Eye stretching

Do you sometimes feel your eyes getting blurry when using your phone?

It takes longer to focus these days as I get older,ㅠㅠ

So, there is a stretching exercise I do occasionally.

I think it becomes much clearer.

Close your eyes and rotate your eyeballs in an 8-shaped pattern sideways.

Do you know the shape of infinity?

It looks like that, but I can't draw it.

You should gently move it several times slowly in a sideways, tilted shape.

I also need to take eye supplements,ㅠ
