Hi Syed,
If you click on the People tab at the top of the webpage and search in the keyword search for optical, eyeglasses, etc, you can see what other people in your industry might have labeled themselves as.
The Health/Wellness category looks like it's the best fit based on what is in the drop-down list. But if you have suggestions for another category, there is a link when you're editing your entrepreneur profile page to "suggest a missing industry". They may not be able to put something as specific as "optical industry" in, however.
Take care,
Anu
