Astigmatisms commonly change over the course of your life. This can be caused through the natural vision degradation that occurs with aging as well as from your eye continuing to change shape. If you notice your vision getting worse even with your corrective lenses, it may be time for another exam at Brookleigh. In some instances, your astigmatism can actually decrease and improve your vision slightly, but either way, you will need new glasses or contacts to fix the astigmatism in Brookhaven.
