Here is my story, my problem, and my description of my walk on the far(sighted) side.
I have been unsuccessful in replacing a former co-worker’s lens. For simplicity’s sake, we will say the prescription is +6.00 O.U. She is a 45 year old female that wears RGP contacts most of the time. She can successfully wear her Spectralite single vision lens made in 2005, but we both know a need for a progressive lens is eminent.
The problem is, I have not found an acceptable replacement for her Spectralite lens. If I cannot find single vision lens that works, how will I recommend a future progressive that works. I have made aspheric 1.67 lens, aspheric 1.60 lens, spherical Trivex, and digital 1.60 lens. With every lens she has described the peripheral vision as “warpy and wavy”. Had this been reported with only one set of lens I would have dismissed it as poor surfacing. Her old lens front surface measures +7.00. The new lens measure from +6.00 to +6.50.
Today I tried to “walk on the far(sighted) side”. I inserted 2 high minus soft contact lens that left me with an over refraction of +6.00. I then put on her glasses with the digital lens and the Trivex spherical lens. I immediately became sympathetic for all the high power hyperopes I have been fitting for over almost 40 years. The room movement with head movement was obvious. What I found informative was observing the “bending of walls” with both sets of lens. The digital lens did less “bending”, but it was still pronounced. It is my opinion, this “bending” is the problem my former co-worker has with the glasses. I did not observe any optical defects in either pair. I have not had the opportunity to wear her Spectralite lens.
So my question is:
What is the best replacement for the Spectralite lens?
