What is the right side?

A question that most new users have: “How can I tell if my contact lenses are inside and out?”

The difference may be small, but before inserting a contact lens on your eye, make sure it looks like half a ball, it doesn’t look like a dish. The lips of the lens should not protrude. If you wear a contact lens with a light tint (blue, green), then its edges should look especially colored. If the lens is upside down, then there will be no difference in color. Some lenses have some characteristic letters or numbers, which must be seen correctly from the outside.

If the contact lens is placed upside down, then it is not going to cause any direct damage to the eye, just the comfort with the lens will be greatly reduced.
