I bought these 2 weeks or so ago for a week long tour of Scotland, I covered 1500 miles in these glasses and found them to be comfortable and bother free. I had no idea if the lenses were yellow or tinted, they just take care of things and keep the dazzle at ease. No change in colours as they change that I noticed, did the job well. I normally struggle with sun glasses taking them on and off constantly as the light changes. Left these on all day no bother. Good lenses, well packaged, arrived quick. Good quality for the very reasonable price!
