Is that true?

Sailor here. At night you keep the bridge dark, but there will be a light at the chart table and a curtain surrounding it. Some do cover one when checking the chart to retain night vision but its pretty rare. Once you eyes have adjusted to the dark, a minute or so in the light doesnt equal the 20 minutes it can initially take to get your night vision on. No idea about actual pirates and patches though

No, they wore eye patches because it was stupidly easy to lose an eye in naval combat back then.

Most casualties in a battle would be due to flying splinters of wood from cannon balls striking the hull, and medical care on the high seas was almost nonexistent. If even a small splinter stuck into your eyeball, you'd lose the eye.

supposedly it was something they did before boarding
