Is it quick and easy? I want a few pair.
My ophthalmologist is selling them to his patients ($3,00 a pair). Receptionist says they have sold 600 pair. If you have an eye doc call him/her - if not- check with an eye glass store.
They really should be involved - also maybe the schools know where they are available.
Good luck.
Get two long boxes that will fit together. 1’x1’x2’ or so will do. Cut the tops and one end of each. Slide one inside the other. Pinhole one end and tape dark paper inside the other. Stand with your back to the sun, cover your head with the boxes, and adjust them to focus.
Watch out for scams. Google it and you’ll see.
Only 5 companies are approved by NASA but there are others that have good ones. Be careful of totally phony websites also.
Also, you must put them in front of your eyes while looking down, and then look down before taking them off your eyes.
There is going to be a lot of eye damage this time, so don’t be one of the sorry ones.
