There are many different types of contact lenses available when you visit your local optometrist. Your eye doctor may make a recommendation about which type is best for your particular situation, but it’s good to know what types are available.
According to the Food and Drug Administration, there are two different types of contact lenses and there are two subgroups.
Soft Contact Lenses
These are some of the most common contact lenses available and are made of a soft, flexible plastic that allows oxygen to easily pass through the lens and into the eye. These lenses are comfortable and easy to adjust, but there is also a higher risk of tearing. They are also more prone to calcium buildup over time.
Rigid Gas Permeable (RGP) Contact Lenses
If you want the best clarity, then RGP lenses are the best. They are more durable and last longer than soft contact lenses. According to the American Optometric Association, they can slip off center from the eye and allow debris to get under the lens. This makes them difficult to wear initially and may take a few weeks to get used to.
Extended and Disposable Lenses
A subgroup of soft contact lenses is extended wear and disposable lenses. According to allaboutvision.com, doctors recommend disposable lenses because they are discarded at the end of the day. This lessens the chance of calcium buildup and health problems associated with long-term contact wear. There is no need to purchase cleaning solution, since they are removed at the end of the day.
An optometrist may give extended wear contacts to people who want long-term wear, including keeping them overnight. Extended wear is convenient for people who don’t like to take the lenses in and out each day. You can simply wake up and go.
