Readers (also known as reading glasses) are eyeglasses specifically designed to help people see up close, particularly for tasks like reading, sewing, or other activities that require near vision. They are typically worn by individuals who experience the inability to focus on close objects.
Key Features of Readers:
-
Magnification Lenses: Readers have lenses with built-in magnification to help you see small text or detailed objects clearly at a close distance. The magnification strength is typically denoted in diopters (D), with common strengths ranging from +1.00 to +3.00
-
No Prescription Needed (for Non-Prescription Readers): Many readers are sold over-the-counter, meaning they don’t require a prescription from an eye doctor. You can buy them in various magnification strengths to suit your vision needs. However, if you have specific eye health issues or need correction for both near and far vision (like with bifocals or progressive lenses), a prescription may still be necessary.
-
Single-Vision Lenses: Readers generally only offer correction for near vision, making them ideal for activities like reading a book, working on a computer, or doing crafts. They are not designed to correct distance vision or to be worn all day like prescription eyeglasses.
When Are Readers Used?
- Reading Small Print: If you have trouble reading small text on books, newspapers, or labels, readers can provide the magnification needed to make the text clear.
- Working on Screens: People who experience eye strain or discomfort while working at a computer, especially when performing detailed tasks like writing or editing, may use readers to reduce strain.
- Close-Up Tasks: For activities like knitting, crafting, or sewing, readers can help you see fine details more clearly.
