I went to a doctor for my eye checkup. And I couldn’t read the last line at all. Doctor said this is the limit to your eye and no matter how strong a lens, you would never be able to read the last line

Question

But I don’t get it. Why would if I put a stronger lens, I wouldn’t be able to read the last line? She said you must have never been able to read the last line in your life, and she was correct, but I don’t understand the science at play here

I doubt it is the main factor at play here but there is an actual physical limit to the ability of a lense to resolve different points based on the diameter of the lens. No matter how perfect your eye is there is a fundamental physical limit to what detail you can discern.
