The Near Vision Handbook — Digital Guide

A 17-page guide to what changes in near vision after 45 — and how to work with it.

Almost nobody is ever handed the arithmetic behind the reaching. This handbook lays it out plainly, in two numbers, and then covers the practical side: why the drawer fills up with readers, why a stronger pair can feel worse, how to pick a starting strength by age range, what the first two weeks actually feel like, and the free changes to light and distance that make close work cost you less.

What's inside

• The arithmetic nobody hands you — the two numbers that explain the last five years
• Why your arms became the workaround, and the exact point it stops working
• Six symptoms that look unrelated and share one cause
• Why single-strength readers multiply around the house
• Why prescription progressives end up unworn — honestly explained
• Choosing a starting strength by age range, plus a ten-second test you can run now
• The first two weeks, day by day
• Lighting, distance and screen settings that reduce the load for free
• Night driving after fifty
• When it is not presbyopia — the signs that mean book an appointment
• Appendix: the full age table and a plain-English glossary

Delivered as a PDF you can read on a phone, tablet or computer, or print.

This guide is general information about an ordinary age-related change in near focus. It is not medical advice, it does not diagnose anything, and it is not a substitute for an eye examination.
