Color vision deficiency (CVD) affects roughly 8% of men and 0.5% of women of Northern European descent. Contrary to common myths, most people with color blindness do not see the world in black and white; rather, their eyes perceive colors within an overlapping or reduced gamut.
Types of Color Vision Deficiency
- Deuteranomaly (M-cone shift): The most common form (approx. 5% of males), where green cone photoreceptors have an altered spectral sensitivity shifted toward red.
- Deuteranopia (Missing M-cone): Total absence of green-sensitive cone photopigments.
- Protanomaly (L-cone shift): Red cone photoreceptors have a shifted spectral peak toward green.
- Protanopia (Missing L-cone): Total absence of red-sensitive cone photopigments, often resulting in red colors appearing substantially darkened.
Why Screen Polarization Works for All Subtypes
Because VIOSENSE eyewear uses polarized light modulation to produce differential signals rather than relying on the activation of a missing cone type, it provides functional assistance to both anomalous trichromats and dichromats across digital displays.
