So I have just gone to get my eyes tested. At both places, they gave me an electronic test with that big machine that you stare into (at a picture of a house or road or something). They also both gave me the more traditional eye test with letters on the wall whilst trying out different lenses.
These are both highly respected chains. These are my results for Optician A:
(Left eye, Right Eye)
SPH -0.75, -0.5
CYL 0, -0.25
AXIS 170 degrees, 180 degrees
SPH -0.25, -0.5
CYL 0.5, 0
Axis, 180 degrees, 0 degrees
ie the results are almost completely conflicting. I originally guessed that one of them had filled out the form wrong by putting the results in for the left eye into the right eye box (and vice versa). However, on closer inspection, this could not be the case as the numbers are actually different anyway.
Anyway, I’m 25 and I’ve never worn glasses or felt the need to. With both of my eyes open, I have never strained to read, watch TV, drive etc. If I shut one eye at a time, I find that objects at a distance are blurry.
My question is, how accurate are these eye tests and do I really need glasses? One of the opticians told me that if I didn’t wear glasses, that my eyes might get worse. I have also heard the exact opposite before (ie if you do wear glasses when you don’t REALLY need to, then your eyesight will get worse).
My suspicion is that a high street optician wants you to buy glasses from their shop, and will be more inclined to say that they are necessary. However, I would appreciate the Straight Dope on the matter as this is highly perplexing issue. Apart from anything else, I don’t particularly want to have to spend $200 on lenses and frames.
