I’ve had to have another eye test after only a year.
I’ve had a constant “strained” feeling in my left eye for a long while now and I did not think that my prescription in my left eye (My bad one) was strong enough.
I was surprised to find that my new eye test produced a prescription that actually was not a strong (change of -0.5 Sph - from +5.50 to +5.00)
New Prescription is:
Right: SPH +2.75 CYL -0.5 AXIS 95
Left: SPH +5.00 CYL -2.50 AXIS 1.50
There was a notable change in the axis on my prescription. How much can the axis affect the prescription?
Until now I have always had the strained feeling in my left eye and it does not seem as if the eye can quite focus properly.
Does anyone know if the Visual results of a prescription that is too weak (out of focus) would look the same as one that’s too strong?
Answer:
It sounds like you have an amblyopic left eye (lazy eye), which is why your vision won’t improve with a pin hole. The vision through your left eye will never be as good as your right eye no matter what prescription if put in front of it.
For hyperopes, over correction of your prescription can lead to excessive blurring. Undercorrection can be compensated for by the eyes, as they can easily overfocus to correct for it, and so it is less noticeable.
The impact of the change in axis is dependent on the size of the cylinder component in your precription. This is very small in your right eye, so a huge change in the axis will have a minimal impact on vision for that eye. However, for your left eye, where the cylinder is much higher, even a small change in the axis can have a significant impact on vision
Edit: Yes, you’ll be superior off with the weaker prescription. Your old one will just cause more blur and a greater mismatch between your two eyes. The new prescription should have both eyes as closely balances as possible given you’ve a lazy eye
Answer:
Do you see ghosting from you left eye ?
try looking through a pinhole. does it make you feel better. Did your physician tell you’ve blended stigmatism?
