I’ve had similar for a few years. The optician told me it was dry eyes. And once diagnosed type 2 was further told it’s not unusual for us. It hasn’t gone completely it is much better than it used to be since I got control. There are sprays and drops available over the counter to help that might be worth a go. Massaging over closed eyelids helps “warm up” the lipid coating and tear ducts as will a warm flannel both speeding up the clearing.
Its also common when reducing bgl quite quickly but only lasts a few weeks til your eyes get used to new better levels. Don’t buy glasses just yet if this sounds likely. Cheap as chips readers if you need them off the shelf to tide you over for close up work.
