Saccade trainer.

Saccades are the fast, precise jumps your eyes make between points — the same skill you rely on when scanning a line of text or a room. This drill fires a target at the edges of your vision and times how quickly you can find it.

How to do this exercise

Sit at a comfortable distance from your screen, with the stage roughly at eye level.
Keep your head still and let only your eyes move to find each target — that's what trains the saccade itself.
Pick Horizontal for the classic left/right drill, or Scatter for random positions.
When a target appears, respond as fast as you can: click or tap it, or in Horizontal mode press the matching arrow key.
Choose a session length and difficulty, then start. Stop any time — your progress up to that point still counts.

Set up your session

Choose how the targets should move and how challenging you'd like the drill to be, then start when ready.

Mode

Targets alternate left and right of center — the classic saccade drill.

Session length

Difficulty

Higher difficulty shrinks the target, spreads it further out, and shortens how long it waits for you.

Clinical background

The science behind this

Saccades are the fast, ballistic jumps — up to roughly 500°/second — that snap your fovea from one point of interest to the next. You make several every second while reading, generated by a network spanning the superior colliculus and frontal eye fields.

Accurate, efficient saccades underpin fluent reading and visual scanning; sluggish or inaccurate saccadic control is linked to slower reading and is a target of oculomotor therapy. Reaction-time and accuracy feedback trains both speed and precision.
