Computer glasses?
|
|
|
Have just had my second cataract removed (first was a month ago.) Seem
to be working just fine, but I'm just ine the first week. I'm now
waiting about 3 months to get a new prescription. In the meantime the
doc says to get some "drug store" glasses for reading. I've had some
for a while and they work fine. Now I need something with a proper
focal length for computer use.
Searching the internet, I'm not sure that what I find will do the job.
Does anyone have a source for cheap glasses for that purpose?
BTW - I'm seriously considering trifocals later. I've been using them
successfully for many years, |

Dear Jim,
I am not certain what you are looking for.
You can find simple spherical plus
lenses on the rack. Just put them
on and read at a comfortable
distance. They are low cost -- about
$10, so you can try several for
comfort.
If that does not work, a convenient
source of $19 is on this link.
Bifocals are more expensive of course.

Good luch with you catarack operation.
Best,
Otis |

First, there have to a few assumptions: that you have little or no
correctable astigmatism and that both eyes require the same distance
correction (or if your doctor got the IOL power right on, no distance
correction.)
That being the case, the next factor is the distance from your eyes to
the computer monitor. For a 22-26"/55-66cm working distance, a + 1.50
or +1.75 lens should be about right. A little closer, a little higher
power, further, a bit less.
If the criteria in the first paragraph are not met, then you are better
off having your refractive status/prescription checked and ordering the
correct spectacles. Measure your working distance and have the doctor
customize your lenses for you.
Pre-made inexpensive readers can be purchased at drug and discount
stores, from local optical stores and some eye doctors. They assume that
your eyes require the identical powers for correction and that your eyes
are spaced equally at around 62mm. Errors around all those criteria may
make a less than adequate cheap fix.

Sorry, guess I'm not being clear.
-Reading glasses don't work well for computer work. You need a
different focal length, or you have to get closer!
-I'm looking for a temporary solution until I can get a permanent
prescription. |

Computer glasses are just weaker "reading" glasses (the weaker you go,
the farther out the clear point of focus). If +2.00 readers work well at
17", then +1.00 or +1.25 readers should work well at 24". Having said
that, if you want a more accurate Rx, have an o.d. refract you and make
up a custom pair that will be right on. If you had small incision,
stitchless procedures, they may not even need changing in 2 or 3 mos.
If you had any stitches, then you probably will have to have them
changed in a few weeks/mos. I had the former 4 mos ago and my Rx has
been pretty rock solid unchanged since day 2 post-op.

Bill,
Most of the post-op Rxs that I fill are from two to four weeks after the
surgery. I have a three month "Rx change warranty" just in case, but it has
been a long time (years) since this has been an issue. I tell my clients to tell
their doctor (unless there are complications) to Rx at two weeks to get the
client "up and running". In some cases when the client is younger or left with a
large Rx change and/or anisometropia I'll try to get an Rx at one week and make
a temporary lens in the old glasses and then make new glasses at the three month
follow-up.

Jim,
Trifocals are ok for general use but not as comfortable and functional as
specially made glasses for use in front of a monitor, sheet music, or other
tasks at 20" to 28". If all you need to do is check your mail and write a few
short letters then regular street glasses should be tolerable, especially if
your neck is flexible and you have a good size and quality screen. Otherwise,
computer glasses will eliminate posturing, increase acuity, and decrease
fatigue.
Hope this helps

What I did, since I knew I was going back to work 3 days after both
surgeries, is I took a recent pair of bifocals I had, popped both lenses
out and had plano with a 2.25 add put into them, same style, same seg
ht. Then I swapped the old right lens for the new right and took these
with me to the 1st surgery (as it was my left eye to be done first).
Got up off the table and wore those just fine (could have used some
slab-off, but I prism adapt pretty quickly) until the following week,
when I popped the other new (right) lens into the frame just before
surgery, jumped off the gurney with the new ones, and wore them until I
could tell I wasn't going to change much more, about 3 more days, and
made myself a pair of progressives that still work today, 4 mos later.
Never missed a day of work. Piece of cake. Nobody should put off this
procedure. First sign of trouble, have it done, and if you're a
moderate to high hyperope and presbyopic, don't even bother to wait for
trouble...

I cannot overemphasize my satisfaction with the 99¢ store or a swap meet
where I bought several in different strenghts at about a dollar each. I am
using such a pair at my computer now.

It is true that it may be difficult to get the correct focal length if you
do not have occular implants. What I do is to just wear reading glasses over
my street glasses. You can call me six-eyes. If you require differing
strengths for the two eyes, just buy two pair of a type using the same
frame. Cheap enough. Right now I am using a pair marked +1.50. I leave the
tag on.
At the swap meet, I attend, I can also get higher power glasses often used
by older machinists.I have a pair with a number of plastic flippers of
various power. Those cost more and are probably not necessary.

Different strokes. Fortunately for my business, most of my patients
wouldn't be caught dead using such contraptions (I guess northern
Californians can be a bit uppity). Or maybe we're just not quite so
resourceful. I especially like the bit about leaving the tag on. You
know you could probably talk an o.d. or optician out of an old 6 or 10
piece frame display that you could set up right there in your shop so
your entire collection could be at your fingertips.

Bill,
Compared to what? They are certainly better than no glasses at all. My clients
tell me that coated Rx multifocal lenses are vastly superior in all respects
(except cost-about $200 with frame). If all you use them for is looking up a
phone number or reading a menu in the restaurant then go cheap and save a few
bucks. If your at a desk eight hours a day or if you are an avid reader you will
wonder why you didn't upgrade to quality optics heretofore.

I get a kick out of those people who go out and spend hundreds and
hundreds of dollars on a new lens for their camera, that they might use
a few time a year, and then head over to the thrift shop for
reading/computer glasses that they use for hours every single day.

It's a good thing most swap meets don't have contact lens hawkers...
