Near Vision Test (Educational)

Near vision is the ability to resolve detail at reading or phone distances — often around 40 cm / 16 inches, though people hold materials at many distances. Presbyopia and uncorrected refractive error are common reasons near tasks feel harder with age or after long visual work.

This educational near chart helps you notice how text size and distance interact. It is not a clinical near-acuity measurement and does not prescribe reading glasses.

Follow these educational steps:

1. Hold your device or sit so the chart is at a comfortable reading distance you actually use for books or phones.
2. Use good, even lighting that does not create glare on the screen.
3. Wear any reading glasses or progressive lenses you normally use for near work if you want to explore your usual setup.
4. Cover one eye at a time and note the smallest text you can read without straining.
5. Compare comfort at your habitual distance versus a slightly farther or closer distance.

Being able to read smaller text more comfortably at your chosen distance suggests better near resolution under those conditions. Difficulty that improves when you move material farther away is a pattern people often notice with age-related near focusing changes — but patterns are not diagnoses.

Use the session to describe symptoms more clearly at an eye appointment: distance, lighting, one eye versus both, and whether headaches or fatigue appear.

This tool does not determine ADD power, diagnose presbyopia, or validate over-the-counter readers.

It cannot distinguish dry eye, binocular vision issues, or medication effects from refractive causes.

Important limitations:

• Screen text rendering differs from printed near cards used in clinics.
• Auto-brightness and dark mode alter contrast.
• If you lean closer without noticing, you may underestimate difficulty.

Seek an eye exam if near work requires constant leaning in, if you need brighter light than before, if one eye is much worse, or if headaches accompany reading. Sudden near blur with other neurological symptoms needs prompt care.
