There are many types of contact lenses. The variety in these types of contact lens comes in their various styles, standout points as well as drawbacks. Choosing a specific contact lens in the face of such diversity can be overwhelming. Let us therefore examine some of the most common types of contact lenses that pervade the market today, and the pros and cons of each category as well.
Rigid, gas-permeable lenses
The first we will be addressing are the rigid gas-permeable lenses. Basically, this type of contact lens is designed with a flexible plastic. It is such that it allows for passage of oxygen to the eyes. One lovely thing about these contact lenses is that they provide a very crisp vision.
A larger percentage of people who use the rigid gas-permeable lenses don’t feel significant discomfort wearing in wearing them. Moreover, this contact lens is very effective in correcting the defects in your vision. They have an impressive lifespan so long as you adequately take care of them. For those with a knack for fashion, the rigid gas-permeable lenses present a diversity of tints so you can choose which matches your taste.
However, in the beauty of these rigid gas-permeable lenses are some downsides as well. While they are commendably comfortable, they are not as comfortable as soft contact lenses. Often, these lenses have the tendency of slipping off the center of your eyes more than you would experience with other lenses. Another is their susceptibility to the penetration of debris which could get beneath them, causing measurable irritation to your eyes.
Daily-wear soft lenses
This is another common choice of contact lenses. They are designed with flexible plastic and are significantly softer, which allows for easier passage of oxygen to your eyes. Compared to the aforementioned rigid gas-permeable lenses, they feel more comfortable and would not easily slip on your eyes. These daily-wear soft lenses are easily acquirable in various bifocals as well as tints. For people with a more active lifestyle, the daily-wear soft lenses would make a better choice among contact lenses.
On the downside, daily-wear soft lenses do not provide the same level of crisp vision. When measured against aforementioned rigid gas-permeable lenses, the vision doesn’t boast the same level of sharpness. Moreover, the daily-wear soft lenses are more vulnerable to wear.
A huge number of people are jumping to extended-wear contact lenses. These lenses allow you to sleep with them while still on your eyes. Admittedly, extended-wear contact lenses feel really soft on the eyes. In other cases, they could be rigid gas-permeable.
Nevertheless the downside to these lenses, just like the daily-wear soft lenses, are that they are also selective in the vision defects they correct. Another thing is that these lenses get you more prone to eye infections.
In the end, it is always advisable to consult your eye doctor for the perfect choice of contact lens.
