Three years ago before my husband was diagnosed he complained all the time about car headlights at night. Now he shuts his eyes if I'm driving home at night.
He got new lenses in his glasses in April because of a big change in his prescription for one eye. Then in October I took him back to the opticians as he could not see at all, if there was a shadow across the path when we were out walking and again a big change in his prescription but in the other eye. He is short sighted and the optician said not to get reaction lenses but for him to wear a cap when he is out walking and the cap has helped a lot.
