To Know Before Coming In:

Eye Exam

PLEASE NOTE: We continue to follow medical office COVID protocol. Please call to let our Front Desk staff know you have arrived before entering our office and wear a mask covering. The health and safety of our patients and staff are a priority. If you are new to our practice, please arrive 15 minutes before your appointment.  Please plan to be at our office for 1 ½ hours and bring the following:

  2. A photo ID.
  3. Please bring a method of payment (check or credit card, no cash accepted) for your copay, if applicable, and any other uncovered services or self-pay charges.
  4. Any eye drop medications and/or over-the-counter drops that you use.  Please bring the actual bottles.
  5. Your Glasses (if applicable).
  6. Contact Lenses (if applicable).  Please wear them to the office.  If you are new to our practice, please also bring the packaging or last contact lens prescription so we can identify the lens(es) you are wearing.

Eric Putnoi, MD
NPI# 1538150487

Missed Appointments

If you need to reschedule your appointment, please make every effort to cancel your visit 24 (business) hours prior to your scheduled appointment or a missed visit charge may be assessed.


As part of a healthy eye examination, we will dilate your eyes with drops in order to thoroughly examine your eyes.  This painless procedure may cause your close up vision to blur and your eyes to be sensitive to light for a few hours following your visit.  You may want to bring sunglasses.  If you have never had your eyes dilated before, you may want to bring a driver. Please feel free to call us if you have any questions about this procedure.
