Primer for First Timers
The information provided below is intended for educational purposes. It should not be considered a substitute for a professional eye examination.
Presbyopia makes it difficult for people around age 40 to read clearly or do close work. This natural aging condition is not a disease; it occurs as the lens in the eye begins to lose some of the elasticity needed to focus on near objects.
- The need to hold reading materials farther away to focus.
- Headaches or tired eyes after close-up work.
- Blurred vision at normal reading distance.
- More light required to see clearly.
- Cornea: a clear covering over the front of the eye.
- Iris: the colored part of the eye surrounding the pupil.
- Pupil: the black hole in the middle of the iris.
- Lens: the part of the eye that allows you to focus.
- Retina: a thin layer of nerves on the back of the eye that detects light.
- Optic Nerve: a bundle of nerves going from the eye to the brain.
- Single Vision Full Readers
- Full frames provide uniform magnification over the entire lens.

- Single Vision Half Readers
- Half frames allow you to glance over the top of the frame for clear distance vision.

- The upper portion of the lenses are clear. Lowering your eyes to the bifocal segment provides magnification for reading.

- Progressive No-Line Bifocals
- The upper portions of the lenses are clear (not magnified). As you lower your eyes, the magnification increases gradually, allowing you to see better at different close-up distances.

- Sun Readers
- The tinted upper portion of the lenses are clear (not magnified). Lowering your eyes to the bifocal segment provides magnification for reading. The entire lens offers UV protection.

- Computer Style Progressive
Computer lenses are a specialty type of progressive lens designed for today’s world. Like any progressive lens, they eliminate the need for multiple pairs of glasses. More importantly, they give your eyes the focal length they need as they need it, greatly reducing eye strain.
Computer lenses, sometimes referred to as “office” or “occupational lenses,” make it easy for your eyes to move back and forth between near-vision computer work and mid-range printed material.
1. Select your normal reading magnification power and the lens will do the rest. The middle portion of these lenses allow for intermediate range viewing, perfect for looking at the computer screen as well as other tasks like cooking, following sheet music, drafting, and more.
2. As you lower your focus to the bottom portion of the lens, the lens acts like any reading lens, making it easy to read cellphone screens, pill bottles, newspapers, or the latest best sellers. The included high-quality, anti-reflective coating reduces eye strain even more, allowing you to enjoy your work and hobbies.
