There are three main different types of contact lenses; the original hard PMMA contact lens, the soft contact lenses and gas permeable contact lenses. Soft contacts are much more well-known and common but gas permeable contact lenses (GP) are preferred by many people due to their many benefits.
Gas permeable contact lenses are made of a plastic material which is robust and firm, which also allows oxygen to permeate through them. They offer optimal eye health by letting your eyes breathe. For these reasons GP’s are also often referred to as oxygen permeable contact lenses and rigid gas permeable lenses (RGP).
Soft lenses are immediately comfortable. The only disadvantage of GP’s is that they are less comfortable than soft lenses at first. However, most people adapt to them quickly. If you stop wearing them for about a week or so your eyes will have to re-adjust to them.
GP contact lenses contain silicone, which in itself does not contain water, therefore protein, lipids and other mineral deposits from your tear ducts will not develop on the lenses. This also means they do not dry out over time, so there is less of chance of eye irritation and itchiness.
GPs are particularly durable. Although they are breakable, they do not tear as easily as soft lenses. They are easy to clean and disinfect and because they are so robust they go a very long way compared to soft lenses meaning you need to replace them less frequently. Add to this the fact that they are cheaper and you will be spending a lot less money in the long-run.
GP contacts have superior optics. Since they’re firm, your eyes don’t have to refocus as much after you blink. They are also ideal for astigmatism or bifocal complaints. GP contact lenses come in many designs that address bifocal, and multifocal needs. An optician can easily establish the correction your eyes require, so his or her advice on the shape, size, shape, and other features is very important.
Advanced techniques can be utilized to make the gas permeable contact lenses optimally fit on the cornea. Amendments can be made to match the topography of the eyes and GP lenses are constantly being upgraded to thinner, wider and with smoother edges.
The speed at which your eyes adjust to their new lenses is to only real disadvantage of gas permeable contact lenses. In the long-run, the custom-built lenses will only mean positive things for your eyes. They will ensure you of clearer vision, maximum comfort (after the “getting to know you” period), cheaper, more robust and cleaner lenses.
