Maybe although he sat in this type of water his whole life (7+ years). The water is also filtered at the main line in the house, it doesn't remove 100% of the chlorine but removes most of it.
That being said it hasn't gotten worse, when he's in the water it's impossible to notice it. It just looks normal like the other eye, it only is visible when there's a strong light above it. Maybe that's a deformity he has and I just never noticed, I'll keep monitoring him.
