Ophthalmology & Optometry/glasses



How often should glasses be replaced or changed? For my contacts I wear ACUVUE Oasys with hydraclear plus, and my prescription is -12.0 left eye and -11.50 (bc 8.4 dia 14.0 if that matters). I always wear glasses or contacts. I change my contacts every two weeks, but I have not been getting new glasses. My old eye doctor moved to a different state, and she always told me when to get new glasses. My new eye doctor never says anything about getting new glasses. My eyes are very healthy for as bad as my eyesight is. I wear my contacts 95 percent of the time, but occasionally allergies force me to wear my glasses. I have not bought new glasses since 2011. My vision is able to be corrected to 20/20 with contacts and glasses. I am just wondering if it is time I need to buy new glasses or if my old glasses are fine.

Hi Annie,
The two factors I can think of are your glasses prescription and the condition of your glasses.
Most of my patients with higher Rx's usually only where their glasses for short amounts of time in the morning or evening.  They rarely, if ever, leave the house with them. In these cases very small prescription changes in the glasses are not a concern. If your contact lens prescription has not changed; and your glasses are still in good shape, they are most likely ok.  If your contact lens prescription has changed since you purchased the glasses,  you may need a new set to obtain the best vision.
Any doctor's office can get readings off your old glasses which will give the approximate prescription.  They can then compare the reading with the current glasses Rx.
I hope this helps,
Dr. Wojciak

I am an Optometrist with 25 yrs experience. I currently practice in Rolling Meadows, 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.
