  1. Types of reading glasses:
    – Single vision reading glasses
    – Bifocal reading glasses
    – Progressive reading glasses
    – Over-the-counter (OTC) reading glasses
    – Custom prescription reading glasses

Reading glasses come in various forms to cater to different vision needs. Each type serves a specific purpose and varies in design and functionality.

  1. Single Vision Reading Glasses: Single vision reading glasses provide a single corrective lens power for near vision tasks. They are designed solely for reading and other close-up activities. Commonly used by individuals who have not experienced severe vision changes, they simplify the process of reading without straining the eyes.

  2. Bifocal Reading Glasses: Bifocal reading glasses feature two distinct optical powers in one lens. The upper portion is for distance vision, while the lower part helps with near vision tasks. This type can benefit individuals who need assistance for both distance and close-up viewing without switching between different pairs of glasses.

  3. Progressive Reading Glasses: Progressive reading glasses offer a gradual change in lens power from the top to the bottom. They allow for clear vision at various distances without visible lines on the lenses. This design helps those who require correction for presbyopia while still needing different powers based on viewing distance.

  4. Over-the-Counter (OTC) Reading Glasses: OTC reading glasses are commercially available and do not require a prescription. They typically come in various magnification strengths and are suitable for occasional tasks like reading. While convenient, they may not provide the precise correction needed for individuals with specific vision problems.

  5. Custom Prescription Reading Glasses: Custom prescription reading glasses are tailored to an individual’s specific vision needs based on an eye examination. An optometrist provides the correct lens power and ensures that the glasses fit well and offer optimal comfort.
