Keeping this in mind, Is it bad to wear Ortho-K lenses during the day? Can you wear ortho-k lenses during the day? Yes.

Method of optical correction by Excimer laser photoablation, which changes the shape of the cornea to change the refraction error. The treatments are symmetrical and correct lower order or spherocylindrical aberrations, which include myopia, hyperopia, and astigmatism.

Is ortho-k better than LASIK?
For 6-mm pupil size, LASIK provided significantly better VA values than ortho-k at 50% and 10% contrast levels for low myopia correction (P = 0.002 and P = 0.001, respectively) and at all contrast levels for moderate myopia correction (P = 0.04 at 100%, P < 0.0001 for 50% and 10% contrast levels).
How much does ortho-k cost?
Ortho-k prices in the U.S. generally range from $1,000 to $2,000 (for both eyes), making the procedure about half the cost of LASIK. But particularly difficult cases of ortho-k can cost as much as $4,000.
