In response to Kristy Prince: if you don't wear photochromic lenses or sunglasses, your eyes will have to adjust to the light, causing fatigue. Furthermore, UV radiation from sunlight may cause damage to your eyes. Photochromic lenses are recommended because they adjust for you, reducing fatigue while providing protection and convenience.
