When you put on a new pair of glasses for the first time, you may expect to see everything perfectly, but for many people there is a period of adjustment to new glasses. This can be compared to wearing new shoes which may take a little time before they feel comfortable. Because our brains interpret what our eyes see, it often takes a while for the eyes and the brain to coordinate getting used to a new prescription.


The symptoms of wearing new glasses vary, and it is possible that you may have no problems at all. At first your vision may be a little blurred and your eyes may feel tired quickly. You may need to read at a different distance than before, and you may experience headaches.

Time frame

The length of time for adjustment depends on a number of factors, such as the strength of the prescription, a change in the prescription, whether you are wearing glasses for the first time, if you have changed the size of your frame, or if you have changed from contact lenses to glasses. Even if your prescription hasn’t changed, you may need to adjust to a new lens type.

It is usually easier to get used to single-vision (unifocal) lenses, and this should take about a week, whereas adjusting to multifocal, bifocal or special glasses can take several weeks longer. If you have glasses for the first time, the best way to get used to them is to wear them as often as possible and as directed by your optometrist. If you have had a change in prescription and the difference is significant, the adjustment period may be 2 weeks, or even a little longer.


The first step is to ensure that your glasses are fitting correctly. If your frame is not level on your face, or tends to slip down your nose, your prescription may be affected. Get your optometrist to check the fit and adjust if necessary.

If you have worn your new glasses for at least 2 weeks and you are still experiencing difficulty adjusting to the new correction, your optometrist may recheck the lenses to be sure that they have been made according to the prescription. If the lenses are correct, he may recheck your eyes to see if the prescription needs to be adjusted. Remember that you cannot get used to new glasses unless you wear them. Wearing your old prescription while trying to get used to a new one will make the adjustment period take longer.
