Display Accommodations

Invert colors, reduce white point (brightness), enable grayscale, or apply color filters for different types of color blindness. Found in System Settings → Accessibility → Display.

Reduce Motion

Minimizes animation throughout macOS. Websites that respect this setting (like this one) will also reduce motion when this is enabled.

Switch Control

For users who interact with a single switch or limited switches. Scans through interface elements and performs actions when switch is activated.

Windows Accessibility Features

Windows provides extensive accessibility features in Settings → Accessibility. Key features include:

Narrator (Screen Reader)

Understanding Visual Conditions

How different conditions affect web browsing and which features help.

Achromatopsia

What it is: A rare inherited condition affecting about 1 in 30,000 people. Causes complete or near-complete color blindness, severe light sensitivity (photophobia), and reduced visual acuity.

How it affects web browsing:

Bright screens cause physical discomfort and eye pain
Colors are seen as shades of gray
Fine details may be difficult to perceive
Standard white backgrounds are painful to view

Helpful features on this site:

Dark mode (default) significantly reduces light output
No information conveyed by color alone
High contrast mode provides clear text without brightness
Text size increase compensates for reduced acuity
Icons accompany color cues (success/error states)

Nystagmus

What it is: A condition causing involuntary, rapid, repetitive eye movements. Can be horizontal, vertical, or rotary. May be present from birth or acquired later.

How it affects web browsing:

Difficulty tracking lines of text
Small text is especially challenging to read
Moving content or animations are disorienting
Visual fatigue occurs faster than normal
Finding place after looking away is difficult

Helpful features on this site:

Reading guide helps track current line
Larger default text size (18px base)
Increased text spacing option
Reduce motion eliminates distracting animations
High contrast makes text boundaries clearer
No auto-playing content

Low Vision

What it is: Visual impairment that cannot be fully corrected with glasses, contacts, medicine, or surgery. Includes conditions like macular degeneration, glaucoma, diabetic retinopathy, and cataracts.

How it affects web browsing:

May see blur, blind spots, tunnel vision, or distortion
Small text is difficult or impossible to read
Low contrast text disappears entirely
May use screen magnification at 200-400%

Helpful features on this site:

Text scaling up to 200%
High contrast mode
Site reflows at high zoom (doesn't require horizontal scrolling)
Link highlighting makes clickable elements obvious
Large click targets (44×44 pixels minimum)

Color Blindness

What it is: Reduced ability to distinguish certain colors. Most common types are red-green (protanopia, deuteranopia) and blue-yellow (tritanopia). Affects about 8% of men and 0.5% of women.

How it affects web browsing:

Red and green may appear similar or identical
Color-coded information may be meaningless
Error messages relying only on red color may be missed
Graphs using only color distinctions are unreadable

Helpful features on this site:

No information conveyed by color alone
Icons and text accompany color indicators
Links are underlined, not just colored
Focus states use multiple indicators (color + outline)
System color filters work with this site's design
