The brain automatically smoothes our visual input over time. Instead of analyzing every single visual snapshot, we perceive in a given moment an average of what we saw in the past 15 seconds.

Yes, when you look at the Sun, you are seeing it as it was about 8 minutes ago because that's how long it takes for sunlight to travel the ~93 million miles (150 million km) from the Sun's surface to Earth, making the Sun an 8-minute-old image of itself. This means if the Sun suddenly vanished, we wouldn't know for 8 minutes, as the last light would still be heading our way. This "lookback time" applies to everything in space; the further away an object is, the further back in time we're seeing it.How far can you see until the Earth curves?

No, a -7 prescription itself doesn't automatically mean someone is legally blind; legal blindness depends on your vision with the best possible correction (glasses/contacts) being worse than 20/200, or having a very narrow visual field (20 degrees or less), not just the prescription number. A -7 prescription indicates severe nearsightedness (high myopia), but if those glasses correct your vision to 20/20, you aren't legally blind; however, if your vision with the -7 glasses is still 20/200 or worse, you would be considered legally blind, notes this Quora answer and this Reddit thread.Can you see 30 miles away?
