I go about heretically and happily uncorrected, but this is one thing I would not do - drive one-eyed. Depth perception is important when driving.
Right, I know. You are right.
I hold my palm up in front of the stronger eye. I can drop it. And make sure both eyes are focusing and working.
You can use wax paper or even a cleaning cloth, but your idea of a teabag is by far the most original I heard of
what if the dominant eye is more myopic than the non dominant eye? my dominant eye has sph 0.25 more than my non dominant eye. When I improve my dominant eye, do I also have to wait for my non dominant eye to catch up? do I also have to patch my dominant eye
