What are RGP contact lenses? Who are they suitable for?

RGP contact lenses

RGP contact lenses stand for Rigid Gas Permeable Contact Lenses, which means rigid gas permeable corneal contact lenses in Chinese. They are the smaller members of the contact lens family!

RGP is a high oxygen permeable hard contact lens worn during the day. The polymers such as silicon and fluorine contained in it can greatly increase the amount of oxygen passing through. After wearing the lens, the field of vision is wide, which is basically the same as the field of vision of the naked eye. The prism effect is small, the optical image quality is good, the aberration is reduced, and the vision is real.

It is a good correction method for high myopia, high hyperopia, high astigmatism, keratoconus, postoperative aphakia, refractive errors after corneal refractive surgery and corneal transplantation.

RGP contact lenses are suitable for people

(I) People with refractive errors, especially those with high myopia, high hyperopia, anisometropia, etc., can choose to wear RGP contact lenses to improve aesthetics.

(ii) In cases of keratoconus, corneal perforation injury, corneal transplantation, etc., when there is irregular corneal astigmatism, you can choose to wear RGP contact lenses to improve corrected vision and visual quality.

(III) Children with congenital cataracts. If artificial lenses are not implanted after surgery, it is recommended that they wear RGP contact lenses to promote visual development.

(IV) People who wear soft lenses for a long time. If you have problems such as corneal hypoxia and corneal neovascularization, but do not want to wear frame glasses, you can also wear RGP contact lenses.

RGP contact lenses VS frame glasses

RGP contact lenses

advantage:

1. It is not easy to be noticed and is easily accepted by others.

(2) It has a broad vision and is suitable for people engaged in certain special professions.

(III) Good visual quality and clear vision. It eliminates the prism effect produced by frame glasses and reduces the magnification difference between the two eyes.

4. Correct irregular astigmatism on the corneal surface.

shortcoming:

1. Daily care and cleaning of lenses must be carried out strictly in accordance with the requirements.

(2) Removing glasses is more cumbersome than wearing frame glasses and they need to be replaced regularly.

(3) There will be a foreign body sensation when you first wear it, and it takes some time to get used to it.

Frame glasses

advantage:

1. While correcting vision, the lenses are comfortable to wear and easy to put on and take off.

(ii) It does not come into direct contact with the cornea, does not cause any physical damage to the eyes, and will not cause any corneal complications.

shortcoming:

(1) There are inconveniences in daily life and exercise.

(2) If you fall, it is easy to cause damage to your eyes.

(3) It is impossible to control the increase of myopia, but it can only solve the eye demand.
