Issi...it is a good plan to have an eye-test as the optitians do check for Glaucoma and other diseases. Lucky you to not need glasses though...Congratulations! I have never been pressured into having glasses from where I have the test. I think they are not allowed to do that. You can take your prescription to any other optitian even if you are advised to get glasses....and you do not have to have any if you feel you do not need them.

Mayday
