Small hole glasses are characterized by their smaller sized holes. They are of high quality and German or Spanish manufacture. These glasses are indicated for symptoms of high graduation or enough diopters (More than 5.5).
They are NOT suitable for driving vehicles or risk sports.
People with vision problems of more than 5.5 diopters require small holes to see more clearly, which allows a vision comparable to that of normal glasses. They are suitable for high vision symptoms for which prescription glasses are usually prescribed: myopia, hyperopia, astigmatism and presbyopia (strained eyes).
The samll holes of these glasses, both in their hexagonal, conical and pyramidal versions, are smaller in the part closest to the eye and wider in the outer part. Like the larger holes, these types of holes reduce the phenomenon of diffraction halos present in round or cylindrical holes. This phenomenon is especially annoying when looking at screens and monitors such as those of computers, televisions, tablets and phones.
