Is this eyestrain?

[SebBernardo]

Hi.

This week I went to a doctor since I have noticed my vision has worsened. In two years, the left eye stayed the same but the right eye went from -1.75 to -3.00.
I also went to an OCT scan, since the doctor suspected something. It turned out that I have a difference between my two eyes (I think it was something to do with a cup to disc ratio, but I'm not sure), and I will have to go to the doctors again in 3 months so we can see if this difference is developing now or is there from my birth.

The doctor has told me that she doesn't think it is developing now though.

She has also told me that I should replace my glasses as soon as possible, however I will do that next week on Saturday, since I'm abroad.
I have noticed that I get this strange feeling on my right eye, but it seems to me like it's getting stronger the more I work with the eye, since I don't feel it in the morning... It's not really pain, it's more like an uncomfortable feeling behind the eye, it feels like the eye muscle is tired or something...
My doctor also said that my eye pressure is very good.

Can someone please answer these questions for me?:

Is this eye strain? If yes, is it normal that the right eye gets more tired because the right lens on my glasses is weak?

Will my eyesight worsen in one week that I will be wearing weaker glasses?

Since my glasses are weaker, should I continue to wear them until I get new ones?

How can I treat this feeling, should I get eye drops or pills or something?

Thanks.

I'm 16, if that helps.

But wouldn't there be other symptoms than diabetes? Because I'm actually healthy, I have medical problems very rarely. I haven't really had any serious medical issues, except a yellow fever after my birth.


Also, what is cataract and what are the symptoms?

I am really worried and scared now, although this feeling in my eye and change in vision over two years time is the only thing that I have, no other symptoms of anything.

Are those examinations such as cycloplegic refraction necessary if I get new glasses?

Thank You.

Your eyes will not be damaged by wearing the old glasses for a week.  You do not state your age, but that is a significant change in one eye.  If you saw an optometrist, you should see an ophthalmologist to be sure that there is no diabetes or cataract causing the change.  Diabetes would likely cause a change in both eyes.  It is possible that your symptoms are due to eyestrain and, if so, should resolve when you wear the proper prescription.  See the ophthalmologist first before obtaining new glasses; a cycloplegic refraction should also be done.  This checks the eye prescription after the pupils are dilated, in order to relax the focusing muscles and be sure the prescription is correct.
