Local reading instrument

Your reading geometry,
remembered.

Set type, spacing, line length, contrast, and a quiet focus band once. Eye Comfort Profiles brings that exact layout back when you return to the site.

Stop repeating the same adjustments.

01 / Calibrate

Tune the page, not your posture.

There is no “correct” font for every reader. Start with what feels easy, then save the combination—not a prescription.

Reading surface

Live reading sample

A layout that returns with you

Comfort can depend on the page, the hour, and the kind of reading. A narrow article may need generous spacing; a reference page may work better with compact lines.

Move these controls to test the geometry. The extension remembers the full combination for each hostname.

02 / Remember

Three moves. Then just read.

  1. 1

    Open a page

    Select the extension on any regular website. Protected browser pages remain untouched.

  2. 2

    Tune with live feedback

    Adjust type, size, spacing, line length, surface, and the optional moving focus band.

  3. 3

    Save to the site

    Name the profile and assign it. Settings return locally on every visit, with no account.

03 / Keep control

A profile system, not a diagnosis.

Four honest font stacks

System, humanist, serif, or mono fallbacks—never a claim that one face works for everyone.

Reading geometry

Set 36–96 character lines, leading, letter spacing, and text size independently.

Optional focus band

A translucent guide follows your pointer or keyboard focus without capturing clicks.

Local by design

Only your profile settings and hostname assignments are stored. Export or import them anytime.

A clear boundary

Comfort settings, not medical advice.

Eye Comfort Profiles changes presentation only. It does not test, diagnose, prevent, or treat any eye condition. Persistent pain or vision changes deserve advice from a qualified eye-care professional.
