There are several things to consider if you wear glasses and are considering trying contact lenses. Certainly, you are aware of some of the benefits of wearing contacts, such as freedom from heavy glasses as well as better peripheral vision. You may be a little nervous about wearing contact lenses or even care and maintenance. Before thinking about these details, you should know a little bit about the different types of contact lens options that are available to you. Familiarizing yourself with the various lenses currently on the market will take you one step further. Below is an overview of some of the different lenses your ophthalmologist can recommend for you. Equip yourself with the following information before going to your eye doctor and you will be in a better position to know what is best for you.
Torque lens
Torque lenses are designed to have the effect of a cylindrical lens, usually combined with the effect of a spherical lens. Torque lenses are commonly used by insightful and far-sighted people who also have a bad temper. Generally, these people are told that they are not suitable for regular contact lenses, but they may be able to use torque lenses. If you have astigmatism in one eye and not in the other, you may be asked to use a spherical lens in one eye and a torque lens in the other. Torque lenses are made from the same material as ordinary contact lenses, but there are some notable differences. Some of these differences include:
– They are not symmetrical and may contain a specific ‘up’ and ‘down’
– They should be designed to maintain their familiarity.
– They are correct for both cylindrical error and spherical error.
– They can be a bit more expensive and are usually for long dresses.
Hard gas permeable lens
Hard gas permeable contact lenses were introduced in the late 1970s. Although hard gas permeable lenses (or RGPs) are harder or stronger than soft contact lenses, they should not be confused with the old style of ‘hard’ contact lenses, which are no longer used. Most hard gas permeable lenses contain silicone, which is oxygen permeable. Basically, this means that oxygen can physically reach your eyes through the lens. Hard gas permeable lenses usually last longer than soft contact lenses. They can also provide better vision, stability, and accumulation resistance. RGPs can be easy to clean and can be cheap in the long run due to their long-lasting quality.
Glass lens
Glass contact lenses are primarily hard gas permeable lenses designed to be worn for up to a year. Glass lenses must be removed, cleaned and disinfected at night. Glass lenses can be either soft or hard. The main difference between glass lenses and other types of contact lenses lies in the amount of time a pair of lenses will last. Although the popularity of everyday wear contact lenses and disposable lenses has increased, people still prefer the durability of hard gas permeable glass lenses. Glass lenses last a long time and are said to provide excellent vision correction. On the other hand, they are thicker than disposable lenses and may take some time to get used to.
The choice is yours
Now that you know a little more about some of the different types of contact lenses available, you’ll be better equipped to make your own vision care decisions. Be sure to consult your doctor about specific lifestyle and vision issues to help you further determine which lenses are best for you.
When searching for contact lenses online, be sure to do your research and look for a contact lens provider that offers all the most popular types of contact lenses, including torque lenses, RGP lenses, and wile lenses.
I recommend that you shop for contact lenses at designer optics. Designer Optics is the best online platform for contact lenses.
