How do i know if my Transition glasses are transition and how do I test?

[Mohammed]

I just get my transition glasses in an optical store.But I don't know how to test whether they are transition lenses. Do you know any ways?

[Rhett]

Put on your glasses and go outside especially in a sunny day. If your glasses are transition glasses, they will turn dark.So you can tell by whether the lenses turn dark when they are exposed to the sunshine.

You can tell whether they change its color when they are exposed to the UV rays.

Well I'm on an eyeglasses site, and I typed in transitional and I don't know whether they are or not. And I won't know unless I order them and find out when they get here.
