A normal eye falls within the diopter range of - 0.50 to +0.50.


This was posted elsewhere in response to someone. His reply was totally false and I am correcting him!


You have much to learn.


"A normal eye falls within the diopter range of - 0.50 to +0.50."

Sorry but anything within - 0.50 to +0.50 is considered emmetropia and normal. Its not even factored in the tally of percentages of people with "defective vision" I can show you an example by another optometrist who posted here.

You're getting close. -6 IS something, -22 is VERY extreme, and -10.25
is high.

I'd say, roughly, shooting from the hip, that:


trace myopia is between -.12 and -.50
low or mild myopia is from -.75 to -3.00
moderate myopia is between -3.00 and -7.00
high myopia is between -7.00 and -12.00
pathologic (or extreme) myopia is above (approximately) -12.00


In trace myopia, you never see organic/structural changes related to the
myopia, and it is often not really myopia at all, but ciliary tonus.


I agree with William! Like I said, up to -.5 is not really myopia at all! Low myopia starts at -.75


""Neglectable"??!"

At his -.5 pescription, it didnt really make a difference with or without glasses. I dont care what you say, seeing just shy of 20/20 is not considered having trouble seeing. I would not even consider 20/40 trouble seeing except in extreme situations like if I wanted to be a pilot, join the army, be a spy or anything that requires 20/20. I consider trouble seeing starting at 20/70 to 20/100. My brother is 20/60 and he can see just fine. I have pointed out things in the distance and hes able to see almost anything he wants. He only wears glasses for driving and occasionally to see lectures in college classes.


By the way, I know of no one(in person) less than -1 who wears glasses. Less than -1 sometimes is referred as "fractional myopia" or as William put it, not really myopia but ciliary tonus. My sister actually got her first pescription at -.75 and she tried the glasses once and remarked she couldnt really see a difference and hasnt worn glasses since. Her eyes got worse because of all the near work she did then when they got bad enough she really did need glasses but soon switched to contacts.

He has said he often goes without correction, especially on the weekend. Nothing wrong with him wearing glasses for driving at night and for his presbyopia. I still stand correct that he sees fine without glasses and is why he goes without them much of the time, especially on the weekend. His optometrist even said he has VERY, VERY mild myopia. He is still within the normal +0.5 to -0.5 diopters, at least in one eye. The vast majority of people are asymptomic with -.5 diopters and never even think about glasses much less go out and get glasses. There are a good number of people seeing 20/20 or 20/25 at -.5 and they think nothing about their vision, as its perfect. Heck, I see worse with my BCVA glasses than most people see uncorrected at -.5 diopters. I have simulated what -.5 diopters is with my older glasses which are -.5 diopters too weak. I can barely tell the difference. Everything has a very, very slight blur and loss of contrast but is still nice and clear and I have no trouble seeing anything. Of course there are some super, super picky people who are perfectionists and wear glasses for the miniscule -.5 diopter "myopia" they have. For just about anyone else, it simply isnt worth spending money and time and the hassles of dealing with glasses

I respectfully disagree wholeheartedly. I AM myopic. My eye doctor told me I am. My prescription is -0.50 for each of my eyes. I do wear my glasses all of the time. Therefore, you do know one person under -1.00 who does wear glasses. As I filled out in my survey on this site, I feel blind as a bat without my glasses on. I am a myopic with a -0.50 prescription.
