It can sometimes take a bit of time to fully adapt to a new prescription and this is totally normal. Make sure to give your eyes the best chance to adapt to your new glasses by persevering with the new prescription. Try to wear your new glasses full time for at least 7 days for single vision, and 14 days for multifocal lenses without swapping back to an old pair.
If you are having ongoing issues with your new glasses, the best thing to do is to take your glasses to one of our showrooms so that our knowledgeable and talented staff can adjust and fit your glasses for you. Make sure to book an Aftercare Slot. If you aren't local to one of our showrooms, contact our customer experience team and we can help you remotely. We would never see a customer stuck with glasses they aren't getting on with.
