Accommodation:
The process in which the lens (ciliary)
muscles pull the internal lens into a rounder shape, giving it greater
light-bending properties. People who have normal vision must do this to focus on
objects closer than 20 feet from them, people who are nearsighted must do this
to focus on objects much closer (how close depends on the degree of myopia, but
myopes’ ciliary muscles are relaxed at 20 feet and some distance closer, since
pulling the lens into a rounder shape would only worsen their distance vision),
and people who are farsighted must do this to focus on anything and to a greater
degree than emmetropes would have to. Prolonged, intense accommodation (reading
with the book too close for prolonged periods for emmetropes, doing just about
any close work at all for uncorrected hyperopes) can cause eyestrain (the
“eyestrain” experienced by uncorrected myopes is probably more likely general
strain of the muscles surrounding rather than inside the eyes, caused by
squinting, it does not appear that the ciliary muscles can accommodate “in
reverse” by making the lens flatter, as would be necessary to “accommodate” for
myopia). We are born with the best accommodation we will ever have (much more
than we need, unless you’re very farsighted) and as we grow older we gradually
lose it until around middle-age, the arms suddenly become too short to read the
paper (this condition is presbyopia)!

Myopia/nearsightedness/shortsightedness:
-0.25 to -2.75, mild/low myopia, people with this degree of myopia can generally manage fairly well without correction, except for tasks such as driving, blackboard reading and movie watching which require sharp distance vision; these people can often be observed squinting while performing these tasks uncorrected, glasses for this degree of myopia are concave in back with a slight convex curve in front.
-3.00 to -5.75, moderate myopia, people with this degree of myopia typically wear correction full-time and consider themselves dependant on it, they are still able to read and perform close-work uncorrected but things like navigation, picking up visual cues for social interaction and at the higher end of this category, even intermediate-distance tasks like computer work are difficult; a fairly continuous squint is often present when bare-eyed, glasses for this degree of myopia are concave in back with a slight convex curve in front.
-6.00 to -9.75, severe/high myopia, people with this degree of myopia have great difficulty performing any visual work uncorrected, even reading is challenging, this is the level where many myopes stop squinting because it no longer makes any significant improvement; this is also the beginning of high myopia and persons in this category run a greater risk of retinal tears and/or detachments than the non- or mildly myopic, glasses for this degree of myopia are usually concave in back with a plano-front.
-10.00 on up, very severe/high myopia, people with this degree of myopia are functionally blind without correction, the range of clear vision is limited to a couple inches in front of the person’s eyes, very high myopes have an even greater risk of retinal complications than lesser high myopes and many very high myopes can‘t achieve 20/20 even with correction, due to thin retinas and/or the minification of the glasses themselves (in this case, the vision is better with contacts) (although many very high myopes do see well with their glasses and never experience retinal problems), glasses for this degree of myopia are usually either biconcave or (for extreme cases) myodisc.
Hyperopia/hypermetropia/farsightedness/longsightedness:
+0.25 to +2.75, low/mild hyperopia, people with this degree of hyperopia can usually manage fairly well uncorrected, except for reading and other close-work (if the low hyperope is young with good accommodation, even close vision may be clear, though he/she likely will experience some eyestrain), squinting can be helpful for mild hyperopes as it is for mild myopes, but is less characteristic of hyperopia.
+3.00 to +5.75, moderate hyperopia, people with this degree almost certainly need glasses to read, even if young and typically experience some distance problems as well, unless their accommodation is very good.
+6.00 to +9.75, severe/high hyperopia, close-work uncorrected is out of the question and distance vision is almost as bad as it is for a myope of corresponding degree (up until this point, hyperopes tend to be less glasses-dependant than their myopic counterparts, due to good distance vision and the ability to obtain good close vision by focusing effort, but at the severe levels, myopes tend to do better, since at least they can see what’s right in front of their eyes, while nothing can be far away enough to be in focus for a high hyperope).
+10 and up, very severe/high hyperopia, people with this degree of hyperopia are functionally blind without correction and while they don’t have the retinal complications or minification problems of high myopes, they often have problems related to the distorted view of things through strong plus lenses, including peripheral vision problems (though, like myopes with minification troubles, these hyperopes often see better with contacts, which cause less distortion), also, it seems that very high hyperopia is even rarer than very high myopia and many of the cases that exist are due to surgical removal of the internal lenses, so there are even fewer “natural” very high hyperopes, glasses for this degree of hyperopia are sometimes made in a lenticular lens design, like myodiscs for very high myopia, except in this case the center “bowl” is a super-strong plus lens.
