Orthokeratology lenses are used for myopia control.

The effect of the orthokeratology lens in controlling the increase of myopia in teenagers has been unanimously affirmed by the ophthalmology industry at home and abroad. In February 2006, an authoritative ophthalmological journal published a review of the retarding effect of rigidity breathable orthokeratology lens on the progression of myopia in children. This paper reviews the literature on orthokeratology and myopia in the past 30 years and points out that rigidity breathable orthokeratology can prevent or alleviate the progress of myopia, the mechanism of which is that rigid breathable contact lens can inhibit the progress of myopia by providing clearer retinal image quality. Medium and high concentration of atropine will affect students' near-use vision, while low concentration of atropine has not been used clinically in China, so orthokeratology lens has become one of the known myopia control methods with the best statistical effect. In three to five-year case studies, orthokeratology lenses alleviate a 40 to 60 percent increase in myopia compared with wearing a frame lens or a soft contact lens. Other studies have found that 65 to 70 percent of orthokeratology lens wearers show little or no axial length increase.

Metal and other materials are heavy, easy to rust, easy to deform, easy to lead to children's facial allergies, and oppression of the bridge of the nose and temple.

Therefore, summarizing the above factors, the resin frame is the most suitable for children to wear. A high degree of myopia must choose a small frame. If the child's myopia or farsightedness is high, the lens will be very thick, so be sure to choose a small frame. Because the frame type is small, coupled with the lightweight of the resin frame, it has better fixing performance than other materials.
