Achromatopsia Glasses
What is NeuroTint™?
NeuroTint is precision-tinted eyewear designed by optometrists to help people who live with light sensitivity. Our lenses are engineered to filter bands of light that commonly trigger discomfort in migraine, concussion recovery, visual snow, ocular surface pain and related conditions. The goal is simple. Less light-triggered pain. More comfortable days!
How NeuroTint Lenses Help with Achromatopsia
Achromatopsia is a rare, inherited vision disorder characterized by a complete or partial inability to perceive colour. Individuals with achromatopsia typically experience extreme light sensitivity (photophobia), reduced visual acuity, and difficulty seeing in bright conditions. This condition is caused by mutations in genes responsible for cone cell function in the retina, leading to a reliance on rod cells, which are highly sensitive to light but do not detect colour.
One of the most effective ways to manage the symptoms of achromatopsia is through the use of specialised tinted lenses. These lenses help by filtering specific wavelengths of light, reducing glare, enhancing contrast, and improving visual comfort.
Key Benefits
- Reduction of Photophobia: By limiting the amount of bright light entering the eyes, tinted lenses help minimise discomfort caused by excessive light sensitivity.
- Improved Contrast Perception: Filtering certain wavelengths enhances the ability to distinguish objects in different lighting conditions.
- Enhanced Visual Acuity: By optimizing the remaining functional vision, tinted lenses can improve overall clarity and detail perception.
Specific Wavelengths and Filtered Light
The most beneficial tinted lenses for achromatopsia typically filter out high-energy visible (HEV) light in the blue and green spectrum. Research suggests that blocking wavelengths in the range of 480-650 nm can significantly improve visual function for individuals with achromatopsia.
- C01 PLUM: These lenses block nearly all blue and green light, significantly reducing photophobia and enhancing contrast.
- NOIR 81 (Dark Grey/Plum): These reduce overall brightness without distorting colour perception further, making them useful in certain indoor environments.
Scientific Research and References
Studies have demonstrated the effectiveness of tinted lenses for managing achromatopsia:
- Park et al. (2015) found that red-tinted lenses significantly improved comfort and reduced photophobia in patients with congenital achromatopsia.
- Sharpe et al. (2005) discussed how selective wavelength blocking enhances visual performance in low-functioning cone conditions.
- Zrenner (2002) highlighted the benefits of customised optical filters for improving contrast sensitivity and visual clarity.
