Can ok lenses be used after 18 years old

They can be used after 18 years old.

Strictly speaking, there is a lower limit but not an upper limit to the age requirement for wearing orthokeratology lenses. Therefore, people over the age of 18 can also wear keratoconus lenses. After the age of 18, the eyes are fully developed and the refractive error tends to be stabilized, then myopia can be corrected by myopia surgery and the lens can be removed in the real sense. Therefore, many people will choose to have their myopia corrected by means of myopia surgery after reaching the age of 18, instead of choosing to continue to wear corneal reshaping lenses. The State Drug Administration also specifically proposed that keratoplasty lenses belong to the class of medical devices, only qualified ophthalmic institutions are qualified to carry out testing and dispensing.

Therefore, when parents are fitting their children with keratoplasty lenses, they must choose a regular ophthalmology organization to do the fitting and use them under the guidance of an ophthalmologist, and go to the hospital on a regular basis to receive a review and maintenance by an optometrist, which is safer for nearsighted children and adolescents.

Generally speaking, the regular eye institutions have a scientific fitting, use of the program, check the equipment is more complete, and there are specialized optometrists regularly for children with glasses to carry out ophthalmological examinations, lens care, vision testing and other tasks.

Theoretically, people who are 8-40 years old, with 50-600 degrees of true myopia, normal corneal curvature, normal intraocular pressure, no ocular diseases, no ocular inflammation, and no incomplete eyelid closure are suitable for wearing OK lenses. Therefore, it is necessary to go to the regular eye hospital after a complete medical optometry examination to finally decide whether it is suitable for wearing.

Because teenagers' eyes are not yet fully developed, they are not suitable for myopia correction surgery, so the current wearers of OK lenses are mainly teenagers.
