Hypersensitivity tints
A valuable aid in everyday life
Around 10 to 12% of the population experience persistent difficulties when reading or learning due to hypersensitivity to light and contrast. This often little-known phenomenon can cause visual distortions ranging from confusing letters to cognitive fatigue that limits comprehension.
Common symptoms
Although this condition is not a conventional (refractive) vision disorder, it has a direct impact on everyday life:
-
Reading difficulties: Letters seem to move, vibrate or overlap.
-
Early fatigue: An abnormally high concentration effort to process visual information
-
Physical discomfort: Headaches or glare from fluorescent lighting or glossy white paper.
Principle: Precision colorimetry
Using precision color filters (tinted lenses) changes the perception of the light spectrum reaching the retina. By neutralizing disruptive light frequencies, "visual noise" is reduced.
The result is immediate for the wearer: black text on a white background becomes stable and restful, freeing up cognitive resources for comprehension rather than mere decoding.
Implementation
As with all tints, it is recommended that tests be carried out beforehand so that the patient can determine for themselves which tint suits them best. In most cases, these tests are carried out in conjunction with orthoptists.
