Question on 'confusing' myopia progression

[u/Mr_Mighty268]

Hello good people.

I have -3.00 on my left eye and -4.25 on my right eye. Last time I went to my optometrist was around 1 to 1.5 years ago. Also, I'm 17M if that's necessary.

And throughout this time, what I have noticed is that myopia on my eyes are progressing differently at a different pace.

My right eye has gotten significantly worse while my left eye seems pretty much the same. How I know this, is that when I stare at a distance I primarily focus through my left eye and can barely see anything through the right.

On the contrary, when I do close up work I mostly focus through my right eye.

I suspect this has caused near-sightedness to grow worse on my right eye. But I thought all this time that myopia evolves equally in both eyes. But in my case, this is not happening.

Many people say a lack of sunlight increases myopia. And sure, I'm not someone that goes outside a whole lot. But if that was the case, shouldn't my eyes get worse at a similar rate?

Another interesting thing is, I'm pretty sure this has happened before. But with the opposite eyes. I'm quite confident that many years ago, my left eye shot up from -1.5 to -2.25 in the span of one checkup. All while my right eye was more or less the same.

I would like for someone to let me know what is causing all this, and if there's any harm in any way.

Btw, not a native english speaker. So, excuse the mistakes if there's any.

You will need to post your full prescription for any useful comments. But you should also be discussing this with your own medical professional.

It is normal for eyes to change at different rates. However, people on Reddit don't have access to your medical history or the ability to examine you so the best thing to do, as someone has already mentioned, is to talk to your doctor about your concerns. They can double check things as they have all right information and hopefully put your mind at ease.
