FACETED GLASSES AND THEIR OPTIONS Russian patent published in 2023 - IPC G02C7/16 

FIELD: household appliances; medicine; medical equipment; ophthalmology; sports.

SUBSTANCE: invention relates to household appliances for satisfaction of human vital needs, medicine and medical equipment, namely to ophthalmology, as well as to sports; it can be used for improvement of vision, correction of visual perception disorders, acceleration of recovery in a rehabilitation period, prevention of visual diseases, as well as for removal of fatigue during and after visual work. The claimed faceted glasses contain diaphragms with optical channels. In this case, diaphragms have a thickness from 0.01 mm to 1 mm, and optical channels have a cross-sectional area from 1 nm² to 1 mm² with a location density of optical channels from 1 channel per 4 nm² to 1 channel per 4 mm², and a value of intervals between neighboring optical channels is from a value equal to a cross-section of an optical channel to values not exceeding ten cross-sections of optical channels.

EFFECT: increase in the quality of an image and a depth of field due to maximum reduction in an area, number, and location density of holes as much as strength of diaphragm material can allow, with its minimum thickness, increase in clarity of transmission of static and dynamic images during movement of a user and/or objects observed by him/her, increase in ergonomics, possibility of individual setting, and expansion of functional capabilities of a product.
