Gas permeable contact lenses are very comfortable choice and quite popular with contact lens wearers today. These lenses are more rigid than traditional soft lenses and therefore, have some advantages with vision correction. The oxygen permeable polymers used to make the lenses are better at holding the shape of the lens and this means that the vision correction can be clearer.

Your typical soft contact lenses contain a lot of water but the gas permeable lens is less watery and therefore less susceptible to protein deposits that can accumulate on the lenses blurring your vision. Another advantage of low water content is that the lenses are less likely to harbor bacteria. Both of these things are critical components of good eye health.

With the gas permeable contact lenses, oxygen can still flow through the lens into your cornea but the plastic itself is more durable which makes the lenses less prone to becoming damaged and easier to handle. These lenses are great for extended wear because of the high degree of gas permeability. Allowing oxygen into your eyes is critical because when your eyes can breathe they can flush away bacteria and other pollutants like they are supposed to. In addition, they help keep your eyes from becoming irritated and dry.

These lenses are not flimsy and flip floppy like soft contact lenses and won't dry out or tear as easily provided that you care for them properly. This can save you money because a torn lens is no good and needs to be thrown away.

Although the lenses do have benefits, they are not really as comfortable as the traditional soft lenses. The first couple of days might be particularly uncomfortable and you will spend some time getting used to the lenses. However, once your eyes adjust to the lens they can be quite comfortable. If you don't wear them all the time though, you'll have to go through the same thing each time you wear them for you to get used to them.

Another big drawback of gas permeable contact lens is that when you take them out sometimes you can get blurry spots on them that might take a couple days to clear up. This usually causes people to stop wearing the lenses but then this starts the adaptation period of getting used to them all over again.
