I'll add a couple of other possibilities... the lenses might be photochromic (aka Transitions or 'ChangeLight'). These commonly have a slight residual tint. The older generation of the tech in particular has this mild yellowing.

Or, there might have been a UV block added to the lenses, which also tends to add a low degree of yellowing.

Thanks Paul. I guess it still wouldn't hurt for me to ask the Optician about it.? The lens are Zeiss but I guess that doesn't help. Would the UV block be shown in the prescription.?

Zeiss actually started putting UVProtect in all their clear plastic lenses starting this year I believe. This could be such side effects.

Talk to your optician about it.

Thanks Kame. I just hadn't struck this after many changes of lens over more years than I care to remember. Also, appreciate your previous comments which are most helpful.
