VOSH Illinois first made glasses in the field in 2013 on a trip to Samapaita, Bolivia.
They made approximately 300 pairs of custom glasses in the field.
The lab encompassed 5 individuals.
One person pulled the lenses and marked them with a lensometer.
The second person centered the lenses for the patient’s PD and traced the frame shape onto the lens.
Third person used a belt sander with either 60 or 80 grit to grind the excess lens material down to within a couple of mm of the final size.
The fourth and fifth persons were both using a hand edger to take the lenses down to final size and mount them into the frame.
The glasses were then cleaned and dried before being dispensed.
The patients saw much better than they did with used recycled glasses.
The Rx range ran from +6.00 to -6.00 in spheres and also with -1.00 cylinders.
Far more plus lenses were used than minus.
On next trip they plan to take both -1.00 and -2.00 cylinders from +0.50 to +4.00
Please contact Dr. James Vaught for more information:
Suggestion is to transport in pelican cases:
One pelican case for the belt sander and lensometer.
One pelican case for the two hand edgers.
One pelican case for the frames and lab trays.
1. Belt sander: You will need 8 belts for each trip. They are a dollar or so each.
