Short-sighted and Near-sighted

Solution 1:

The NOAD reports that short-sighted is

• the British term for nearsighted
• the word meaning lacking imagination or foresight

Nearsighted is reported to mean unable to see things clearly unless they are relatively close to the eyes, owing to the focusing of rays of light by the eye at a point in front of the retina.

In American English, the words have two different meaning.

Solution 2:

Considering that Myopia and the adjective myopic can be used to refer to both the Ophtamalogical condition as well as the mental condition I think that you can feel comfortable using these terms interchangeably.

Solution 3:

According to my copy of the OED:
short-sighted adj. 1 having short sight. 2 lacking imagination or foresight.
near-sighted adj. esp. US = short-sighted.

Solution 4:

If you look at dictionary.com's definitions (nearsighted, shortsighted ), they do pretty much mean the same thing. I think "shortsighted" is used slightly more often to mean "failing to plan," but they can both be used that way.
