Night lenses are designed to temporarily reduce short-sightedness until -6.0 diopters as well as astigmatism until -1.0 diopters, by temporarily changing the cornea of the eye. The cornea has a decisive impact on the refraction of light and thus also on vision.

Ortho-k lenses and the cornea are only separated by a thin tear film. Hydrostatic forces exert gentle pressure on the cornea and a slight tensile force on the periphery. This procedure allows to change the shape of the cornea and temporarily correct myopia.

Those special hard contact lenses are usually worn every night. In some cases, every second night can be sufficient. The use of ortho-k lenses is recommended in cases of:

• Short sightedness until -6.0 diopters or astigmatism until -1.0 diopters
• Tolerance problems with other contact lenses
• Desire to do without other visual aids
• Nearsighted and age vision (presbyopic)

Night lenses are highly oxygen permeable. In addition to the positive effects on short-sightedness, night lenses from the company Falco Kontaktlinse are ideal for anyone who feels restricted by their visual aid doing sports or working. Further advantages: no dry eyes while working on a computer, no dust particles between the lens and the cornea, no issues related to hay fever. Presbyopia in cases of short-sightedness can as a well be corrected with night lenses.

Due to the special structure of night lenses, irritations on the cornea that can provoke myopia no longer occur. In the long term, ortho-k lenses also reduce the risk of retinal diseases. With the company Falco Kontaktlinsen we have found the ideal partner to fit such special lenses almost without limits.
