Abbe Value of Eye

[sportywei]

Hi guys,

I understand that Abbe Value one of many differential factors of determining choices of lenses.

Recently, I got to know that Abbe value of our human eye is 45.

1.How is the value determined?
2.Does the value correspond to our cornea, crystallaine lens or as a whole?
3.Just like to enquiry how would Abbe value of eye affects the image quality we see?

Cheers:o

Good but tough questions.

I've never heard a human say that they experience their eyes' chromatic aberration.

I think it's safe to use the 45 value (or whatever) as a maximum value...in other words 45 and up are all perceived the same.

It may be useful, also, if we were to devise some scale by which to rate lenses according to an absolute (vs. relative) standard. For example, a material having an abbe of 32 would be 71% efficient, and another material at 36 would be 80% efficient.

I would assume it is determined experimentally (perceptually) rather than optically measured, and it would therefore apply to the human optical system as a whole.
