Eyeque Visioncheck 2
Shameka Roessler
The EyeQue VisionCheck is a tool that you can use to measure the lens power needed to correct nearsightedness, farsightedness, astigmatism, and near vision ADD. Once the test is completed, you are given your prescription details, and can order glasses if you need them.
The VisionCheck is then secured with the included silicone strap. The strap rested right over the power button on my Huawei P30 Pro and kept powering off the phone. I ended up having to use the loosest setting on the strap.
This machine is called an Auto-Refractor and as you look at the barn or balloon, the machine will shine light into your eye and automatically adjust the focus to measure the shape and size of your cornea to provide the doctor with a base prescription.
The VisionCheck projects images from your smartphone screen through your pupil and onto your retina. Your refractive error (nearsightedness, farsightedness, and astigmatism) causes you to see these images in a certain way. Based on the way you conduct the vision test, our technology calculates your EyeGlass Numbers; the power needed to correct your refractive error.
You remove your glasses (if you wear them) and test one eye at a time. Each test has 9 steps where you overlap a red and green bar by pressing the buttons on the VisionCheck device until the bar turns yellow. At that point, the bars rotate into a different position on the screen and you overlap them again and so on for 9 times.
A full test of both eyes takes as long as you need to take in order to overlap the bars. There is no time limit. I actually became pretty fast at it. That said, I had to take the tests several times before the software gave me a prescription that I could use to order glasses.
Except that there are many ocular problems that make no change in your glasses prescription. And most prescriptions are unlikely to change much, if at all, during the year or two between visits. So this gadget might make a person feel like they are monitoring their eye health when the really are not. Pamela Dobson, DO Ophthalmologist
Before I deployed for Desert Storm in 1990, a military eye doctor used a similiar
Device to test get a prescription for my eyes. I did nothing but look into a device to see a barn image. He ordered military glasses with the prescription he got from that simple 5 second test. I could see perfectly with my new glasses. I was impressed. I asked my eye doctor this last time why she did not use this automatic method to get a prescription. She said the conventional eye test was better and more accurate. Really? I am not convinced. I will buy the eyeque device. It made a believer out of me.
