- Allow viewing in binocular vision.
- Help assess the benefit of polarisation.
The 2 principles in low vision:
1. Short-wavelength light (blue) is the most scattered; eliminating it increases contrast.
- To do this, blue is cut from 450 to 585 (wavelength) as cleanly as possible: this is the base tint.
- This tint can then be varied in light intensity, giving 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. Lowering the brightness creates a diffraction spot, which improves ametropia.
