I've always wondered how different this variety is from the species, which abounds in our forest. Can anyone compare?

I have several containers of old buttons. Could you post a picture for us to see?

My best fried in IL lives in one almost identical to the yellow one in Glen Ellyn, IL, right down to the color, turret, and wrap around porch! Unfortunately, it has it's 'issues', but doesn't every pretty girl? Lol

RN, They aren't narrower through the bridge, comparing them to my "regular" eyeglasses, but the nose bridge piece extends a little bit further, so there's more of the piece to sit on your nose. It's hard to explain, but if a store near you sells the same style in regular and Asian Fit, try them both on and see if you notice a difference in how they sit on your nose. Of course, either way, the optician should be ensuring the ends of the arms of your glasses have a slight bend downward around your ear, which is done for the fitting, to ensure they'll stay on better. Also, if your hinges have become loose and there's too much play in the arms, of course they'll be prone to sliding down. But if even brand new glasses fitted for you don't stay up well, you may find it resolved by the Asian Fit ones. The optician told me that he often recommends them to anyone who complains that no plastic frame glasses sit properly on their nose. My daughter got Versace Asian Fit glasses as they also fit her better than the Versace regular. http://www.smartbuyglasses.com/designer-eyeglasses/Versace/Versace-VE3205BA-Asian-Fit-GB1-261658.html
