I think he would notice if his eye sight was getting worse. Give him some credit.
Depending on the distance a person is viewing a 22" 1920x1080 monitor, you may need to have 20/20 vision (considered to be "perfect vision") or better to be able to read small text.

, vision loss can be very subtle and you may not realize your vision has degraded minutely until you test your vision. For example, earlier this year I went for an eye exam, the optometrist told me my vision has deteriorated slightly from around 2 years ago. However, it's not at the point where it needs to be corrected.
