I have a patient that has come in looking for a new pair of glasses. He is concerned with the thickness of the lens. Thus a 1.74 Essilor will be used.
His script is a -8 with a +1.5 and a PD of 62.
The two frames he has narrowed down to are:
Martin & Martin - Tom (50x16), No ED is spec'd
OGI - 7132 (50x18), ED of 52 is listed
Which of these frames produce a lens that is thinner for this specific patient.
What would the lens thickness be for each respective pair.
