What is an astigmatism test?
An astigmatism test is a visual screening (usually using radiating lines or a Siemens Star chart) used to detect refractive errors in your eye. It evaluates if your cornea or lens has an irregular curvature.
How to check astigmatism online?
You can check astigmatism online by using an interactive radiating line chart. Cover one eye, look at the center of the chart from about 1 meter away, and observe if any lines look darker or blurrier.
Can I test for astigmatism at home?
Yes, you can perform a preliminary test for astigmatism at home using standard radiating fan charts. While helpful for screening, a home test does not replace an eye doctor's visit.
Is an online astigmatism test accurate?
An online astigmatism test is a screening tool. It is accurate for raising awareness and indicating possible vision problems, but a professional eye check is required for diagnostic prescription.
