What is the criterion for distinguishing between presbyopia and vision deterioration as we age?

My eyesight fluctuated between 1.2 and 0.8 during my student years, but as I got older, it started to decline.

It is gradually getting worse, fluctuating between 0.3 and 0.7. Of course, the two sides are not equal, and one side is

It's a bit worse. Since I was young, I have had a slight astigmatism, so things that are close up are generally okay, but...

As the distance increases, the image becomes slightly blurred, and at night, it appears thicker and more blurred due to the lights.

I'm wondering if my eyesight is gradually getting worse, but I still haven't been wearing glasses.

Recently, the nearby text sometimes appears blurry, but it doesn't last long and only feels that way for a moment.

It's a bit ambiguous to call it presbyopia. The typical sign of presbyopia is being able to see the text on your phone clearly when it's close, but having trouble when it's farther away.

There is nothing to watch out for. How should I distinguish between presbyopia and weakened eyesight?