Astigmatism:
Presbyopia:
Emmetropia:
This means NOT having a refractive error,
having normal vision, not being lucky enough to need glasses; very few people
are actually perfectly emmetropic in both eyes (most could use at least a
quarter diopter of plus or minus in one eye or the other), but glasses are
generally considered unnecessary if the person can achieve 20/20 or 20/40 visual
acuity; most OOs regard these unfortunate souls with great pity :;-).
Rx/script:
OD -4.50 OS -4.00 (this is my rx, I have 4 and a half diopters of myopia in my right eye and 4 diopters of myopia in my left, it only has one set of numbers because I have no astigmatism)
OD +3.25 -.75 axis 105 OS +2.50 -1.00 axis 84 (this person has 3 diopters of hyperopia and three-quarters of a diopter of astigmatism in their right eye and 2 and a half D of hyperopia and 1 D of astigmatism in the left eye
OD -7.00 +.50 axis 68 OS -7.00 +1.50 axis 71 Add +2 (this person has 7 D of myopia in both eyes with half a diopter of astigmatism right and 1 and a half D astigmatism left (written in plus terms since this person got their rx from an ophthalmologist instead of an optometrist) and needs either a bifocal segment or a pair of reading glasses with a power of -5 (-7 + +2= -5)
OD -3.00 -.75 axis 52 Prism 5D BO OS +4.25 -.50 axis 56 Prism 5D BO (this person is myopic in their right eye and hyperopic in their left (yes, this is possible, though not common) with a bit of astigmatism in both and some base-out prism correction for crossed-eyes)
Visual acuity/acuity:
Ambilensdrous or Bi-lensual, term coined by Lenslover, Eye
Scene website, Poll 19 (Glasses fetish), 31 August, 1997:
OO who is attracted to both thin and thick lens glasses or OO who
is attracted to both myopes with minus glasses and hyperopes with plus glasses
(it appears that “Ambilensdrous” is intended to refer to the thin/thick
distinction while “Bi-lensual” refers to plus or minus).
Bare-eyed, term coined by Susanne, Eye Scene website, Poll 81
(Glasses and personality), 26 February, 1999:
Going without one’s glasses,
often as a challenge, to relax in the softness of the blur, or for erotic
purposes.
Cut-in, term of uncertain origin, first used on Eye Scene by
Bergerac, Glasses are sexy thread, 13 Jun 2002, also in Likeglass’ “Glossary of
Glasses Loving Lingo” though I don’t know whether or not this predates the Eye
Scene usage:
The part of the wearer’s face surrounding his/her eyes that is
covered by the glasses appears smaller or shrunken in comparison to the rest of
the face, the curve of the face in this area seems to curve “in“ towards the
wearer‘s nose; with fairly strong lenses this often means that when viewing the
wearer head-on, he/she may actually appear to have four ears, as well as four
eyes (in OO culture this term is a compliment, not an insult) )!
Cut-out, term of uncertain origin, first used on Eye Scene by Singa, Strong glasses thread, 04 September, 2003, though the way he uses the
term here suggests it wasn’t new to him at that time:
The part of the
wearer’s face surrounding his/her eyes that is covered by the glasses appears
larger or magnified in comparison to the rest of the face, the curve of the face
in this area seems to curve “out” towards the wearer’s ears.
Emoticons for glasses: 8-) or 8) smiling with glasses
8-( frowning with glasses
:: ) smiling with glasses (:: means 4 eyes)
:; ) winking through glasses
8;) pushing glasses up to forehead then winking
(((o)))--(((o))) small eyes behind strong minus glasses with power rings
|-), squinting without glasses, though this would probably more likely be |-(
:|-( or 8|-( squinting WITH (too weak) glasses
GOC, term of uncertain origin, first used on Eye Scene by Lenslover, Poll 69 (Eye Scene FAQ), 7 November 1998, also in Likeglass‘
“Glossary of Glasses Loving Lingo” though I don’t know whether or not this
predates the Eye Scene usage:
Acronym for Glasses Over Contacts, the
practice that some OOs who want to wear glasses but don’t really need them (or
who want to wear glasses of a different (usually stronger) rx than their natural
one) have of wearing glasses of the rx they want over contact lenses of the
opposite rx (for instance, -3 glasses and +3 contacts), so that they can see
clearly out of the glasses. (also see
What is GOC)
GWG, term coined by LikeGlass (unknown date), first used on
Eye Scene website by Chris (Wurm), Poll 11 (Eye doctors/opticians), 23 June,
1997, referring to LikeGlass’ site by that name:
Acronym for Girl(s) With
Glasses, some feel this term is sexist (referring as it does to grown females as
“girls”), especially considering the masculine equivalent in most common usage
is “MEN in Glasses“, but with the alternatives being “WWG” (Women With Glasses)
and “WIG” (Women In Glasses), it is perhaps understandable why GWG is the
standard term.
