Good question! If glasses improved your eyesight your prescription should get lower over time, right? Then it'd make sense. You'd just get weaker and weaker glasses until they are gone... but when did that ever happen to you..? Exactly! So, why do they get stronger over time? Because optometrists regularly overprescribe... meaning you get glasses that are too strong. That's why you get the headaches with new glasses for 2 or 3 days... Your eyes just get used to the too strong glasses... So, why do you get glasses that are too strong? What most people fail to realize is that your eyesight is dynamic. It changes constantly throughout the day! You may have -2 (or +2, or a certain IOP, whatever... it all comes down to the same thing) in the morning. Then mid-morning have a really strong coffee with a lot of sugar and milk... So for 30 minutes your eyesight will be great. It'll be sharp. You'll feel great. You'll see crystal clear... so it'd be around -1 (+1, etc...) Then the sugar crash sets in... the caffeine wears off... and slowly your eyesight gets worse again... Back to -2... and then the liver has to deal with the sugar and milk... meaning, your eyes get less energy than they should... and now you are down to -3! (The numbers are arbitrary examples to illustrate the point. The same fluctuation happens with plus-glasses, eye pressure, astigmatism, eyestrain, floaters, etc) So, if you come to your eye test after the sugar crash, you'd get way too strong glasses this time around! There are many factors that influence your test:
- anxiety during the test (that you could get stronger glasses... the self-fulfilling prophecy)
- what you ate
- the eye drops making you nervous
- you feel pressure to get the test right
- a shitty night... lol
- fight with your spouse /boss/friend/coworker
- stress
- all kids had perfect vision for some time throughout the day
- NO child had perfect vision all day long!
- eat very light and healthy (salads and light snacks) all day before the test
- drink loads of high-quality spring water from a glass bottle
- have a strong coffee just before the test starts ;)
