How to say "short-sighted" in Japanese

• 浅はかあさはかCommon
  na-adjectiveCovers 'short-sighted' in the sense of shallow, thoughtless judgment that does not think things through. Typical of criticism of hasty decisions, plans or remarks.
  私はあさはかにも彼かれが私を助たすけてくれるんだなあと思おもった。↗

  I foolishly imagined that he was going to help me.
• 近視眼的きんしがんてき
  na-adjectiveThe closest fit for 'short-sighted' meaning lacking long-term foresight: seeing only what is immediately ahead. Said of thinking, policies or strategies that ignore future consequences.
  イギリス人いぎりすじんと比くらべてみると、我々われわれは近視眼きんしがん的てきすぎる。↗

  Compared with the English, we are too near-sighted.
• 単眼的たんがんてき
  na-adjectiveReally describes viewing things from a single angle — narrow-minded — and 'short-sighted' is only a marginal rendering. Seldom the word you want for lack of foresight; for that sense 近視眼的 fits better.

Use 「浅はか」 for shallow, thoughtless judgment, 近視眼的 for lack of long-term foresight, and 単眼的 mainly for a one-sided viewpoint, for which 'short-sighted' is only a loose rendering.
