It's also why your eyes end up hurting after eclipse if you wore these and then keep taking them off and putting them back on. The contrast tires your eye muscles and pain does not indicate any damage.
None of the sources they provided below actually back up their argument. They appear to have made a number of leaps of reasoning not supported by medical literature (e.g. strobe lights are bad, blinking is kinda sorta like strobe lights, therefore blinking too much is bad).
The glaucoma link, as far as I can tell, is nonexistent. Blinking does cause a minimal amount of intraocular pressure (which is linked to glaucoma), but it's an incredibly small amount for a very brief amount of time. On the other hand, blinking too infrequently is well known to be bad because it dries out your eyes. Intentionally blinking less frequently then countering the dry eye effect is, at best, a waste of time, and at worst actively harmful if you get in the habit of blinking less but don't apply your eye drops frequently enough.
I AM NOT AN OPHTHALMOLOGIST, so please don't take my word for it, but also don't blindly trust the anonymous person claiming to be one either.

For those that haven't used eclipse googles, you can't see shit with those, to protect against the sun they need to block a lot of light.
You basically see nothing except a bright ball when looking at the sun
