Many people with vision problems prefer using contact lenses to eyeglasses. Besides correcting eye conditions, contacts are therapeutic and comfortable eyewear, and in a number of ways, they are definitely superior to eyeglasses. There are several types of contact lenses, but in general they are categorized into two, the soft contact lenses and gas permeable contact lenses. Although soft contacts are more common to many users, a lot of people prefer gas permeable (GP) contact lenses owing to a variety of advantages.
Gas permeable contact lenses are also known as rigid gas permeable (RGP) lenses or oxygen permeable lenses. GPs are called rigid because they are made of firm materials that transmit oxygen. They are smaller and more durable compared to soft contact lenses. The eyes require that sufficient oxygen pass through them, and GP contacts provide that breathability that the soft type cannot match. The firm materials that make up GP contacts do not contain water, thus protein and mineral deposits are not going to build on the lenses. They do not dry out either, so the eyes are less likely to get itchy. Because of these factors and more, gas permeable contacts provide better vision and are the excellent choice for people with various eye conditions.
Whether you are getting rid of your eyeglasses or soft contact lenses, consider the following factors in selecting gas permeable contact lenses.
- Consult an eye care professional prior to searching for GP contacts. A prescription is essential in buying your contact lenses. You need to have your eye condition checked in order to be given the accurate solution for your vision problem.

It is your eyes you are taking care of, so it is important to understand the disadvantages and possible effects if you use this type of lens. While GP lenses provide optimal vision correction for a variety of conditions, are more durable and better for eye health, etc., you need to know that they are initially uncomfortable to wear. They need an adjustment period, and you will have to readapt should you stop wearing them for a while. Get as much information as possible to be aware and prepared when you use them.
- GP contacts have a variety of designs that cater to monovision, bifocal, and multifocal requirements. Since your eye doctor can very well determine the correction your eyes need, choose the GP lenses according to your eye practitioner’s advice on the shape, size, tear film, and other features.
