Good quality and evalue, but NOT sunglasses
Used for More than 2 years
These yellow lenses are really good for dusk or dim days. They are not sunglasses though, they do not cut out light or protect the eyes from UV. They appear to make it brighter so you wouldn't be wearing them in sunlight anyway.

I always wear eye protection when cycling since getting some grit in my eye and ending up in A&E to get it removed. Plus, they stop any branches of other unexpected things entering the eye, especially off road in the dark.

I have had plenty of these, they last well and are visually very good. Cheap enough to stuff in a pocket or rucsac and not worry about damaging them, although I have rarely broken a pair as they are very resilient.
Must have

Amazing value for money!
Used for 2 to 8 weeks
For the price, these glasses are excellent. Close fitting comfortable and cheap. In winter they are liable to steam up whilst stationary. Perhaps anti fog coating would help this but I wouldn’t expect it at this price and it’s a minor annoyance.
Good for bike riding.

I got these to protect my eyes from flys. My sunglasses do the same job however when driving through forest the sunglasses make it hard to see tree routes. The yellow glasses actually enhance your vision in shaded light.
great value for money
