Picking the right set of lenses depends both on your lifestyle and prescription. There are several types to choose from, so it’s important to become familiar with the following: single vision, bifocal, trifocal, and progressive lenses. Each offers a different set of corrective features and, in turn, serves a different set of needs.
Single vision lenses provide visual correction for one, fixed distance only. The lens has a single prescription across its entire surface and may correct for myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Presbyopia is a condition in which the eyes have a difficult time focusing on things that are close, such as books, tablets, and smart phones. If you’re presbyopic and wear single-vision lenses that help correct distance vision, they won’t help you when it comes to seeing up close. If you’re not able to see near distances clearly, you may need an additional pair of glasses—or multifocal lenses.
