Are these symptoms of cataracts?

My father has been experiencing increasingly strange vision issues recently.

The writing appears blurry or objects far away become difficult to see, and the symptoms gradually worsened.

Meanwhile, the added symptom is that objects appear blurry as if something is covering the eyes.

When I look into the eyes, even with the naked eye, it seems like there is a thin white membrane covering the iris or something similar.

Is this the early symptom of cataracts... Even if I suggest going to the hospital, he doesn't listen... I'm worried. Should I force him to go anyway? ㅠㅠ
