I gave up sunglasses about 3 years ago when I learned this. The eyes adjust very quickly. It is amazing how much I enjoy seeing the world in real light. The only time I wear sunglasses is if there is harsh glare while driving to be safe, and in snowsports like skiing in bright sunlight. It is quite relaxing, and you can wear a hat or visor as well to help as you get used to going without sunglasses. 😇
