About this website
Clearer information for safer at-home vision screening
AstigmatismTest.com provides free educational screening tools and practical guides that help people describe what they notice and prepare for a conversation with a qualified eye-care professional.
What we do
We build screen-based activities that can help users compare each eye and notice repeatable differences in lines, clarity, color, or distortion. We also publish explanations of common vision terms, test limitations, and signs that warrant professional care.
What we do not do
This site is not a clinic, telehealth service, or substitute for an eye exam. Our tools cannot diagnose astigmatism or another condition, measure a prescription, or examine the health of the eye. We do not provide individualized medical advice.
Who maintains the site
Content is maintained by the AstigmatismTest.com Editorial Team. That name identifies the people responsible for researching, editing, and maintaining the site; it is not the name of a medical practice or a claim of clinical credentials. We currently do not represent our articles as having been reviewed by a licensed optometrist or ophthalmologist unless a future page explicitly names a verifiable reviewer.
How we prepare content
Start with reliable sources
We prefer government health resources, professional eye-care organizations, primary research, and established clinical guidance.
Check claims and context
A person reviews factual claims, limitations, source relevance, and final wording. AI-assisted tools may help organize research or improve a draft, but they do not replace human checking.
Keep commercial influence separate
Advertising may help support the site, but advertisers do not choose our topics, approve our conclusions, or receive disguised editorial endorsements.
Questions or corrections
We welcome specific corrections, source suggestions, accessibility reports, and questions about how the site works. Include the page URL and the passage or behavior you are reporting so we can investigate it.
