Engineer with extensive ophthalmic mathematics background feels his problems is from the 3rd order aberration coma. Is he right?
Previous rx: R+4.00-.25x83 Left +4.50 sph add +2.00
New rx: +4.50sph OU Add +2.00
FT28 CR39 (insisted do to better optics) Avance AR +8.25 bc.
Autoflex 10 57 16 b47 ed65 (same as previous frame - yes it's way too big) PD R32.5/31 L35/33
Old seg height 16.5 new 21.5
OC set 30 from base of frame ou.
Center thick old @5 new 7.5mm.
As everything is virtually the same am I correct to say that he can't have both a higher seg height and the same thickness?
He feels off axis/peripheral vision has a halo around images/words.
Is this what a coma issue would present?
Thanks in advance for any thoughts/suggestions.
