Vision Span Trainer

Hold your eyes on one point and notice what you can see around it. A focus exercise, with no promise of faster reading.

🎯 RULE:Keep your eyes on the center red dot and try to notice the words on each side without looking at them.

The Vision Span Trainer is an exercise where you hold your eyes on a center dot and try to notice words on both sides. It's good practice for steady focus. Research has not shown that this kind of training widens the span you use in normal reading, so don't expect it to raise your speed on its own (Rayner et al., 2016).

Lexi's Focus Tip

READING COACH
Keep your eyes on the red dot and notice how little you can read clearly away from it. If your eyes feel tired, stop. This is focus practice, and real reading will do more for your speed.

How to Use the Vision Span Trainer

Three steps, a few minutes at a time:

1Look at the Dot

Sit 50 to 70 cm away from your screen. Keep your eyes on the red dot in the center, without looking left or right.

2Notice the Sides

Press Space to begin automatic pacing. Try to notice the words or letters on both sides as the lines get wider.

3Test Yourself

Toggle Recall Test: ON to flash word pairs for 300 ms. See what you can pick up without moving your eyes.

🧠 What Research Says

Does Vision Span Limit Your Reading Speed?

What the research says: Skilled readers take in useful information from about 3–4 letters left to about 14–15 letters right of where they are looking, limited mainly by visual acuity (Rayner et al., 2016). Claims that pyramid drills widen this enough to double reading speed are not supported by eye-tracking studies. These drills can still be a useful focus exercise.

When reading ordinary text, human eyes do not move smoothly across the line. Instead, they make abrupt, ballistic jumps called saccades, separated by stationary pauses called fixations. Eye-tracking research by Keith Rayner and colleagues found that each fixation lasts about 200 to 250 milliseconds (Rayner, 1998).

Your sharp vision covers only a small area around the point you're looking at:

  • Central vision (about 1°–2°): the sharpest area. It covers only a few letters at normal reading distance.
  • Just outside the center: blurrier, but you still pick up word lengths and the first letters of the next word.
  • Further out: you notice movement, layout and line ends, but you can't read words.
Speed reading claimWhat the evidence shows
Training cuts you to 2 or 3 stops per lineEye-tracking studies don't show this for readers who still understand the text (Rayner et al., 2016)
Training widens your span to whole linesUseful information comes from about 3–4 letters left to 14–15 letters right of your focus, limited by sharp vision
Trained readers stop going backGoing back helps comprehension: when readers can't re-read, they understand less (Schotter, Tran & Rayner, 2014)
Word pyramids transfer to readingTasks like this get better with practice, but that gain hasn't been shown to carry over to reading speed
Key takeaway: use these drills to practise focus. For faster reading, the best-supported approach is simply reading more, building vocabulary and knowing the topic (Rayner et al., 2016).

A Simple Practice Routine

Try this for a couple of weeks, then retest your reading to see whether it helps you:

STAGE 15 MINUTES

Letter Flashes

Select Alphanumeric L1 or L2. Lock your gaze onto the central red dot. Go line by line and note the outermost characters without moving your eyes.

STAGE 25 MINUTES

Word Expansion Pyramids

Switch to Word Pyramids. Set the pacing interval to 1.0–1.2 seconds. Look at the center dot and try to notice both words.

STAGE 35 MINUTES

Real Reading

Open a physical book or use our Reading Pacer. Read something you enjoy at your normal pace. This is the part most likely to help.

The Geometry of Vision: Calculating Visual Angle

The span shown at the top of the trainer is a visual angle, worked out with this formula:

θ = 2 × arctan( W / (2 × D) ) × (180 / π)

Where W is the physical width of the expanding text on your screen (converted from pixels to millimeters based on standard 96 DPI) and D is your viewing distance (calibrated at 600 mm / 60 cm).

  • Level 1 (Narrow Span): ~3.5° visual angle. Close to the center of your vision.
  • Level 7 (Intermediate): ~7.2° visual angle. Wider than the area you read from.
  • Level 14 (Widest): ~12.5° visual angle. Far outside the area you read from.

Frequently Asked Questions

Can expanding your peripheral vision increase reading speed?
While reading, your eyes stop (fixate) several times per line. At each stop you see only a few letters sharply, but you also pick up useful information, such as word length and the first letters of the next word, from up to about 14–15 letters to the right of where you are looking (Rayner et al., 2016). Speed reading courses claim that widening this span cuts fixations to 2 or 3 per line and doubles reading speed, but eye-tracking research does not support that: the area from which readers take in useful information is limited by visual acuity, and training has not been shown to expand it much (Rayner et al., 2016). Use these drills as focus practice and measure any change with a comprehension test.
What is a speed reading word pyramid drill?
A word pyramid is an eye-training exercise where text lines progressively widen as you move down the page. You keep your eyes on a center dot and try to notice the words on both sides without looking at them. It is good practice for holding your focus, but it has not been shown to raise reading speed.
How does the letter and number drill work?
It shows random letters, numbers and symbols at growing distances from a center dot. Because they don’t form words, you can’t guess them from context, so it shows you how quickly sharp vision falls away from the point you’re looking at.
How long should I practice vision span exercises each day?
Five to ten minutes is plenty. Short, regular sessions are easier on your eyes, and there is no research-backed schedule for these drills. Stop if your eyes feel tired. If your goal is reading speed, time spent reading real books is likely to help more (Rayner et al., 2016).
What is the ideal distance from the screen during eye training?
A normal, comfortable viewing distance is fine, roughly an arm’s length, with the screen at eye level. Keep your head still during a drill so that only your attention moves, not your eyes. If you have to lean in or squint to see the outer words, make the text bigger rather than moving closer.
