Ever worried that the street signs are getting blurrier? Vision Test can calm your fears—or get you to the optometrist. The app conducts basic tests for visual issues such as astigmatism and visual acuity (standard clarity of vision, usually described in the 20/20 format), among others. If your test results indicate an issue that needs professional correction, it will recommend you visit an optician and even help you find one. Available for iPhone and Android.
