Adjustable Strength Beer Goggles

there are already glasses that use a special pressurizing system to implement water based adjustible eye glasses. they are designed to be cheaply made for people in developing countries who need optical aids.

instead of water, my line of glasses uses beer in order to adjust prescription strength. the beer would work as a tinting mechanism as well. depending on the brightness on any given day, you can adjust the contents of the lenses for beer darkness. bright days would allow for darker beers.

special edition goggles will also contain a small, battery-operated cooler, so your backup supply of intoxication beverage would remain cool.
