How to check (one eye at a time)

❶ From the screen that appears when you press "Start Self-Check"
Check from a distance of 20-30 cm.

❷ Cover one eye with your hand and stare intently at the star in the center.

❸ Check if there are any areas in the sandstorm that are difficult to see.

❹ Check your other eye as well.

If it looks like this, be careful!!

*The image is an example.

It's a little darker than other places.
There are some blurry parts.

*We recommend checking this on a larger screen, such as a computer, rather than a smartphone.
