参加者が線を見分けることができたら、そのピクセル数まで目が見えるということです

If participants can distinguish the lines, they can see up to that many pixels.

これは、色によって目や脳の働きが違うからです

This is because the eyes and brain function differently depending on the color.

この研究は、4Kや8Kのテレビでも、普通の距離で見ると2Kのテレビとあまり変わらないように見える理由も説明しています

The study also explains why 4K and 8K TVs don’t look much different from 2K TVs when viewed from a normal distance.
