Patient's Rx
OD -3.50 +1.25 X 50
OS -4.00 +0.75 X90
2.25 add ST 35
Patient requested that the right eye be Distance and Intermediate Left eye to be Intermediate and near. Anyone know why he would want his rx this way? All I really got out of him was that he has trouble reading in one eye.

Dig deeper with what he means about reading poorly in one eye, and if present with his old eyeglasses. If not, determine what has changed that might be causing the problem. Concentrate on distance power changes, add power, and Rt axis.Originally Posted by TRISH
He may be trying to squeeze the functionality of two pair of eyeglasses (general purpose and task/computer) into one pair. He probably asked his eye doctor to prescribe this way and they refused.
You should not attempt to do this without an Rx from an eye doctor.
Technically, a diopter or so of plus over the distance in one eye might work well for some folks when done on the lenticular plane, somewhat less so on the corneal plane, but rarely acceptable, unless habitual, on the spectacle plane.
Get more specifics, i.e. work distances, heights, etc. and provide a proper solution that is most appropriate for your individual client.

Odd Answer:
The customer is always right . . . eh! Avoid all the hassle and bar room analysis and give him what he wants. As a bonus I'll bet dollars to donuts that a second pair will ensue.

Dick, shame, shame. You can't mess with distance optics. The patient can't self-prescribe monovision. Robert is 100% right: consult the prescriber.
...you only got part of that correct.

I wonder if he, or a friend, is wearing some sore of modified monovision in contact lenses. Maybe this is his attempt to try to copy that in specs. You need to find out what he's trying to accomplish with this before you go further. Then consult the prescriber.
Problem solved!

Mono vision multi-focal ophthalmic system, I have done a few of these. Patient can't make the adjustment from mono vision contacts to a conventional multi focal segmented spectacle lens design. I trial frame the patient but I can do that in WA State as an LDO. Always inform the prescribing Dr as to the patients wishes and what Rx you have come up with as a solution then wait for their response. If it is an outside Rx, I recommend an ice cold beer for the conversation that follows.

I have done monovision with SV lenses. Had a happy camper doing mono va for shooting, using target and scope distances yesterday. Personally I would have a long conversation with the patient about his desire for this set up, and if you can understand the rationale. From there, once I understood what his desired end result was..I would either proceed or confer with prescriber to get the correct rx.

There may have already been some sort of adjustment to that rx--you dont know
You really need to contact the prescriber
Depending on the state, you can get in trouble by even changing the add without talking to prescriber, changing an rx can be considered refracting.
And, sounds like a guaranteed remake with you as the bad guy. If there is no explanation on the RX, the prescriber turfed the problem to you.

I called and asked the patient what he was trying to accomplish with his glasses? He said, "to see".. I'm like,really?Anyway he said he has a condition called xetropy (not sure if I spelled that correctly). He only sees out of one eye at a time and really has no vision in the right eye for reading? I did contact the prescribing doctor. He sent me over another Rx which is:-3.50 +125 X 50
-2.75 +125 X 90 1.25 add ou
hope this works??? thank you all for your input!

Exotropia, probably alternating, and he's usually able to consciously choose which eye to use for different tasks, in this case it the right eye for distance, and the left eye for near.
The second Rx gives your client exactly what he asked for. IMO, fill it for specialized tasks only and not for driving a motorized vehicle, even if it's not stated so on the Rx. Everyone's neck is exposed here; the prudent choice would be to make general purpose eyeglasses by the book (the first Rx), and then experiment with task glasses as needed for desk, home, etc.

What if you were to make a normal distance with add and then a chemistrie clip to "try" and see if the patient likes it,
if not they could have a sunglass chemistrie made and/or a O.U. clip for the working distance.
Just a thought
There are many things in life that catch your eye... but very few things will catch your heart.... Pursue those!
Once had an airline pilot request something like this. He used it to read instrumentation in the cockpit.
Cut add in one eye, but not fudged distance, right? Because I get on the next plane if the latter.

As I remember he had a 8x35 trifocal on the left and exec bifocal on right.
Monovision is a mandated no-no by the FAA. So are BF CLs, IIRC. I made that mistake. Once.
