Did you know that cystinosis causes crystals to form in the eyes and can cause light sensitivity and even blindness if special eye drops are not taken hourly, which is almost impossible. This leaves many people with cystinosis sensitive to light and sometimes needing to wear sunglasses even indoors. Today is Cystinosis Sunglass Day and we'd love it if you showed your support by posting a sunglass selfie and spreading the word about cystinosis! #cystinosissunglassday
