Are RGP rigid contact lenses harmful?

Are RGP rigid contact lenses harmful? RGP contact lenses are also called rigid oxygen permeable contact lenses, its role in juvenile true myopia is effectively controlled, RGP hard contact lenses need to be worn under the guidance of professional doctors, some people are worried about the impact of RGP contact lenses on children's glasses, and hope to seek expert advice, the following can be introduced to you: RGP hard contact lenses RGP contact lenses are the latest generation of contact lenses, RGP rigid glasses contain silicon, fluorine and other polymers, which can greatly increase the amount of oxygen through. Compared with soft contact lenses, it not only improves oxygen permeability, but also ensures the firmness of the material, and has good wetting and anti-precipitation. The control and correction treatment effects of RGP contact lenses on juvenile true myopia and keratoconus have been clinically verified by ophthalmology experts at home and abroad for many years and have been affirmed. In recent years, rigid contact lenses have been rapidly popularized worldwide due to the synthesis and application of polymer materials with high Dk value, high elastic modulus, hydrophilic, anti-precipitation and good biocompatibility. From the above, it can be seen that the high oxygen permeability of RGP contact lens and reasonable lens design can maintain the normal physiological function of the cornea! Advantages of RGP hard contact lenses: 1. The service life of RGP is far greater than that of soft lenses. With proper care, lenses can last up to 2-3 years. Long-term use of lenses is inexpensive. 2. RGP imaging effect is better. 3. RGP can slow down the progression of myopia. 4. RGP can correct large corneal astigmatism and keratoconus. 5. RGP has high oxygen permeability, which is not easy to cause hypoxia and dry eye syndrome, and will not cause changes in the number of corneal endothelial cells. Patients with long-term hypoxia, bloodshot eyes, neovascularization, dry eye, and poor vision correction due to wearing soft contact lenses can be replaced with RGP lenses after their eyes are restored. 6. RGP does not affect the normal exchange of tears, so it has little impact on corneal physiology. Good physiological compatibility makes long-term wearing of RGP lenses less likely to cause corneal hypertrophy and edema. Disadvantages: First-time wearers will have initial symptoms such as foreign body sensation, congestion, tearing, and vision fluctuations after wearing glasses, and the symptoms will gradually disappear with the prolongation of time. Possible adverse reactions include corneal epithelial staining, corneal edema, conjunctival hyperemia, etc., which need to be treated promptly. RGP rigid contact lenses, like contact lenses, require hard contact lens care solution, because contact lenses are worn directly on the cornea, if the lenses are not properly cared for or hands are not cleaned, wearing contact lenses is more likely to cause corneal inflammation and other diseases.
