Fit: Best for small to medium sized faces.
I have a pair of glasses that I bought off Amazon, and these Dunes blow the Amazon pair out of the water. The Dunes are so comfortable and fit very nicely on my face. They are wearable all day without displacing lights or causing any headaches. I highly recommend this pair as a cost effective option for someone who wants to save their eyes from some computer strain.
