Most of us use glasses every day. Those blessed with 20/20 vision sport sunglasses and lift drinking glasses. Those who need corrective lenses to experience anything close to 20/20 eyesight have a spending category labelled prescription glasses. For this month's PBC theme, I aimed to take photos of many different kinds of glasses. I didn't get any of magnifying glasses or rose-coloured glasses. Take a look through and let me know what else I missed.
