Lost Glasses

SHOOT! I lost my glasses. I haven't had time to looks for them for over 3 weeks since I was visiting my family in another country, and this is the second pair that I've lost. I lose my glasses 24/7, but after not randomly stumbling upon them for 3 weeks, I'm really scared. I feel really guilty since these glasses are expensive and my parents will have to buy new ones. I can see alright, and my power is only around -2.5, so it's not an issue of not being able to see. PLEASE HELP, I need to find a way to find them :(((( my parents don't have the money to keep on buying me glasses.
