The hexagonal pinhole glasses have holes in the shape of a conical hexagonal pyramid. The hexagonal holes end in a circular shape and are aligned equidistantly. They are NOT suitable for driving vehicles or for risky sports.
Suitable for all symptoms and for all prescriptions up to 14 diopters. They combine all the advantages of conical and pyramidal holes.
The hexagonal holes are smaller near the eye and more open on the outside. This type of holes also reduces the phenomenon of diffraction halos present in round or cylindrical holes. This phenomenon is especially annoying when looking at screens and monitors such as computers, televisions, tablets and phones.
In this model the size of the holes is smaller than the conical ones but larger than the fine ones, being valid due to its characteristics in all cases. Specifically, they serve for all symptoms with any graduation up to 14 diopters.
They are suitable for all vision symptoms for which prescription glasses are usually prescribed: myopia, hyperopia, astigmatism and presbyopia (eyestrain). And for all its graduations, whether low, medium or high, that is, for any number of diopters up to 14.
