Overview

Product summary

Review the store description, core capabilities, and common use cases.

Version 2.0.7: Upgrade to Manifest V3

Version 2.0.4: Bug-fixes and updated style.

As well as being a great general purpose screen dimmer, Visor's overlays and point of focus feature may be assistive to users with visual perceptual difficulties such as Dyslexia, Scotopic Sensitivity Syndrome and Visual Stress.

Whilst research shows results vary from person to person, some users may find that the use of overlays can help with fluency, eye-strain, concentration and comprehension whilst reading.

In addition to the traditional overlay method, Visor also employs a point of focus feature, designed to further reduce visual confusions and the tendency to skip lines.

This horizontal focal point tracks your mouse, giving full focus to the content being read, whilst reducing the visual noise of the surrounding page.

The only issue i have is how the app needs to be activated when you change tabs or pages. Would be five stars if the settings were universally applied until turned off manually.

RAGHAVAN2016年6月17日

Good

Gary2016年6月9日

Good idea and works well if you are staying on one page. So if you are reading a long article or watching something it's great. But if you're browsing and switching pages you need to re-apply each time you switch a page or a tab. Would give 5 stars if it could be applied and stay applied, but as it is right now it's almost unusable.

This is perfect, not just selecting white, it's an entire page dimmer. Love it.

Christopher Nguyen2016年5月18日

Great page dimmer! Exactly what I've been looking for!

Adrian A2016年3月31日

~If not for this one thing it'd be perfect. Make it automatically be on on all tabs, cuz right now you have to click the icon for each tab individually. ~No special unnecessary, shady, nosey permissions. ~Safe. ~Set it to how you please. ****TIP****: to just dim the page without color tint: turn all 3 colors to 0 and do the same with the 5th-bar(unless of course you like and/or want/need it) and simply slide the 4th-bar to your liking. And there you go it grays/dims the page, color-free.

Paul Johnston2015年4月12日

AI product read

Screen dimmer and reading aid that overlays a customizable colored tint on web pages with a mouse-tracking horizontal focus band

Helps users with visual perceptual difficulties (dyslexia, scotopic sensitivity syndrome, visual stress) reduce eye strain and improve reading fluency, concentration, and comprehension by dimming surrounding content and highlighting the area being read

User clicks the extension icon to activate. The popup appears with sliders for Red, Green, Blue (overlay color), Alpha (overlay opacity), and Focus (height of the clear reading band). The overlay tints the entire page, and a transparent horizontal band follows the mouse cursor, dimming everything except the line being read. Settings are saved automatically and persist. Clicking the close button on the popup removes the overlay from the current tab.

Target users: Users with dyslexia or visual perceptual difficulties / Users with scotopic sensitivity syndrome or visual stress / People experiencing eye strain from screen reading / Anyone wanting to reduce visual noise while reading online

Two image assets (visor-plus.png, visor-plus-large.png) exist in the assets folder but are not referenced in any source code — their purpose is unclear but they do not affect functionality.
The extension must be reactivated on each page load as stated in the store description (no persistent content script injection).

Monetization

No paid features detected

The extension has no payment UI, no billing APIs, no license checks, no feature gating, and no subscription logic. The 'upgrade' keyword hits are all from the third-party Material Design Lite library's CSS class names (e.g., .is-upgraded, .browserupgrade), not related to paid upgrades. The 'license' hits are Apache 2.0 license headers in the same third-party library. Two unused image assets (visor-plus.png, visor-plus-large.png) exist in the assets folder but are not referenced in any source code — they may be leftover or planned assets, but no code gates features behind them. All features (overlay color, alpha, focus tracking) are available to all users without any payment.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is entirely local and self-contained. It uses chrome.storage.local for persisting user preferences, chrome.scripting for injecting overlay CSS/JS into web pages, and chrome.runtime for internal messaging. There is no authentication, no account creation, no network calls to external services, and no login UI of any kind.
