What you see is a small reflex of led light bulb on the lens. One simple and quick way to find out is to use your cellphone to take a photo of the dot.If you see a circle dot in the photo you took, you basically diagnosed you have Astigmatism(Because cellphone is a machine does not has human astigmatism)
