i’ve bought 50-60 pairs of these readers over the years. good value. they last until you put them in your pocket and the cheap plastic frame breaks. i don’t mind because they are so cheap, but today i think i’ll try another brand.
these glasses don last long, the frames crack near the nosepiece because the lenses are too tight in the frame. don't expect them to last and do bot expose them to cold or hot ambient temperatures
these glasses worked fine (though not as clear as i'd like) when i lived in san francisco, which has cool weather. i moved to florida, and left two pairs of reading glasses in the garage. when i returned three weeks later, the frames on both were cracked due to the warm weather. one was cracked in two areas, and another was cracked in one area. the highest temperature for the month was 90 dgrees, with an average of 82 degress. so i do not recommend these if you get relatively hot weather.
