Check how small a line of text you can read comfortably at a near reading distance. Get a rough reading-card style near vision summary and practical next-step guidance for home screening.
Use this near vision test to screen how small a line of text you can read comfortably at a measured reading distance. It is a quick reading-card style screen, not a prescription tool. Compare it with the Visual Acuity Test or the Eye Strain Calculator.
Choose the eye, correction, and reading distance you are using. Then pick the smallest text block that still feels comfortably readable.
Pick the smallest line size that still feels readable without straining or guessing word shapes.
A near vision test checks how small a line of text you can read at a standard reading distance. Unlike a distance chart, this type of screen focuses on reading-card style print sizes that matter for books, menus, phones, labels, and other close-up tasks.
This tool provides a rough home-style screen for near text only. It is not a prescription test, but it can help you notice whether your comfortable reading size seems larger than expected. For more eye checks, browse the Eye Check & Assessment category.
The tool shows several reading-card style text sizes from large print down to small print. You choose the smallest line size you can still read comfortably at your selected reading distance, then the tool gives a rough screening interpretation based on that level.
Pick the eye, correction, and reading distance you are using for the test.
Move through the text sizes and note the smallest line that still feels comfortably readable.
Choose the smallest comfortable line, not just the smallest line you might force yourself through.
The result describes whether the chosen line sits in a large-print, general-reading, or small-print near range.
Example: if you are testing both eyes with reading glasses at 40 cm and the N10 line is the smallest one that still feels comfortable to read, the tool will place you in a functional everyday near-reading range. That does not replace a proper refraction, but it helps describe your near-text comfort in practical terms.
If near reading feels tiring rather than simply blurry, compare the result with the Eye Strain Calculator to see whether screen strain may also be contributing.
A phone, tablet, and laptop do not present the same text size unless the display is calibrated.
Zoom, operating system text scaling, and accessibility settings change the effective print size immediately.
Dim rooms or glare can make near text feel smaller or less comfortable than usual.
Even a small change in reading distance can change how easy the text feels to read.
Using the wrong glasses or skipping your usual reading correction can shift the result a lot.
A proper near-vision exam checks more than print size, including prescription accuracy and other causes of blur.
Use it to compare near-text screening with a rough distance-vision result.
Helpful for displaying a distance chart while comparing close-up and far vision tasks.
Useful when reading discomfort feels tiring or dry rather than only blurry.

No. It only screens how small a line of text feels readable on your current screen setup.
That is often useful, especially if one eye seems weaker or if both eyes together feel easier than each eye alone.
That generally means the displayed card range did not find a clear limit on this screen. It does not prove perfect near vision.
Because zoom changes the effective print size, which makes the result much less meaningful as a comparison.
That can happen with presbyopia, near correction needs, fatigue, dryness, or other issues, so a proper near-vision exam may still be useful.
