Why there is a line in my glasses lens?

[Messiah]

I found there is a vertical line near the middle and it is only in the right lens.It doesn't seem to be a crack.so should I take them back to get them fixed?They are not bifocals.

[Semaj]

It sounds quite strange for they are not bifocals and haven't been cracked. You'd better take them back to the store where you have bought them and check if there is something wrong with the coating.

[Triston]

Since you are sure they are not bifocals and not a crack, it may be something wrong with your glasses. You should take your glasses back to have them checked.
