It’s Been Over a Year since Your Last Eye Exam
“Once a year is about the amount of time to take your prescription to change if it’s going to,” says Dr. Garg. Eventually, your prescription will become more stable and you can wait two or three years between check-ups, but she recommends most people get an eye exam once a year unless your doctor asks you to come in sooner.
Just remember that all new prescriptions require some time to allow your eyes to adjust.
This is especially true of bifocals and trifocals, which may take several weeks of adjustment.
If your discomfort over and beyond the adjustment period, usually no more than a month, then you need to recheck your prescription.
