## What is DaltoTest?

DaltoTest screens color vision wherever you are, with five methods inspired by ophthalmology: no appointment, no specialized equipment, no account to create.

FIVE METHODS
• Ishihara plates: numbers hidden in colored dots, red-green screening
• Farnsworth D-15: arrange 15 caps in a gradient, blue-yellow coverage
• Extended FM-100 test: 96 caps in 4 rows, more sensitive to mild deficiencies
• Lantern test: identify brief signal lights, professional-qualification style
• Test inspired by the Cambridge Colour Test: spot a ring hidden in a dot mosaic

Wondering about your color vision? It happens: you wonder if you really see red and green the way everyone else does, or if your kid keeps mixing up colors at school. DaltoTest lets you check in a few minutes, wherever you are, no appointment needed.
