of absorbing water and easily fit over the cornea. This was a landmark innovation in the contact lenses technology, and it pushed for further innovations.
- Disposable contact lenses: Further research and innovation in the contact lenses technology resulted in disposable contact lenses during the late 1980s. Disposable contact lenses are very soft and convenient to wear. You can wear this type of contact lenses for a certain period, such as a week, month, or a quarter, based on the type of design. Daily disposable contact lenses are also available.
- Silicone lenses: Silicone lenses are comparatively a new innovation made from silicon-based plastics. These contact lenses allow more oxygen to the cornea and help in keeping the eyes airy and healthy. Silicon-based plastics are wettable and do not dry quickly, also helping avoid dry eye and irritation due to it.
- Scleral lenses: This is one of the advanced innovations in contact lenses. Computer-aided technologies are involved in the design and production of this type of contact lenses. Due to this, scleral lenses are highly comfortable and popular.
