Orthokeratology lenses are a type of glasses that are specifically designed for myopia, astigmatism, and corneal irregularities. These specially designed glasses work by applying pressure to the cornea to change the curvature of the cornea, thereby temporarily improving vision. Orthokeratology lenses are usually worn at night and removed during the day to use sleep time to shape the eyeballs. This way is called:"Overnight** eyeglass correction"(Orthokeratology, abbreviated.)"ortho-k")。With orthokeratology lenses, people can see clearly during the day without the need for glasses or glasses.
The functions of orthokeratology lenses include:
1.Temporary vision correction: By shaping the cornea, orthokeratology lenses can provide clear vision during the day, reducing the dependence on glasses or traditional** glasses.
2.Controlling myopia progression: Some studies have shown that orthokeratology lenses can slow the progression of myopia in children and adolescents, making their myopia grow more slowly.
3.Suitable for activities and sports: Since they do not need to be worn during the day, orthokeratology lenses are suitable for people with activity and exercise needs, such as sports enthusiasts and athletes.
Although orthokeratology lenses have many advantages, their use requires evaluation and guidance from a professional optometrist or ophthalmologist. In addition, there are risks associated with the use of orthokeratology lenses, including the possibility of dry eyes, corneal infections or other eye complications. Therefore, before deciding to use orthokeratology lenses, individuals should fully understand the pros and cons and seek professional advice.
