How do I explain that reading a concave meniscus above water level will lead to a lower than accurate reading?

I have this pre-lab question that I need help with. All i can find online is that if you read you must read at eye level to get accurate measurement. OK, I get it. And I read that if you read above eye level, the reading will be lower. If you read below eye level, the reading will be higher.

But WHY? Without just saying parallax error? How can I elaborate it a little be more then just plugging in a fancy phrase because of "parallax error".

Basically, how do I articulate an explanation as to why reading above eye level lead to lower water volume reading? What is it about reading from above that prevent an accurate measurement? I hope this makes sense.

Thanks!

You could just condense and adapt the information from resources like WIKI
or the sources mentioned in the WIKI.

Someone who is an undergraduate would be expected to do research and write up the results.
