If you buy cheap sunglasses without good UV protection, however, your iris will open up in order to let more light in, but not filter out the UV rays. Wearing cheap sunglasses can thus be more dangerous than not wearing any at all, so make sure your sunglasses have a label that says they offer UV 400 or 100% UV protection.
Put This On
I spent a fair bit on a good pair of sunglasses almost three years ago and I’ve never regretted it. I also put in a bit extra for the polarized version, which really helps with reflections while driving in a sunny place like Trinidad. I really struggle without them these days.
