Ugh...I'm getting glasses.

[MJinZ]

I've had glasses since I was 8 and just recently tried contacts. The first brand was blurry. The second brand felt like there was acid in my eyes for the 3 weeks I wore them. The third brand was impossible to get in. I'm about to try a 4th brand, but I don't have high hopes.

Glasses do have quite a bit of distortion on the edges, but straight-on they are definitely better than contacts (especially at really strong prescriptions like mine). Plus, if you're near-sided, my near vision with glasses is much better than contacts. When you look underneath the glasses the near vision is even better.

With distortion, though, you get used to just about anything. Your brain is extremely good at adapting.

I'll probably get laser surgery. Even if I get to 20/40 I'll be ecstatic (I'm about 20/900 now).

Only thing worth using is Acuvue Oasys. I've tried them all.

I tried contacts once when I was a kid. Optometrist suggested reading glasses even though I could see just fine.
HOLY FUCK! How do people stand to put those pieces of glass in their eyes?

Mind you, this was about 1967...and contact technology was still fairly young. The contacts were hard bits of glass...not the thin flexible ones used today, but still...an eyelash in the eye just about drives me nuts...I can't imagine voluntarily putting something IN my eye like contacts.

Yeh and they operated computers with punch cards then too. Welcome to 2010.

So you are an old fart after-all :sneaky:..... there should be a forum rule about misleading avatars. ^_^

Contacts are made out of a silicone polymers with water these days... which is still, a bit like putting glass in your eye from the common element Si (silicon) present.

heh-heh...I remember when punch-card operator was considered to be a GOOD job...
We took a tour of one of the local "data entry" businesses when I was in the 7th grade...got to see "THE COMPUTER" in the back room...filled a room about 20' x 20'.

Polarized lenses have a special process applied to them that blocks out lightwaves from particular angles and greatly helps in reducing glare.

Your heart is in the right place

It's not a coating or a process, the "polarizer" is a bona-fide filter.

http://en.wikipedia.org/wiki/Polarizer

Polarized lenses (as in those on (some) sunglasses prescription and non, camera lenses, some windows, etc - only let light it that is "polarized" in a certain drection. IT basically lets you see through the surface of water, through windows and cuts down non-metallic glare.

My dad does Biomedical engineering and EE for hospitals. He fixes CAT/MRI/radiology/cath lab, etc. When I was a little kid, maybe 6 he showed me the new "portable" CAT scan housed in a double-wide trailer. The gantry and maybe the control room was the only part the patient ever saw. The rest of the double-wide was "the computer". Which was froze-toes 50 degrees, 3 long rows of reel-to-reel tapes, rackmount disks, processors, image processors, memory units, display processors, etc.

It was straight out of wargames.

These days, all that equipment is replaced by a Mini-ITX sized PC in the control room.

Am no optometrist, let alone yours, but the vision most achieve with hard (that is RGP or Rigid Gas Permeable) or specialty lenses is typically better than glasses.

There is a certain "learning curve" with RGP's though. It really sucks having hard bits of plasticy stuff in your eye for a couple weeks till you learn. There is no toric funny business, just crisp, sharp vision for people with bad bad astigmatism.

Good thing you aren't an optometrist, since you obviously don't know what "toric" means.

Unlike a spherical lens, where the curvature(and vision correction) is the same, no matter which way the lens turns, a toric lens has a non-uniform curvature. Toric lenses are available in both soft and RGP.

To correct for astigmatism, you must have toric lenses. And with toric lenses, they have to stay in your eye in a particular orientation. In other words, if the lens is in the right place, your vision should be clear, but if you rotate the lens, it will get blurry.

Toric lenses are designed to stay in the correct orientation, but all of the lenses I tried would sometimes rotate out of position and it was annoying having to blink a whole bunch to get them to rotate back into the right place.

Actually, it does feel a bit like having an eyelash in your eye at first. And it is quite annoying for the first couple of days. That's why when you are first starting out, they suggest you only use them for a couple hours a day.
But by the end of a week, you barely notice them.

Of course it's a process. Do you even know what "process" means?

Polarized lenses go through a manufacturing process that filters light that is polarized in a particular direction.

I was apprehensive about getting glasses three years ago. Three years on I'm used to them and personally I like them, although it usually takes me months to find a pair of glasses I like.

I'm booked in with an opticians this Saturday to have an eye test and get new glasses. It has taken me 4 months and 11 opticians later to find a pair of glasses that I like. I'll be buying two identical pairs.

btw I wear my glasses nearly all the time and my eyesight has deteriorated further (I'm long sighted), which is likely due to me staring at a computer screen for 10+ hours most days (even though I take regular breaks).

Edit: I'll never wear contacts because I don't like the idea of having to put something directly on my eye.
