Make a respirator mask compatible with glasses

Modified a Lab respirator mask so prescription glasses could be used without wings. The wings of the original glasses created a gap between the seal of the mask and Fiona's face letting the harmful chemicals in. Thanks to Sugru Fiona's glasses are fitted in the right position and now no chemicals can get in! I had tried other products to secure the glasses but they didn't work due to quick curing times or poor strength!
