What is Achromatopsia?
Achromatopsia is a rare condition where a person has no functioning cone cells in their eyes. This results in complete color blindness - seeing the world only in shades of gray. It's often accompanied by severe light sensitivity (photophobia) and reduced visual acuity.
Associated Challenges
- Complete absence of color perception
- Severe light sensitivity (photophobia)
- Reduced visual acuity (often 20/200 or worse)
- Nystagmus (involuntary eye movement)
- Day blindness - better vision in dim light
How VisionFu Helps
Since color filters can't restore color perception for achromatopsia, VisionFu provides alternative tools that enhance the screen experience:

- Text Enhancement: Easier reading with improved clarity
Visual Comfort
- Focus Mode: Dim surrounding content to reduce glare
- Reading Ruler: Line tracking without color dependency
- Custom Color Temperature: Warmer or cooler screen tone
Achromatopsia Statistics
- Affects approximately 1 in 30,000 people
- Autosomal recessive inheritance
- Higher prevalence in certain isolated populations
- No cure exists, but management strategies help
