Definitions

  • the utility model relates to medicine and, in particular, to ophthalmology, and provides a comprehensive optical and spectral reduction in visual loads and protection of the visual apparatus when working at close range. It is applicable as a means of comfort, primary prevention, treatment and secondary prevention of visual disturbances.
  • phototoxicity damage to the retina and pigment epithelium of the eye is understood to be certain parts of the spectrum.
  • the ultraviolet-blue part of the spectrum has the most pronounced damaging effect on the eye, with toxicity rapidly increasing with decreasing wavelength (from 400 nm or less), blue-green phototoxicity reaches a peak near 500 nm and rapidly decreases at higher and lower wavelengths.
  • Blue-green phototoxicity has a spectrum of action similar to that of sensitive vision.
  • the main natural filter protecting the retina is the lens.
  • the cornea and shielding pigments also play a role in protection from photo damage [1, 3].
  • Short-wave light (blue-violet) is most susceptible to refraction and scattering both in the atmosphere and on the boundary surfaces of the eye media, therefore falls on the retina at the focal point of long-wave rays (red) [1]. As a result, a “blurred” image is imprinted on the retina.
  • Utekhin's bifocal sphere-prismatic glasses proposed by the author for the treatment of myopia [2].
  • the same approach is embedded in glasses for the prevention and treatment of visual fatigue syndrome Lalina et al. [2], as well as in Yermoshin's monofocal sphere-prismatic glasses (sphere-prismatic simulator glasses) used for the primary prevention of vision disorders caused by work at close range [3, 4].
  • Spherically prismatic glasses provide optical unloading of the lens muscles and muscles that bring the axis of vision to one nearby point, due to the transfer of lenses part of the work of accommodation and convergence.
  • Useful effects are achieved due to the plus lenses of small strength (“remote lens”), unloading the lens of the eye) (up to 1, 5 - 2.0 diopters) and prisms located in the frame with the base to the nose (up to 4-6.5 prismatic diopters) which provides the expansion of the field of view, the release of the eyes from convergent loads.
  • relay lens small strength
  • prisms located in the frame with the base to the nose up to 4-6.5 prismatic diopters
  • the purpose of creating a utility model is the comprehensive protection of the visual apparatus from the harm caused to it by prolonged muscle loads when working close to it, the suppression of chromatic aberration that impedes the clear projection of the image on the retina, as well as the filtering of the ultraviolet-blue and blue-green parts of the spectrum, of natural origin and emitted by technical devices having a damaging effect on eye structures.
  • Unloading of the ciliary muscles is achieved due to the spherical component in the eyeglass lenses, selected according to the principle of comfort (the search is carried out in the area of 1, 5-2-2.5 (maximum up to 3.0) units in the plus side of the eye refraction value determined in the usual way) ; the prismatic component of spectacle lenses (prisms with the base to the nose, up to a maximum of 6.25 prdptr) provides comfortable work of the internal rectus muscles of the eye; spectral protection of vision from phototoxic parts of the spectrum and an increase in contrast perception is achieved by filters that cut off the ultraviolet-blue and blue-green parts of the spectrum.
  • the hybrid model provides:
  • sphere-prismatic spectacle lenses produced by any of the known technologies (polishing from semi-finished products by the principle of prescription lenses, casting from thermosetting plastics, etc.) are equipped with a light filter that delays parts of the spectrum that impede contrast perception and are dangerous in terms of damage to structures eyes.

Abstract

La présente invention concerne la médecine, plus précisément l'ophtalmologie, et assure une réduction combinée de la fatigue oculaire lors du travail à faible distance grâce à la combinaison de deux effets optiques dans un dispositif unique, à savoir l'allégement de sphéro-prismatique de efforts musculaires accommodant et convergent, survenant lors du travail à faible distance, et l'allégement spectral du système visuel par une réduction de l'aberration chromatique et de la « photo-toxicité » au moyen de filtres de lumière qui bloquent les composantes violet-bleu et bleu-vert du spectre dans les gammes de 400 nm et moins et 500 de nm, respectivement.
