Changing designs based on use case

Hi everyone, first time poster here.

We have a PAL wearer who splits his time between outdoors (driving, visiting construction sites, etc) and indoors (on PC looking at spreadsheets, etc) quite evenly throughout his working day.

Would it be ideal to keep him in the same lens design for both indoor PALs (clear with AR and blue control) and outdoor PALs (polarised)?

I'm thinking of splitting them up with the Hoya Lifestyle 3 Indoor and Outsdoor designs, respectively. Will this mess with his optics and introduce adaptation problems? For context, his a pre-existing PAL wearer and has the Rx

OD +2.25/-1.25x99
OS +1.50/-0.75x91
A +2.25

Many thanks!

Sounds like mid/near is the most used part of lens indoors. I would suggest Office Readers, or similar as a third pair occupational.
As for general use indoor and outdoor, sticking with the same design is what I would recommend for a first timer.
Outdoor designs generally provide a very wide DV, but at the expense of NV. Indoor designs generally provide more NV/Mid at the expense of DV periphery. Every design is different.

Case in point. I wear the Zeiss ID2i and the IOTAlpha 45, both fully compensated. The IOT has a wider DV, the Zeiss has a wider Int., both can be worn for short periods of time comfortably while I work on my laptop. After an hour or so, I always put them down and use my 4M Office Readers.

Why? What problems is he having? You can not improve on an asymptomatic patient/customer. It is usually best to let sleeping dogs lie. Unless there are some pecuniary interest involved in the decision.

I am a strong advocate of computer glasses. So are my patients :)

If the outdoor pair is polar sun (very nice),
and the indoor pair is a computer pair (very nice),
what's he going to use for his general purpose dress Rx? The previous pair?


If he doesn't want to use his old pair, then I think you have to use a general purpose PAL indoors, once again, instead of the computer pair.
Alternatively, you could make a nice computer pair and make his general-purpose PALs photochromic, or even now polarized photochromic (<---no experience with these, yet, sorry).

I would say a Chemistrie clip would be better than photochromatic for driving and visiting construction sites. A lot of different lighting conditions, in and out of buildings, most likely on a hurried schedule. Don't want to have to wait for lenses to clear up before they can look at schematics, instruments, etc when coming indoors. Also they are polarized, on and off in a second with one hand.

In retro-smell, this is probably a consumer post.

Hi Drk. I don't know if there is a way to deny or confirm to you but certainly not a consumer and will be contributing to the forum where I think I'm worthy of contribution.

Ok, you smell like an optician, now. Salty! Keep on.

I usually only recommend a different design for suns for one of two reasons:

Reason one: they don't want to splurge on their suns- in which I like going with SV or potentially Flat-Tops opposed to downgrading PAL

Reason two: active outdoor lifestyle/ wrap sport frame- in which case, it is nice to have a lens designed for such application.

I agree polar clip-ons are a better option than Transition (polar or not).
