The many varieties of the contact lens
If you’ve been thinking about changing your frames into contacts, or if you’re looking into getting a different kind, it’s important to be aware of your options. Contacts come in a variety of lens types, and each has its own distinct advantages and disadvantages. Here’s a brief list of the most popular kinds to get you started:
• Rigid gas-permeable: This is the basic kind of contact lens. It is made out of slightly flexible plastic and provides wearers with the highest quality of vision possible. It is also generally durable. However, in order for the lens to adapt to a person’s eye, he must wear it very frequently and make sure it is not slipping off-center.
• Daily wear soft lenses: These lenses are made out of soft, flexible plastic. According to the American Optometric Association (AOA), daily wear soft lenses are great for active lifestyles because they are comfortable and do not come out easily. They’re also available as tints and bifocals. However, the lenses do need to be replaced more often, as they get dirty easily.
• Extended wear lenses: This type of lens, as indicated by the name, can be worn for longer periods of time than the typical contact lens – including overnight and for up to seven days. The downside is that eyes are more prone to complications when wearing the same lens for such a long period of time. There is also a disposable version of the extended wear lens, which offers many of the same benefits as the daily wear lenses. The AOA suggests patients wear the disposable version for one to six days before discarding them and starting fresh.
To get more information about any of these types of contact lenses, schedule an appointment with your True Care plan-accepting eye doctor and ask how True Care can make your next pair of contacts even more affordable.
