Tired of paying those ridiculous prices for a small bottle of eye glasses cleaning solution? Make your own! This is the "Ed's Red" of eye glasses cleaners.
3 oz - water (tap is ok, distilled is preferred)
1.5 oz - 91% or 99% Isopropyl alcohol
5 - 10 drops liquid detergent - Start with the lesser amount) You can use the "Softsoap" brand "antibacterial" clear liquid hand soap, but Dawn dish detergent which will give your solution a little color and really cut lens grease, is the best.
Fill your old spray bottle and shake well. Allow to sit till the foam dissipates before using . To clean your glasses, rinse them with warm water to remove heavy grit and dust, spray with the cleaner, let sit a couple of seconds, rinse with water again, and wipe dry with a clean, soft cloth (the micro-fiber cloths are particularly good). The second rinse removes the dirt and the soap.
NOTE: While you can use this solution on camera and scope lenses DO NOT spray directly on the lenses.
Blow any heavy dust off the lens and then spray the solution on a soft lint free or microfiber cloth, and then clean.
If you have REALLY grimy glasses, use warm running water to rinse off any gritty smutz (a technical term for crud on eye glasses) and put a couple of drops of Dawn dishwashing detergent on each side of the lens, add a couple of drops of warm water, and using your clean fingers gently rub the lens surfaces and the edges of the lens (you'd be surprised how much stuff is on the edges of the lenses and frames) for a couple of seconds. Rinse thoroughly with warm water and dry with a micro-fiber cloth.
Thanks to Dr. John for this tip.
hm: I have found that CLEAN glasses don't seem to fog as badly as "not so clean" glasses. Mine are often "not so clean". LOL
I just spray, wipe and shine with a micro-fiber cloth. But I do wear GLASS lenses.
