By the way, is it better to buy ordinary transparent film or color film?

Generally, transparent lenses are thin. If the workmanship is good, there is little difference in comfort between the two. However, color movies can beautify the pupils. Small eyes or godless friends can refer to it. I use the sunshade of Mu Sen constellation. The lenses are quite thin and comfortable, and they also contain hyaluronic acid, which makes me feel nothing all day.
