Cheap sunglasses are next to use less, when it comes to blocking uv and harmfully blue rays, worth paying extra when I comes to your eye sight, I have damaged my eyes over the years, over 20 yrs window cleaning has took its toll,
I now wear Oakley flack jkt, blocks 100 percent uv and blue rays, they are light weight, and can swap lenses out in seconds, black iridium or polarised for very bright light, I swap to a lighter shade lense on overcast days, as even then you can still damage your eyes , constantly looking up from ground level.
Don't skimp on protection for your eyes.
