Hi folks got another curly one for you all to think about. pt comes and see's me Rx of, hasnt worn glasses in 20 years as finds vision better without. R:-0.75/-3.50x53 L:-0.75/-3.75x143 wearing Hoya GP Wide PD: 31.0/31.5 Height 18mm complaining at blurred vision in distance and reading checked the Rx client complained that rx blurred and worse than specs but was the same rx? specs better and can get them into focus by adjusting her head to the left around 8 degrees, both rx's the same in specs and trial frame. will double check rx again see if there is some changes that need to be made. however when wearing the specs she can get them into focus so dotted the lenses where the pupils sitting getting a different PD and height (PD 34.5/32 height 20mm) decided to get the pt to take a walk around the shop and then make her way back to me to double check these measurements got different again (PD 27.5/29.5) Checked on a pupilometer and different again (PD 32.5/31.0) which PD should i be using and how can i get a stable PD not changing every 5 minutes, and what would explain the Rx in trial frame being blurred but Rx in specs clearer.. going to raise the height to 20 as this will suit the lens better but still unsure on PD and Rx outcome.
