Another way to check the roundness of the dot is to turn it (sideways) while looking through it, if it’s an imperfect dot it will rotate, eg flare at top goes around, if the dot/sparkle keeps the shape oriented eg flare stays in same place while you turn it’s how your eye perceives the dot (not the dot itself)
