Some people who need to wear eyeglasses face a conundrum when it’s time to choose new frames. Their eyesight is poor enough that without their glasses, when they’re trying on frames they can’t see what the new frames will look like.

What if optical shops set up a laptop on a counter or table and let their customers use the snapshot or video feature to capture their image with the various frames they like. The customer then puts their old glasses back on and views the images to help them decide which frames they want to order.
