I Can't See: Low Vision A11y & Users
summary
Low vision means impairments that glasses cannot fix, including color vision deficits, reduced acuity and contrast sensitivity; global counts cite about 1.4 billion people with disabilities and 1 in 12 men affected by color deficiency. Practical rules: never disable zoom, never rely on color alone for meaning, prefer readable typography and icons with text. Tools and checks shown include axe + Lighthouse in the browser; automated audits catch roughly 20–55% of issues and WCAG AA requires at least 4.5:1 contrast.
