A post explains "right here" this way
is usually used when the location is very specific, within reaching distance, and can be pointed to directly
which uses the phrase "within reaching distance"
In another post ("here" vs. "over here" in an area of an eye), a contributor uses a similar phrase
In simple terms, 'over here' means 'within your reach'. Over here means near you - From Collins English dictionary.
I guess "within my reach" and "within my reaching distance" mean the same thing.
inside or not further than an area or period of time
I guess "reach" in this context means "see", the whole thing means the whole area I can see.
Given the post is based an image of the surface of an eye, "within my reach" means the whole image/screenshot, is my understanding right? Could someone please give a hint? Thanks in advance.
