The solution for breaking in new eyeglasses is right before your eyes: The best way to get used to a new pair of glasses or prescription is to wear the new eye wear as much as possible. However, a few exceptions apply. Certain types of prescriptions are meant to be worn only as needed. New eyeglass frames frequently require adjustments after you have worn them for a few days or weeks. Take your glasses back to your eye care practitioner if your frame is uncomfortable or you cannot adapt to your new prescription after a few weeks.
Check the fit of your glasses. They should feel comfortable and perhaps a tiny bit snug at first. This is because new glasses stretch a little as you wear them and take them on and off. Your glasses should rest comfortably on your nose and feel good behind your ears but not feel too tight.
Wear your new glasses as much as possible and as prescribed by your eye doctor so you'll adapt quickly to your new prescription. Your optometrist or ophthalmologist specifies on your prescription how you should wear your new glasses -- whether for reading only, near vision or distance only. Progressive lenses, also called no-line bifocals, take a little longer to get used to.Your eye care practitioner should teach you how to use the lenses and explain the adjustment period.
Wearing your old glasses is a no-no. Going back and forth between an older prescription makes adjusting to your new glasses more difficult.
Take your glasses back to your optician or optometrist's office if you are unable to get used to your new glasses after a week or two. The optician can check your frames to make sure they are adjusted properly and will verify that your lenses were made according to your prescription. If the lenses are right and your frames fit, schedule an appointment with your eye doctor to discuss the prescription.
Most lens manufacturers and optical retail stores exchange lenses within a specified trial period if you are not able to adjust to the lenses. Check with your eye care practitioner to find out his or her policy on lens exchanges before ordering your glasses.
