prescription questionsPrescription Questions?

I couple months ago I went to get my vision checked, since I was having some issues reading up close. It turned out that I'm farsighted, so the doctor gave me a prescription. I went back a week later to have my pupils dilated, and when the drops put in my eyes, took effect, I couldn't see anything.
The doctor said that me not being able to see from far away with my pupils dilated, meant that my prescription was much, much higher. After examining me, it turned out that my left eye prescription is +2.75 and my right is +3.50. Totally off from his initial prescription of +1.00 and +1.50.
He said I couldn't get all the prescription at once, because I was not going to be able to handle it, and that he would gradually increase it. I know with time my vision will most likely get worse and my prescription will need to be increased.
I can still see perfectly, the only thing is that things that I could read from a closer range, I now have to put a little farther away from my eyes to focus on it, but it's not like I have to put it 50 feet away.
My question is, what's the reason from having to reach such high prescriptions in a short period of time? if my vision is still good, I can still see fine from far away and can still read from a "normal" distance. Will my vision get really bad from one day to the other?
He didn't give me an explanation as to why, and I'm very curious to know why.
Sorry for the long story, thanks for the help!!


See a different optometrist. I'm not going to accuse anyone of anything, but that's my advice.
Hi

As an ophthalmologist faced commonly with this problem.
yes ,this perscripation is too high for you.
offcourseprescription questions ,your true refraction (after drop) is +2.75 and +3.50
but your gasses depends on your age closely because of your eye accomodation status
for example if you are 20 it is about +0.75 and +1.75
if you are older 45 it may be +2.75 and +3.5
last, if you see clear easily without glasses, dont ude it at all !
People who have hyperopia (need a "+" prescription), like yourself, have "short" eye balls. To see clearly, the rays of light from whatever object we're looking at must fall on the retina. (the retina is the back part of the eye that turns light signals into electric signals, which are sent to the brain). With hyperopia, the rays of light automatically fall behind the retina. To focus the light on your retina (to see clearly), you can accommodate (change the shape of the lens inside your eye) OR you can focus the light with an outside lens (glasses or contacts).

When we're young, we have a great ability to accommodate. As we age, the lens inside our eye hardens. This happens to everyone. When you were younger you had more flexibility in the lens inside your eye so you could "compensate" for your eye being a little short. You have to accommodate a little to see clearly in the distance. (sounds like this is no problem for your lens). For everyone, it takes more accommodation to see clearly up close (about 3 diopters of focussing power at 1/3 of a meter). This gets harder as the lens inside our eyes starts to harden with age (again, normal).

The dilating drops you were given temporarily paralyzed the muscles in the eye that can change the shape of the lens in your eye. This allows your doctor to take an objective meaprescription questionssure of what sort of prescription you may need (without you being able to accommodate your lens, which is probably what you did before you got the eye drops without even knowing it) All along your prescription was closer to what your doctor found after you had your eyes dilated. Your prescription didn't change suddenly, the drops just forced the muscles that change the shape of your lens to relax.

When people are older than approximately elementary school and are hyperopic, like yourself, it is often quite a "shock" to your visual system to suddenly switch to using glasses or contacts in their full strength to see clearly, when all along you had just been changing the shape of your lens in your eye. It sounds like this is the reason your doctor didn't want to give you your "full prescription" all at once. Some adults who have some hyperopia never "accept" their full prescription.

I think your glasses (or contacts) will make you more comfortable, especially for reading. I would recommend going to an optical shop that will allow you to get different lenses for free if your doctor increases the amount of prescription he wants you to wear. (some optical shops do this within a certain time period).

PS- after reading your note, maybe you can ask your doctor if you can use your glasses mainly for reading. They'll probably be the most helpful at near. Also, with such a "wimpy" prescription- ask if you can try over the counter glasses- they're cheaper.
