LPT for losing your glasses to be able to see to find them.
Assuming you have a cell phone open your camera app and then you can hold the phone near your face and it will show you whatever is in front of you. You can use the camera to look around for your glasses. I have absent-mindedly set my glasses down on my dresser or in my bathroom before bed then forgot where I put them in the morning! Also good if your glasses get knocked off the bedside table or get dropped somewhere. #entertainment source
