It was the 60s when jessen, an american optometrist, first used the concept of orthokeratology or ortho k lenses . From then until today, this method of advanced contactology to correct vision has experienced great advances thanks to technology, but what are they? What are the most innovative applications currently? This alternative to traditional treatments began as a scheduled sequential placement of neutral pmma (polymethyl methacrylate) contact lenses flatter than the patient's corneal curvature. In this way, it was possible to alter his corneal curvature and temporarily correct his myopia. The only drawback was that this type of lenses were very unstable and frequently produced irregular astigmatisms that prevented good vision.

As extracted from the study optical changes and visual performance with orthokeratology, “modern nocturnal orthokeratology causes rapid, reliable and reversible reductions in refractive error.
With modern designs patients can wear these lenses at night, take them off in the morning, and see clearly during the day without needing any type of correction.” ortho k and sport refractive errors are no longer an inconvenience for sports lovers, especially if they involve contact sports. In most disciplines, excellent hand-eye and hand-eye coordination is necessary, but specifically in contact activities, having good vision without glasses or contact lenses is usually one of the essential requirements. In fact, according to the regulations for obtaining national licenses of the spanish boxing federation, a license will not be granted to anyone who has myopia greater than 4 diopters and the lowest value of visual acuity required is 5/10 for a eye and 1/10 for the other. Good visual acuity provides greater safety and precision in movements, better perception of details and, therefore, a reduced risk of injury.
