No, it's an area of affect spell, not a ray spell. It doesn't even have a target section.
Every creature in the area takes damage, no attakc roll, but saving throw halfs the damage and negates the blindness. The saving throw is also an indicator there's no attack roll, as spells don't usually have two different was to negate their effects, unless that's warranted by an exceptionally powerful effect, like Phantom Killer.
