This is the text (if you need help).
A device for smartphones can test our eyes. It can tell us how bad our eyes are, and then order glasses online. It is from a company called EyeQue. The company says the eye test is as good as the test from an optician. It already tested the eyes of 50,000 people. The device costs $30.
EyeQue said the device was helpful. It said the optician can be in a hurry and will do only one test. EyeQue takes many tests and averages them. This gives a better result. The device will not replace the optician. An optician checks for eye problems. The device cannot do this.
