I am curious about the early symptoms and prevention methods of cataracts.

Hello? I am in my 40s. I haven't had good eyesight from the beginning, and I have high myopia and astigmatism, so I live as if I am blind without glasses.

I usually knew that around this age, presbyopia would occur and eyesight would deteriorate, but this year I've been experiencing increased eye fatigue and worsening vision, which has been concerning me.

Due to my profession, I am in an environment where I must look at a monitor for more than 10 hours a day.

Especially when driving at night, even with glasses on, glare is severe, making it very difficult.

I also experience severe eye fatigue, always feeling a stinging sensation, and on bad days, I feel a cold sensation, so I wear artificial tears all day long.

I don't think it's cataracts yet, but during the last health check-up, I was told that the distribution of the optic nerve in my left eye isn't very good, so I'm a bit worried.

I am leaving a question because I want to practice any early symptoms of cataracts and good prevention methods.

Thank you.
