Is there such a thing as curtains that can block out the sun but still be seen through

I work in a small business where the front is 10 feet high glass panels.
In the morning the sun is beeming through and it causes the area to heat up a lot
I've been looking and wondering if it's possible to find curtains or blinds that can help stop some of that energy but still allow customers to see through the inside of the store at least somewhat.

E: Thanks for the info everyone. Looks like I got a few options I can look into now.
