I can’t survive without sunglasses. I’m sensitive to bright light, so every time I’m out in the sun for an extended period of time (over 30 minutes) without sunglasses, I get a headache. Sunglasses fix that for me, so yay. Unfortunately, since I also have bad vision, I need correctional lenses and sunglasses I like wearing can’t be made with correctional lenses. For now, I wear contact lenses and regular sunglasses over them. I’m considering switching to prescription sunglasses though.
