I have a patient asking me for something and I'm not coming up with a solution that sound good to me so I want to know if anyone has any other solutions
The patient is a 36 year old female who doesn't currently wear glasses, but has a previous subjective refraction (in 2009) of
-0.25 -0.25 x 120
-0.50 -0.25 x 75
New RX
Pl -0.50 x 90
Pl -0.50 x 70
UCVA R: 20/20- L: 20/20
BCVA R: 20/20 L: 20/20 Binoc: 20/15
PD's
D: 30.0 30.0
N: 28.0 28.0
Frame
52-17 with a O.C. height +1 from mechanical center
She complains of eye strain at the end of the day and suffers from dry eye syndrome
She works on a computer for most of the day, however her desk is placed diagonally in her cubicle so that she is her back and the front of her computer display is diagonal to a window as shown in the drawing.
Unfortunately, the easiest solution getting a blind for the window that can be lowered when the sun is causing issues is not an option.
But to make it easier she does not have to be able to look at both her computer and a customer at the same time.
So I have 2 possible solutions that I'm considering, and I'll include my current thoughts on each one.
1. Polarized Gray A with AR (I believe this is only comes in 1.50 Plastic). The polarization will eliminate most of the glare from the excess light, while giving a light enough tint that she can still see when it's not sunny. However, while the monitor is a newer LCD if the display is not set at an axis to allow for use with polarizing filters she won't be able to see her screen.
2. Gradient grey tint with AR (material will either be 1.50, Polycarbonate, or Trivex). While this eliminated the issues associated with polarization I'm not sure how dark to make this tint I'm right now thinking 50->0 but I'm worried that it could either be too dark or too light, if it's an overcast or fully cloudy day 50% is way too dark and I'd be worried about causing next strain from her having to lift her neck to see through the lighter portion of the lens or eye strain from her taking them off on those day. But, at the same time I don't want to make it so light that on full sun days the tint is insufficient.
I'm right now leaning to option 2 because it has less total fail issues then option 1.
So, is there a third option I'm not seeing or has someone used one of my two solutions with success (and if option 2 want kind of tint to you use)
