Yep.. you are getting older and your eyes are more sensitive to light and are starting to fail you a little..the first time i had this I was on top of a mountain in oregon.. I had hiked almost a mile up and well.. it was getting dark which was no concern of mine and all of a sudden it was like someone took the focus out of my eyes and i had a shade pulled down..You can imagine my panic as i realised i might not make it off the mountain..
Well i took it slow and easy as there was no one else on the mountain to help me and I made it to the car.After the sun went completely down then it was ok..I get this a lot and was wondering are you at high altitude?? Even if you arent ,you can still suffer from your pupils expanding and retracting too quicky because of anxiety and nervousness and well when you go to the store you expect it to happen.I would get you a pair of lightly coated sunglasses something that will just keep your eyes at specific light.. and wear them..No one these days worries about anyone wearing sun glasess .People have become very aware of how easily thier eyes are damaged and wear sunglasses inside alot.. as for the popping in your ears could be inner ear or excess build up of wax..Get your gp to check it out and if they dont notice a problem then check with an ent ..If that doesnt solve it ask your dentist if you could possibly have tmj that is where the jaw is out of alignment and it causes the sensation you have.I have all of this and more some days it bothers me more than others and most days more but i squint and just grin and bear it but other days Its almost unbearable and riding through the mountains with the sun changing the shadows alot its kind of freaky and bothers me..But they say the combination of ears and eyes transmitting to the brain is what keeps the body in balance but try some of the things i have mentioned here and see if it helps..
