Has your glasses prescription expired? Update it from home with your iPhone and laptop—you’ll use both to display the vision tests. Prescription Check is Warby Parker’s telehealth service (read: app!) that, if you are eligible, allows an eye doctor to assess how you’re seeing through your glasses and provide an updated glasses prescription. Download the app, take a few vision tests, and answer a few easy questions to determine your eligibility. If the doctor issues you a prescription, you will be charged $40. (You won’t be charged if the doctor recommends that you get a comprehensive eye exam.) Quick note: Prescription Check is not a comprehensive eye exam and it isn’t meant to replace visits to your eye doctor. It’s important to get your eye health examined periodically, even if you aren’t experiencing any vision problems, so please follow the advice of your doctor. Good to keep those peepers in check.
