text: I lifeguarded throughout the summer and was scared to use my $200 pair of ray bans, I found these on Amazon and they were great for wear and tare purposes. By the end of the three months of wearing them throughout the day they had little scratches but they got the job done. The fact that they are polarized helped a lot. They are very light because they are made out of all plastic but I didn't mind, I knew that by the end of summer I would probably toss them.
