A PAISLEY-based opticians has shared some tips on how to prevent glasses steaming up when wearing a mask.

As mask wearing is now mandatory in shops and public transport, some Glaswegians have complained about having difficulty seeing when glasses have fogged up.

One person took to Twitter, with a photo, joking: “Canny believe a need to pick between breathing or seeing.”

But, Miller and McClure Opticians, based on Glasgow Road, have posted a video on their Facebook page informing those who wear glasses to put the mask on first and then their glasses on top.

Other tips included putting tissue paper along the top edge of the mask before putting it on and tying knots on the strings of the mask, so it sits on the face better.
