Single vision prescription glasses correct vision at one distance. They help people with nearsightedness or farsightedness. Unlike multifocal lenses, single vision lenses focus on a single distance. These glasses do not address presbyopia, which is the need for vision correction at multiple distances.
Different types of single vision glasses exist, including plastic, polycarbonate, and glass lenses. Plastic lenses are lightweight and impact-resistant, making them suitable for active lifestyles. Polycarbonate lenses offer additional protection from UV rays and are thinner, ideal for strong prescriptions. Glass lenses, while offering superior optical clarity, can be heavier and more prone to shattering.
The key differences between these types lie in weight, durability, and clarity. Patients should consider their lifestyle needs when choosing the appropriate option.
Understanding the benefits and types of single vision prescription glasses lays the groundwork for discussing how to select the right pair for individual needs. Next, we will explore factors to consider when choosing single vision prescription glasses, including lens options, frame styles, and personal preferences.
