Different people react differently to a change in prescription, ie. new spectacles. It is normal for new specs to be a bit uncomfortable for a few days, especially when there has been a change in lens design (eg. moving from single vision to multifocal lenses) or a significant change in prescription (eg. eye got worse or better than before). The discomfort may include a feeling of pulling, disorientation and sometimes headaches. These symptoms should go away after a week or two. It is important to report these symptoms to the optometrist so you can get the necessary reassurance or to sort out any problems there might be with the lenses. Don’t suffer in silence.
