Why Will, Your Optometrist, Suggest Rigid Gas Permeable Lenses?

Soft lenses can be replaced with rigid gas permeable (RGP) lenses. RGP lenses are constructed of a hard, oxygen-permeable substance. They have several advantages over traditional soft contact lenses. “soft” may be the natural choice for something that will come into touch with your eye, but this is not always the case. If your optometrist has prescribed RGP lenses, it is most likely for one (or more) of the reasons listed below.

1) RGP lenses are permeable.

RGP lenses are oxygen-permeable, allowing air to pass through and your eyes to “breathe.” Because the materials used to make these lenses enable more oxygen to get through, they provide a better oxygen supply. Furthermore, because they are smaller than soft lenses and cover less of the eye’s surface, they allow moisture and oxygen to pass beneath the lens.

2) RGP lenses are customised

This contact lens is tailored to the curvature of your cornea, providing a broader range of vision correction and a more comfortable overall fit. If you can’t wear normal contact lenses because your cornea, for example, is unusually shaped, custom-made RGP lenses may be the solution. These customised lenses are made precisely for your eyes, ensuring a perfect fit.

3) RGP lenses provide better visual quality.

RGP lenses can give sharper vision correction for various reasons than soft lenses. Unlike soft lenses, they will not dry out and change shape. Gas-permeable lenses have a flat surface and retain their shape on the eye. They also move on the eye with each blink, allowing tears to circulate beneath the surface. Soft contact lenses, on the other hand, adhere to the shape of the cornea, move very little, and can dry.

4) RGP lenses are resistant to deposit buildup.

Deposit building is less of an issue with RGP lenses because they have a flat surface and do not absorb or hold water. This also implies that they are less likely to attract and propagate bacteria that might cause eye infections. They’re also simple to maintain and cleanse. All of these advantages contribute to RGP lenses being cleaner, healthier, and safer, not to mention lasting longer than other forms of contact lenses.

5) RGP lenses may reduce myopia progression.

RGP lenses with reverse geometry corneal reshaping appear to assist in correcting your vision today and decrease myopia progression over time. This is especially crucial for children who rely so heavily on their vision for learning and whose myopia may still be slowed or stopped. In addition, these RGPs are used in orthokeratology, which is a procedure that involves the patient wearing lenses overnight to correct vision by reshaping the cornea.

6) RGP lenses are good for astigmatism.

If you’ve been informed that you can’t wear soft contact lenses because your astigmatism is too high, there’s some good news: RGP lenses might be a decent option. RGP lenses have a much wider range of parameters than most soft lenses on the market. Many people with severe astigmatism are relieved to discover RGP lenses and learn that they may wear them comfortably for all-day clear vision.

7) RGP lenses are inexpensive.

RGP lenses, in addition to their other benefits, can save you money in the long term. This is because these lenses may last longer than conventional lenses, lowering the frequency with which you must purchase replacements. In addition, because RGP lenses are stiff, you don’t have to worry about them tearing; they’re also easier to maintain clean for a longer period. As a result, one pair of RGP lenses can last a year or more with good maintenance
