RGP lenses, the abbreviation of rigid gas permeable contact lenses, has come back. RGP lenses, with their comforts and vision improvement, gain popularities over the past decade, but now they are mistaken for bad name. Whereas, the fact is that RGP lenses, with some improvements, have many more merits than you expect. They even have some features that soft contact lenses can not provide.

At first, comparing to soft contact lenses which are commonly used today, RGP lenses are more durable and resistant to protein buildup, which would be easy to lead to fuzziness. That is to say this kind of lenses can provide a clearer and crisper vision. In addition, for their durability, RGP lenses are not so easy to get fragile which prolong their service time. It is also because of their durability that letters 'L' and 'R' can be marked on the lenses which eliminates confusion. Second, rigid gas permeable contact lenses are good for eyes by providing the wearer with circulating oxygen, making eyes breath. Do not make little of this feature, oxygen volume provided to eyes is of great importance, which can not only protect eyes from getting worse, but also, in some degree, increase eye health.

However, every coin has two sides, there should also be negative aspects concerning RGP lenses. As for their particularity, more time is often needed for one to get accustomed to wearing them, on the contrary, soft contact lenses just ask for several days, whereas acclimation is a necessary process for anyone to try new things. If you never try wearing RGP lenses, you will never know how many merits they will bring to you.

At last, as for the prices, rigid gas permeable contact lenses price higher than soft contact lenses, but for the service time, they are generally cheaper in the long run, because you do not have to change often.
