Glasses are the traditional way to correct refractive error (nearsightedness, farsightedness, and astigmatism) and presbyopia. Technological advances have made eyeglass frames and lenses better than ever. Frames are lighter and more durable, lenses are thinner and lighter, and new lens coatings make it possible to choose lenses that are more scratch-resistant, quickly change color in different lighting conditions, and are free from distracting reflections.

Nevertheless, remember that whenever you have a new pair of eyeglasses, it may take some time to get used to them. This is especially true if you have a change in your astigmatism. Stronger lenses for astigmatism correction may make objects look slightly distorted at first, or give you an undesired sensation of movement. These temporary sensations can also occur with your first pair of progressive lenses to correct presbyopia, or an increase in the power of your progressive lens prescription.

Your eyes will adjust more quickly to any prescription change or change in lens design if you wear your new eyeglasses all the time, instead of taking them on and off, or switching back and forth between your old and new eyeglasses. If you still have problems after a week or so of wearing your new glasses full-time, return to your eye doctor or optician for a recheck of your prescription and your new glasses.
