Medical Forum / General / Vision / March 2005Advice on PALS
My perscription is Sphere Cylinder axis -4.75 sph -5.00 -0.75 090 +2.00 +2.00 I have been to Eyemasters - Slim Light Clear Ovations - $320 and Sams - Seiko Proceed II - $235 or Zeiss (not sure what) $240. I work on a PC about 4 hours / day. Any advice would be helpful - thanks > My perscription is > [quoted text clipped - 11 lines] > > Any advice would be helpful - thanks Avoid Eyemasters like the plague. This chain is an organized crime syndicate created to rip-off customers. I have previously documented horror stories with this chain. The Ovations are not is the same class as the "premium" Seiko and Zeiss designs. Seiko Proceed and Proceed II use a very high index lens (1.67) which are probably not necessary for your Rx, although it is a border line case. The higher the index, the thinner and lighter the lens, but optical quality suffers a bit. Seiko Proceed II is a short corridor lens for short frames. That is always a danger sign with PALs, because some lenses are too short for the best vision, especially for the best intermediate vision (working on a computer). It sounds like you may be willing to sacrifice vision for fashion, but be aware of the trade-offs if you go too far. You didn't mention the model or index of Zeiss, but like Seiko they make very good lenses. Unlike the Seiko, Zeiss comes in a variety lens index options for each model. I think a 1.60 index would be fine for you, but avoid polycarbonate (1.59) because of its very poor optical quality. Zeiss also makes some computer lenses called Gradal RD, but these cannot be worn while driving since they only provide near and intermediate vision. >My perscription is > [quoted text clipped - 11 lines] > >Any advice would be helpful - thanks Jeff, If your monitor is about 24" from your eyes, and is at or slightly below eye level, I would usually recommend a separate pair of computer glasses to reduce fatigue and minimize posturing. If you opt out on separate glasses I would probably use a "short corridor lens" to minimize posturing. Make sure that you make these decisions before you and your optician choose a frame. Your optician should have a lot of experience with these difficult to fit lens designs. In addition, It's recommended but not essential that the optician is about your age or older.

My monitor is about 24" away Unless designed just for this specific task, all progressives will require that you tilt your head back for the clearest vision, and then it's only a small area that's clear. If the monitor is large and the text is good size, you might be able to get by without special glasses for another two years. But working half the day in front of a monitor is enough to justify the extra cost and inconvenience of a separate pair of glasses.

My monitor is about 24" away I wear Varilux Panamic 1.60 and they seem work OK for me at a computer terminal. I probably average 8 hours a days looking at a computer screen. My frame height is above average. But my vision is much different than yours (I am farsighted), and there is no single model that works best for everyone. >> How about Varilux Comfort 1.60.

Mark, Borrow or by a +1.25 reader and place it over the your glasses. If your add power is above +1.75 the text should look really nice compared to your regular glasses alone. Just make sure your not tipping your head back when you try this. When I show this to my clients they always seem to tilt their head back like they do at work. We always laugh when this happens because they were not aware that they were subconsciously posturing to make their vision clearer.

I have my eye level at the top of the monitor height (actually a little above the monitor) and am looking down for most work, so I probably don't tilt as much as you think. I agree that computer glasses would be better, but I am OK the single pair. Ok - pretty much decided on the Varilux Comfort. Now have to decide 1.60 or 1.67. Any advise? |
