Two days ago I went to the optometrist to get new contact lenses. I
have not worn contacts in a while but I left off with the Acuvue
Oasys, which were very bothersome. I don’t think they were fitted to
my eye properly.

So I made a point to my eye doctor that perhaps my eyes just needed to
be fit properly. He agreed and gave me 4 pair of contacts to try.

Pair 1: When I put these in, I had the feeling like I had put them in
a bit wrong. They were mildly annoying, PROBABLY BECAUSE THEY WERE THE
WRONG DIMENSIONS, but my doc chopped this up to "sometimes ya gotta
get used to the lenses and it might take a few days". Now, I am no
genius, but everyone who I have talked to who is happy with their
lenses has said "Yeah, I can’t even feel them or tell they’re there!"
or something close to that. Not once have I encountered someone who
said, "My contacts really bothered me for a week and now I love them."

I couldn’t fall asleep in these for about 30 minutes, ended up putting
in some eye drops and then went to bed.

The right one fell out when I was asleep. Big surprise. Unfortunately
I am not sure the specifications of this lense as I put them in at the
doctor’s place and didn’t keep the thing they come in.

The day after, I put in pair Pair 2.

Pair 2 is Acuvue 2 (my rX is -2 diopters btw) and these were
uncomfortable from the start. VERY. And right after I put them in I
had a meeting to go to go, and it was very painful and I took them out
as soon as I got home. Now, here I am, thinking that I must have
goofed up when I put these in or something, but I look closely at the
3 different kinds of lenses I have, and NOTICE THEY ARE ALL DIFFERENT
DIMENSIONS.

My doctor has given me 4 lenses WITH DIFFERENT CURVATURES to evaluate
and see which one is more comfortable. HMMM, LET ME SEE, PROBABLY IT
WILL BE THE ONE THAT FITS BEST, seeing as they are all silicone
hydrogel lenses suited for continuous wear.

The Acuvue 2′s have a BC of 8.3, and a DIA of 14.0
The CIBA visions, which I have JUST put in, and find quite
comfortable, although not PERFECT, have a BC of 8.6 and a DIA of 14.2
The CIBA night and day’s (the one’s suited for 30 day wear…although
I would never have them in for more than a weak) have a BC of 8.4 and
a DIA of 13.8

So, I guess my question is:
Did my optometrist goof up big here, or do these lenses really come in
such different dimensions that the "personal preference" he was
talking about is actually just the sizes that the lenses come in
(which I find hard to believe…as they would try to fit as  many
types of people as possible)?

Also, do you guys think I should try Bausch and Lomb Purevision? I
have read nothing but great reviews about them.

Thank you very much for your responses!

I am 63 and i am petrified for my future.I have had strabismus in my
left eye that goes out since i was 3. I have had 3 eye surgeries on
the left eye at 6, 16 and 21. Now the eye is back out. I have glaucoma
(using drops),dry macular degeneration and cataracts in both eyes. I
am noticing slight changes. I have been finding for the last 8 months
that I cannot go anywhere that has a lot of space, like a mall or
store, without taking gravol before I go the gravol seems to help me
keep my balance and i use a cane all the time now. I am also noticing
that when I play bingo I am fine if the game is simple like playing
for a line, but if its 2 lines or anything else my eyes don’t seem to
focus on the fact that I have 2 lines covered, the brain or my eyes
don’t seem to register this and I have missed a few bingos. it’s not a
life shattering event, but it cuts into my social activities. I have
only what the doctors call candle vision in the left eye. at the
moment i do see out of the right okay but i am terribly worried about
the future, since if something starts happening to the right eye i
don’t have the left eye to fall back on. when i am tired i get double
vision, and i can no longer play arcade games on the computer because
that activity pulls on the muscles of the left eye. i no longer work
and i stopped driving over 8 years ago. does anybody have any ideas or
is there a medical person who can give me an idea what i am likely
facing. the doctors here don’t tell me much. any input would be
appreciated. thanks.

My dad was asking me about his reading glasses.  His glasses, which
were prescribed about 10 years ago for reading still work great.  He
has no problems reading whatsoever.

His glasses are somewhat big though, or so it seems.  The dimension of
his glasses are roughly 1 3-4"  X   1 1/2".  they SEEM larger than
some of the glasses I see today.

Now.. Is there are reason why some lenses are bigger than others?
And… does the size of the lenses affect the vision in any way?  ie..
visual field etc…

So… To sum up here.  What are the pros and cons of bigger and
smaller type lenses?  Or….  is it purely "cosmetic".

Thanks  LEESA

PS:  My dad is FARSIGHTED with some astigmatism in both eyes.

My 5 year old was recently diagnosed with mild myopia (-.50, -.75 with
cycloplegia) and intermittent exotropia (or exophoria) with 20 prism
diopters and 25 prism diopters, which she seems to have fairly good
control over. She sees 20/25, but favors one eye for distance and the
other for near. Would glasses help is this situation? They weren’t
prescribed because of her age – should we expect her to need them in
the future? I’m a bit concerned that this could develop into something
worse. Also, is it common for a 5 year old to be nearsighted? Should
we expect this to get worse? The autorefraction without dilation was
actually -1.25.

I’ve had these occasionally over the past decade without problem,
sparkling zig zag lines that start somewhere towards  the middle of my
visual field and gradually move to the edges, then disappear.

More recently, over several months, I have a rather different in
nature,  semi-permanant scintillating scotoma, reoccurring every few
days, sometimes staying for hours. It is different in that it is small
and oval shaped, about 3 x the diameter of a letter  ’O’ at normal
viewing distance.  It seems to be getting more persistant.  Should I
be concerned about it? Is there any appropriate treatment/remedy, or
will an opthalmologist tell me to ignore it and hope for the best?

Thanks

Hello

three days ago,  at my work,  i had to install  a free space optic
transceiver for some customer ,  its an infrared laser, around
830-860nm at 16mW power, class 1m, its used to connect two computer
networks between buildings.    Both tranceivers have a telescopes
built in what are used to align both heads to point at each other.
Anyway, i was looking through that telescope  while both tranceivers
where on,  so laser beam was entering my eye through a telescope,  and
an eye contacts , what i was wearing at that time.  I was only looking
through my right eye tho.

Anwyay, the result is that now i feel a pain at the back of my right
eye,  like a needle picking inside my eye,  and my vision is worse
then the left eye.   Also,  that dark dot  (pupil?)  is bigger then in
the left eye.  I thought that maybe it would go away after a little
while but it hasn’t,   now its third day, and the pain doesn’t stop at
all:(   actually its not constant pain , sometimes smaller sometimes
more noticible that i can’t fall asleep.

so i looked it up on wikipedia what does it say about class 1m:

"A Class 1M laser is safe for all conditions of use except when passed
through magnifying optics such as microscopes and telescopes. "

and i was looking through a telescope and an eye contact lens:(   from
further reading i learned that such infrared laser can burn retina in
the eye ball, and cause the sight to be blurry.     What do you
think ,  is my right eye permanently damaged?    can retina
regenerate?   is there any chance that my eye will heal after some
time?  

regards
Tom
