I want lenses that include allowances for different centers of rotation if possible. Reason: My opthalmologist (now retired) added a prism to my prescription awhile back but in a later exam discovered I did not need it. My theory is that mistake "may have" been caused by a difference in the center of rotation of my eyes. Of course I don't know that, but when I got the Physio lenses I now have (about 6 years ago) they were the first lenses I've ever had (I'm 68 and started wearing progressives in my 40's) where both eyes were in perfect focus. With previous lenses to achieve perfect focus I'd have to shut one eye and move to the spot of perfect focus and then repeat with the opposite eye and it was a differenet spot for each eye for near vision like a computer monitor which I use about 8 hours a day.
My current prescription is:
Distance:
Right: + 3.25 Sphere, - 1.5 Cylinder, 090 axis
Left: +4.00 Sphere, -.50 Cylinder, 095 axis
Near:
R and L: +2.25
This prescription hasn't changed much in the past 6 years but when i saw the "eye code" technology on the Essilor website I immediately wanted it (probably because I am an engineer) and I've waited thinking it would be avaialbel but not even practices with the Visioffice system in Columbia, SC are offering any eye-code lenses or S-4D. The closest is Greenville, SC about 100 miles away and not very convenient. Are "eye code" lenses still available? Like a Physio 360 "eye code" lens? Or does the S-4D include replace them and use the eye code data and employ adjustments for center of rotation, etc?
Clearly I am confused and need advice and hope one of you experts will be kind enough to guide me. A private message is fine if this isn't something you feel should be on the optiboard.
Thanks in advance,
Nick
