Reducing Blue Light (Shorter Wavelengths)
| Everyday light is composed of a spectrum of colors from blue to red. Blue light is a higher energy light which tends to scatter more off small particles in the atmosphere or in the fluids of the eye than other colors. | ||
 |
In the sky, blue light scatter creates the blue sky we all enjoy. In the eye, it can cause a hazy blur which disrupts our vision. | |
| Amber filters reduce the blue light component of white light and may enhance the sharpness of what we see by lessening the scattering of light. | ||
 |
The example here shows the over-exposed glare that a low vision patient may experience. Note that with an amber filter shown on the right side, the exposure is better and the detail is improved | |
| Patients who frequently benefit from moderate blue light
reduction such as amber filters include:
Macular Degeneration Patients
|
||
| The darkest form of blue reduction filters are the plum shades.
Conditions which may be aided with these darker filters may include patients with:
Achromatopsia
