Gradient filters to attach to a frame.
  • All tints are engraved on the lens.
  • As a French optical manufacturer, we can supply tints on request. (Please contact us)
  • The advantage of our filters is that they filter according to a consistent spectrometric chart.
  • Depending on the intended use, choose index 1, 2, 3 or 4.
  • Index 4 is reserved for extreme conditions such as glaciers, or for specific conditions.

The 2 principles in low vision:

1. Short-wavelength (blue) light is scattered the most; eliminating it increases contrast.

  • To do this, blue light is cut from 450 (wavelength) to 585 as cleanly as possible: this is the base tint.
  • This tint can then be varied in light intensity. This gives a whole range of more attractive lenses.
  • Low-vision patients are more sensitive to brightness: the more blue is cut, the lower the light intensity.

2. Reducing brightness creates a diffraction spot, which improves the ametropia.

Note:

  • Blue-violet rays can be harmful to the eye (especially the retina); all low-vision lenses cut them.
  • A good knowledge of filters and careful listening to the patient make it easy to fit them in the best possible way. For indoor use, fit the lightest possible tint, and remove it before going out so that the iris adapts to the strong outdoor light; otherwise the eyewear may become a nightmare outdoors. Indoors, it is best to use low-vision tints of intensity 2 at most, except in extreme cases. Fitting well takes judgement and flexibility, as there are no absolute solutions.
