I bought it for bicycle commuting. I usually put on a clear glass. There is a feeling that it is being pressed slightly whether the part that is applied to the ear is not on the head, but it got not worried so much if it got used to it. Also, insects may enter somewhat from the upper side of the eyes in the summer. I think that it is enough as a price.
A good point with the feeling of use is that you can replace the lens, that there is a clear lens, the temple stretches, and you can tilt the temple up and down. What you want to improve is that you want the locking power of Temple stretching to be a little stronger. That's all.
