optical power of a lens. In the case of spectacle lenses, negative dioptre values correct short sightedness, positive values correct long-sightedness. The dioptre is equal to the reciprocal value of the focal [...] long-sightedness, which can be corrected through the use of a vision aid. The visual impairment caused by other sight defects, such as night blindness or amblyopia, cannot be corrected. What is amblyopia? Amblyopia [...] Amblyopia is a vision defect where the visual loss cannot be corrected by wearing even the best corrective glasses. It can be congenital. This also includes, for instance, strabismic amblyopia. When squinting
