Definitions

  • the invention relates to a radiation protection filter for main pigmentation when exposed to the sun.
  • the pigmentation resulting from the action of certain spectral ranges not only gives a pleasantly tanned appearance that corresponds to today's cosmetic tones, but also protects the unprotected skin from harmful. Radiation.
  • the pigment storage in the skin largely protects against erythema radiation, the wavelength of which is shorter than 320 nm.
  • the invention is therefore based on the object of designing a radiation protection filter for skin pigmentation when exposed to the sun in such a way that radiation-induced eye damage is avoided.
  • the radiation protection filter is designed as tanning glasses, it should be designed such that, on the one hand, the area of skin in the vicinity of the eye covered by the glasses is sufficiently browned, but on the other hand radiation-related eye damage is avoided.
  • the radiation entering the lens of the human eye is determined by the irradiance in the pupil plane and by the pupil surface (ie the size of the eye hole in the iris).
  • the pupil area F in turn is regulated in healthy middle-aged people by the illuminance E vis present in the pupil plane . Since it is very difficult to measure the irradiance or illuminance directly in the pupil plane, the corresponding tangential values for the front of the eye (corneal irradiance or homopod illuminance) perpendicular to the visual axis are used for the calculations.
  • the invention is based on the assumption that the risk of lens damage (cataracts) from radiation of 340 to 400 nm when exposed to the sun and unprotected eyes is tolerable for a healthy person. Under this assumption, the invention ensures that when the eye is protected (ie when using a radiation protection filter) no more of this radiation (between 340 and 400 nm) can enter the lens than when the eye is unprotected. On the other hand, the invention ensures that as much radiation as possible in the region between 340 and 440 nm which is effective for skin tanning can strike the area of the skin covered by the radiation protection filter.
  • the basic requirement for the invention is therefore:
  • the irradiance E 31 with the eye protected by a radiation protection filter in the wavelength range between 340 and 400 nm
  • the irradiance E 30 with the unprotected eye and the mean transmission T 3 there is the following relationship:
  • the light transmission Tvi.s can generally be determined from the following relationship: ⁇
  • the pupil area F also has the following relationship with the corneal illuminance E vis :
  • Influencing the average transmission T 1 , as well as the light transmission vis takes place by incorporating organic, UV-absorbing substances and organic soluble dyes or pigments or inorganic pigments into the plastic material of the radiation protection filter.
  • UV-absorbing substances are benzophenones, benzotriazoles, compounds of salicylic, cinnamon and oxalic acid and compounds which are formed from these substances by modification.
  • the impact strength should be ⁇ 30 kJ ⁇ m -2 .
  • the maximum permissible pupil area F 1 of the protected eye thus results from equation (7) at 3.15 mm 2 .
  • This pupil area is therefore smaller than the maximum permissible pupil area of 3.15 mm 2 .
  • PC polycarbonate
  • the requirements regarding the transmission values can be met if the material UVASUN 103 (Mutzhasados-GmbH, Kunststoff) and the dye 205 are used as steep edge absorbers (Mutzhas principles-GmbH, Kunststoff) can be used.
  • the spectral transmission curve desired for the glasses can be calculated by changing the concentrations of UV absorber and dye. From this the values of 4 as well vis .
  • the transmission values are as follows: T 2 0.001
  • T 3 0.41
  • Filter plates for covering sun terraces are to be produced in red-violet color, with an impact strength ⁇ 40 kJ ⁇ m -2 and the following transmission values: 2 ⁇ 0.01 3 ⁇ 0.45 T 4 ⁇ 0.55
  • a filter film for covering umbrellas (awnings, tents, etc.) with the transmission values is desired:
  • Glass or plastic should be coated with a purple filter varnish, which has the following properties for glasses, vehicle sunroofs, glazing, flexible shields, etc.:
  • the validity range of equation (8) ranges from 0.005 lx. (Corresponding to an apparent pupil width, i.e. a pupil diameter visible from the outside of the eye, from 8mm and a size of the eye hole in the retina of 7.14 mm) to 50,000 lx (corresponding to one apparent pupil size of 1.5 mm and a size of the eye hole of 1.34 mm).
  • the values given for the transmission in the description are the values of the directional transmission with perpendicular radiation incidence (which is generally smaller than the scattered transmission).
  • T 1 average transmission of the radiation protection filter from 250 - 300 nm 2 average transmission of the radiation protection filter from 300 - 340 nm
  • T 3 average transmission of the radiation protection filter from 340 - 400 nm 4 average transmission of the radiation protective filter from 340 - 440 nm

Abstract

Un filtre protecteur contre des rayonnements est utilisé pendant le bronzage de la peau par l'exposition aux rayonnements solaires. La transmission de lumière du filtre protecteur dans la plage de longueurs d'ondes comprises entre 380 et 780 nm est calculée pour que pendant l'utilisation du filtre protecteur il pénètre au maximum dans le cristallin de l'oeil autant de rayonnements compris entre 340 et 400 nm que lorsque le filtre protecteur n'est pas utilisé. Des lésions de l'oeil provoquées par les rayonnements sont ainsi évitées.
