Apophenia

*ponders lasik (wants custom lasik, but vision too bad for it, but maybe regular lasik first then custom later if needed)*

*ponders implants*

i should put some pressure-sensitive thingy on the edge of my desk to trigger an annoying sound if i'm leaning on my arms. they get hurty after a while. i'm in theory training my eyes by putting the monitor farther back and having to focus on it, but in practice i lean forward to see.

i should reprise myself from 2004 march:

Patient: "Doc, it hurts when I do this..."
Doctor: "Well then don't do that!"

Depression Patient: "Doc, it hurts when I do nothing."
Doctor: "Well do something then!"

I go to bed at 7am. I wake up at 2pm.
I go to bed at 11pm. I wake up at 2pm.
I hate my body.

I had my doctor write me a prescription for exercise.

That way, I have to do it. Doctor's orders.

All my tests come back completely normal which means I don't actually have periodic neck pain and I'm not really tired all the time.

I've spent about 18 of the last 24 hours asleep.

I hereby officiatedly note my glasses prescription:

and also note that glasses and contacts have different prescriptions...so ”9.00 diopters for glasses is not the same diopters that contacts would have. Flurgle.

Right Eye:

–11.00 diopters (degree of spherical nearsightedness)
–1.00 diopters (degree of astigmatism: ie, i'm -11 in one direction and (–11) + (–1) = –12 in another direction)
85° axis (angle of the above "another direction"; 180 = horizontal, so presumably this would most properly be 90)

Left Eye:

–11.00
–1.00
70°

Misc scrounged info:

A diopter is a unit of measurement of the refractive error. It may be a negative number (myopia, nearsightedness), or a positive number (hyperopia, farsightedness). A -1.00 diopter myope is able to see objects at 1 meter clearly. A -2.00 diopter myope is able to see objects at a 1⁄2 meter clearly. The greater the myopia, the strength of the lens in diopters needed to correct the refractive error, and the closer an object must be to be viewed clearly.

Note that 1mm in change to the axial length (front to back distance) of the eye is roughly equal to 3 diopters in power.

— so i'm bug-eyed by 3mm.

Visual acuity is a measure of the ability to resolve fine detail. Snellen visual acuity commonly is used and is expressed as a comparison of the distance at which a given set of letters is correctly read to the distance at which the letters would be read by someone with clinically normal vision. A value of 20/80 indicates an individual reads letters at 20 feet that normally can be read at 80 feet. Normal visual acuity is 20/20.

20/20	Normal vision. Fighter pilot minimum. Required to read the stock quotes in the newspaper, or numbers in the telephone book.
20/40	Able to pass Driver's License Test in all 50 States. Most printed material is at this level.
20/80	Able to read alarm clock at 10 feet. News Headlines are this size.
20/200	Legal blindness. Able to see STOP sign letters.
20/500	"Profound"
20/1000	"Near Total"

— hm... i don't think i can see stop sign letters... so i'm legally blind? do i get special discounts and things?

i give up on finding a conversion formula for diopters to snellen. i refuse to utilize my brain in coming up with one. i didn't like optics class much. go figger. well wait:

In Diopters	20/something
-0.50	20/25 to 20/30
-1.00	20/30 to 20/50
-3.00	20/300
-4.00	20/400
-5.00	20/600
-6.00	20/800

In Diopters	20/someting
0.5	20/25
1.0	20/40
2.0	20/70
3.0	20/100
4.0	20/200

closer... closer...

Nearly 90% of all myopic patients have corrections of less than -6.00 D, which is in the mild to moderate range. The severity of myopia is demonstrated below:

Mild	> –6.00 D
Moderate	–6.00 D to –10.00 D
Severe	–10.00 D to –15.00 D
Extreme	< –15.00 D

AH!!!!

"Divide the result of step 1 (variable A) by 20 to get the starting dioptric power. I.E. 20/50 would result
in a power of 50/20 = 2.5 diopters. I.E.: 20/200 would result in a starting power of 200/20 = 10 diopters."

ARGH!!!

except that doesn't match the above info. I give up! I am unworthy of google!
