Free online eye tests

Choose a vision screening

Start with our most popular color blind test, or choose another free screening for visual acuity, astigmatism, contrast, peripheral vision, central vision or eye teaming.

Online screening has limits

These tools are designed for screening and education. They cannot diagnose an eye condition or replace a complete examination by an optometrist or ophthalmologist. Seek professional care for sudden vision changes, eye pain, new double vision, flashes, new floaters or persistent concerns.
