FAQ
Eyeglasses and contact lenses are common, and there is a broad spectrum of prescriptions, coatings, and lens types available to support various vision correction needs. Different types of magnifiers are also available to support reading and close-up tasks.
Eyeglasses use lenses to bend light and focus it onto the retina more effectively than the natural lenses in your eyes are able to. An optometrist adjusts the eyeglasses to bend the light just enough to account for the incorrect shape of your natural lenses.
Contact lenses are safe if you keep them clean between uses, avoid overuse, regularly replace them, and avoid sleeping in them. Have an eye exam at least once a year to ensure that you’re taking care of your contacts correctly.
Over-the-counter eye drops can help keep your eyes moist, soften the skin around the eyes, treat inflammation and redness, and rinse your eyes. Prescription drops can manage allergies, kill bacteria, numb the eyes, dilate pupils for eye exams, and promote healing.
Consult an eye care professional for guidance, diagnosis, and measurement of prescription products, as well as for recommendations about which over-the-counter products may best support your eyesight problems.
