What is the difference between single-vision and progressive lenses?
Single-vision and progressive lenses serve different purposes depending on your vision needs. Here’s a breakdown of the key differences:
- Single-Vision Lenses:
- Function: Single-vision lenses are designed to correct vision at one specific distance, either near (for reading), intermediate (for computer use), or far (for distance vision). These lenses have the same prescription strength across the entire lens surface.
- Best For: People who need correction for only one type of vision problem, such as nearsightedness, farsightedness, or astigmatism. They are ideal for those who primarily need glasses for a single activity, like reading or driving.
- Characteristics: Single-vision lenses are straightforward and provide clear vision at the distance specified by your prescription. They do not offer correction for multiple distances.
- Progressive Lenses:
- Function: Progressive lenses, also known as multifocal lenses, offer a seamless transition between multiple prescription strengths within a single lens. These lenses correct for near, intermediate, and distance vision without the visible lines found in bifocal or trifocal lenses.
- Best For: People who need vision correction for more than one distance, such as those with presbyopia (age-related difficulty in seeing close objects). Progressive lenses are ideal for individuals who want an all-in-one solution for reading, computer use, and distance vision.
- Characteristics: Progressive lenses provide a smooth, gradual change in prescription strength from the top of the lens (for distance vision) to the bottom (for near vision). This allows you to see clearly at all distances without the need to switch between different pairs of glasses.
Summary:
- Single-Vision Lenses: Correct vision at a single distance, ideal for specific tasks like reading or driving.
- Progressive Lenses: Correct vision at multiple distances (near, intermediate, and far) within one lens, providing a seamless transition for everyday activities.
