AboutMichael J. Wojciak, O.D. Expertise I am an Optometrist with 21 yrs experience.
I currently practice primary eye care in Lombard & Schaumburg,
Illinois. I specialize in all types of contact lenses.
Please forward appropriate questions pertaining to eye exams, glasses or contact lenses only. I will always attempt to be as "specific" as I can on my answers. This is often difficult when the questions do not provide enough information or visual presentation is needed.
***I will reject any question involving self-prescribing of contact lenses or involving contact lens measurements/comparisons (such as changing base curves, measurement comparisons between brands etc). Contact lenses are a medical device and need to be properly fit by your Doctor. Also in respect for patient privacy, I will not answer third party questions, unless a parent or guardian is asking a question about their child.***
I appreciate your confidence.

Question I have a prescription with a PD of 57 and a +1.50 SPH in both eyes. I want to buy a pair of Oakley Sunglasses. But, when I went to order a pair online, I can only get a +1.50 SPH with a PD 60 but not a 57. Would this be a problem?
Answer Hi Jeff,
"PD" stands for pupillary distance or the distance in millimeters between the eyes. Gross errors in this measurement in very high Rx's will cause eyestrain and possibly some blur. A difference of 3mm however in your low power should not cause any issues. Also, most pd related issues occur when doing prolonged computer work or near work, which I doubt you will be doing in your Oakley sunglasses. You should be fine.
I hope this helps,
Dr. Wojciak
