increase in seeing increased color variations
My son is 7 1/2 and has a strong Protan red/green colorblindness just like his grandfather. His grandfather has these sunglasses in adult version and loves using them for driving as he can see the sky as much bluer and can finally see the red and stop lights for the first time in his life (rather than just knowing when to stop or go based on which light is lit up.) My son has a narrow face so the age 5-10 glasses are still a bit loose on him, and he's not used to wearing sun glasses, but I think he will wear these more over time. He hasn't noticed too much difference in colors, but can tell more variations in purple and blue, and dark greens verse browns. They definitely work best in bright sunshine outside, great for biking, hiking, trips to the park.