Hi-my, term first used by LikeGlass, Eye Scene website,
Sightings thread, 20 October 2002, there were previous uses of “Hi-myope” by
others:
High myope, someone with a glasses rx of at least -6 diopters.
Holy wowsers, term coined by Filthy McNasty, Eye Scene website,
Poll 25 (Prescription changes), 24 October, 1997:
1. Exclamation, expression
of astonished awe, similar to a cross between “Holy hot dog, Batman!” and a
“Tweeeeeet TWEET!” whistle. 2. Noun, referring to a pair of spectacles which
tends to elicit such a reaction in an OO.
Hyper halos, term coined by me, just now 8-):
Reflections
of light from plus lenses that make it appear as though the lenses themselves
were glowing, which is hard to explain and lacked an adequate descriptive word,
but can also be observed (though not nearly as beautifully) in a magnifying
glass.
Induced myopia:
A process by which a person hopes to make
him/herself (more) myopic by doing a number of things that anecdotal evidence
suggests can increase myopia, including reading a lot while holding the book as
close as possible, doing lots of computer work and wearing minus glasses that
are stronger than the person's real rx, if any.
MIG, term of uncertain origin, appears to have been coined by
Electra, uncertain date:
Acronym for Men/Man In Glasses, this is the
standard term, though I have also seen “BWG” (Boys With Glasses) and the term
“GyWG” (Guys With Glasses), used by LikeGlass in his “Glossary of Glasses Loving
Lingo”, appears to be the earliest term to be used to describe bespectacled
males.
Optic-obsessive/OO, term coined by Lenslover, Eye Scene website, Poll 22 (Other people’s glasses), 28 September, 1997: Person with a passion for eyeglasses/vision defects, also called Specs-, Glass- or Lens-aholic/Lenshound/Glassophile.
Hypermyophiliac, term coined by Dr. Bob, Eye Scene website,
Thought of the day thread, 31 May, 2002:
One who loves very nearsighted
people-hyper=much, very; myo=myopia, nearsightedness; philiac=one who loves, is
attracted to/aroused by.
Myophiliac, term coined by me, just now, based on Dr. Bob‘s
“hypermyophiliac” :

Autohypermyophiliac, term coined by me, just now, based on Dr.
Bob’s “hypermyophiliac”:
One who loves/enjoys/is aroused by his/her own high
myopia (either real, simulated (for instance, by GOC), or only in fantasy (they
like the IDEA of being very nearsighted, but wouldn’t necessarily want to be for
real).
Automyophiliac, term coined by me, just now, based on Dr.
Bob’s “hypermyophiliac”:

Power rings, term of uncertain origin, first used on Eye Scene
by Doctor Bob, Poll 61 (Glad for glasses?), 18 August, 1998, though the way he
uses the term here suggests it wasn‘t new to him at that time:
White
concentric circles of reflected light that can be seen along the edges of minus
lenses (giving a kind of “bulls-eye effect”) when they are looked at from an
angle other than head-on, for instance when the wearer looks down or off to the
side, which increase in number in proportion to the lenses' strength.
Scatter my datter, term coined by Filthy McNasty, Eye Scene
website, Poll 32 (Accessories), 11 December, 1997 (in this case and often
thereafter, this is used in it’s complete, formal form “Scatter my datter she
cernly lookit well”):
An expression of admiration, kind of a McVersion of
“That’s hot!”.
Spexy, term coined (as “sexyspexy”) by Jennifer, Eye Scene
website, Poll 26 (Glasses and personality), 3 November, 1997:
Sexily
bespectacled; some of us who are turned-on by glasses say that we “spell sexy
with a p”.
Tilting, first used (as “tilt”) on Eye Scene website by MIKE,
Poll 20 (Eyesight), 14 September, 1997, but based on an experience of Gayle, Eye
Scene website, Poll 2 (What frames do you wear?), 19 April, 1997:
I think
Gayle’s aforementioned post explains this best: “…Because my prescription was
outdated, I was in the habit of wearing my glasses with the ear pieces above my
ears instead of behind them on those occasions when I needed to see at longer
ranges. For whatever reason, changing the angle of the lenses to my eyes and
pressing them closer gave me better vision. …” This “wearing one’s glasses above
one’s ears” in order to compensate for a too-weak prescription is called
tilting.
Tuggers, term coined by Hayes, Eye Scene website, Poll 27
(Multiple pairs), 8 November, 1997:
Glasses with slightly more minus
correction than one’s actual script calls for, used to give extra long-distance
clarity for, for example, night driving, or to try to keep up with rapidly
increasing myopia without need for constant lens changes, though in the second
instance some say it increases problems in the long run by accelerating the
myopic increases.
