Eye exams can help identify the problems that are related to your vision. So if you start to feel like there’s something wrong with your vision, it would be best to see your eye doctor. If you are still unsure whether you need to go for an eye check-up, you can perform a simple eye test for visual acuity online.
Test your visual acuity online
- First and foremost, you will need your smartphone (or tablet) as well as your computer. Make sure that your smartphone has a QR code scanner. You’ll also need to prepare a standard card or credit card for screen calibration.
- Next, open this link on your computer. The link will lead you to the homepage of an online eye test for nearsightedness called “Vision”. It’s free and you don’t need to register.
- On the homepage of Vision, scroll down the page then click “Try Now”.
- On the next page, you will be asked to calibrate your computer screen. Click the settings icon at the top.
- An overlay window will appear. Place your credit card at the left side (right inside the black border) and then calibrate your screen by moving the slider on the right. Calibrate your screen in such a way that the card field will only show the black border and not the gray area.
- Once done, close the overlay window and click the QR code icon from the Start here area.
- Scan the QR code using your phone or tablet. The QR code will open a test sheet on your phone’s mobile browser.
- Moving on, move at least 4 meters away from your computer screen.
- On your phone, tap each star or tile on the test sheet. You’ll then be asked to provide the correct letter based on the eye chart that is being shown on your computer.
- Complete all the tiles. If you enter the correct letter, the tile will be marked as green. If you enter the wrong letter, the tile will be marked as red. The results will be shown on your phone as well as your computer screen.
- Once you’re done, check your score to see whether you are having problems with your eyesight.
That’s it. Just remember that this test will only serve as a reference to see whether you really have a weak vision or not. You’ll still need to go to the eye doctor for a more thorough eye examination.
