  1. The sentence:

    Exposure to the sunlight had the effect of on your eyes.

    to me makes no sense – so the illustration/example is lost on me. Please refine the sentence, or, make it a sentence.

    Thank you.

    • I think it was their typing mistake
      It should have been like “Exposure to the sunlight had an effect on your eyes”

  2. Excellent (again)! I do not bother researching other websites for info., I go right to http://www.differencebetween.net.
