I have a patient who recently purchased a pair of sunglasses. He is having an issue I can not seem to pin down. He is complaining about yellow lightning streak affect in the OS lens. It sounds like chromatic aberration to me. However, from my limited knowledge I wouldn't expect that to occur when moving from a 1.67 to a trivex I could very well be wrong. I put him in a trivex with the idea that it would play nicer with the wrapped frame than the 1.67. His script follows.
-2.50 -2.25x155
-3.75 -2.00x002
PD along with OC are where they should be. the sun glasses are again, Trivex polarized grey with backside a/R on a 7.25 base in a Ray ban 3498
Also, The lens edges have been blacked out due to the thought process that the thicker edges were allowing an aberration to occur from light entering the edges.
Previously, in his clear pair he was wearing an aspherical 1.67 with A/R on a 0.50 base with a minor script change.
-2.75 -2.25 x155
-4.00-2.00 x 002
His acuities are good, it was only a minor change but the aberration is causing issues for him. Any Ideas? or questions I can clear up?
Thank you all this site a been wonderful and a great help in so many ways.
