I love my Axon Optics Kula indoor migraine relief glasses I won last Fall through VEDA (Vestibular Disorders Association). So, I wanted to get an outdoor Kula pair to make being outside in the bright sun a bit easier for me. It took a day to adjust to them, but they are awesome! They have the best anti-glare I've ever seen and are great for sunny days, as well as cloudy days (when regular sunglasses would be too dark). Most importantly, they seem to be helping with my photophobia/light sensitivity.
I highly recommend these glasses and Axon Optics for anyone with headaches, mIgraines, or light sensitivity.
