half of my perscription?

Hello,

I have been short sighted for as long as I remember. I wear glasses for everything and I have asitmatism. I have been reading online techniques to exercise your eyes to stop your eyesight getting worse. Once technique requires you to buy glasses that are half of your perscription.

I have been told to get glasses half of my perscription I need to go 2 or 3 dioptres weaker than my current. All the information I have found on this mentions sph and diotres however my printed out perscription only shows my SPH, CYL and AXIS for each eye. It does not mention dioptres. I'm failing to see the relation between dioptres and whats on my perscription. My perscription:

Right:
SPH CYL AXIS
-2.50 -4.5 8.5

Left:
SPH CRL AXIS
-3.00 -3.00 8.5

Am I correct in thinking that if I change that to

Right:
SPH CYL AXIS
-1.50 -2.5 8.5

Left:
SPH CRL AXIS
-2.00 -1.00 8.5

I would have around-about halfed my perscription?

Any advice on this would be much appreciated.
Warm Regards,

You have been misinformed. There is no truth in what you were told. All you will do with half strength glasses is have blurry distant vision.  There is NO scientific way to stop myopia from progressing just like there is no way to stop your height growth when you decide you're tall enough.

Thanks for your reply John.

As far as I'm aware your eye has muscles just like any part of your body - effectivly wearing glasses is the same as sitting in a wheel chair all day every day.

It makes sense to me that if you exercise your eyes, they will improve?
