Rifle Scopes Will a scope correct my vison?

[sobrbiker883]

Here's the question, if I'm nearsighted and wear glasses for distance will my scope make up for that? I set my diopter for reticle clarity, and adjust my objective so I have no parallax, and I'm having a hard time focusing on small precision targets on paper at 100.
I was blaming my scope for not being clear when the parallax is dialed out, but driving home from the range today it occured to me that my prescription is old and I'm fuzzy at distance. It dawned on me that the magnified image may just be that, a magnified image that I still need my glases upraded for distance clarity through........

Mind you, its not a cheap glass problem, its the same with my USO SM3 and my new ST10.

To answer your question simply, yes, well in my case it did and continues. When I started shooting allot, 3 years ago my perscription for contacts was X. Over time, my vision in my dominant eye has become better each of the last 3 yrs based upon my perscription strength. My eye doctor shoots as well and noticed an inmprovement year after year. Not that I understand all of it but my eyes have gotton better, to paraphrase "small motor skills of your scope eye" I dont know the clinical definition but it has gotton better

If you are simply near- or far-sighted, then the diopter adjustment will make up for it. The diopter control (on the ocular) allows you to achieve a sharp focus of the reticle for your vision. It won't make up for astigmatism, however.

The AO or side parallax control adjusts the focal point of the target image to be in the same plane as the reticle. Now both the reticle and target image are in focus at your eye.

I'm no eye doctor, but I can imagine you could still have a problem focusing your eyes at any distance, even without a scope in front of them. The muscles that control the lenses in your eyes get weaker as you get older.

I have noticed that if I use the AO to get the image clearer, I am at a higher yardage mark than my true distance (bear with me, I know most scopes don't match the markings..), and while the image is clearer, there is noticable parallax.
This is what led me to believe that mechanically the image and the reticle are on the same plane when parallax is dialed out (because it is a engineered mechanical distance, not subjective, such as focus to an individual's eye would be), and makes me wonder if the image is still blurry because parallax and focus are seperate animals.........

When you adjust the diopter for your eye to clear up the reticle + or - I was told it changes the parallex distance because they are set up to be in zero position on the Ocular.And when you change to a + or - that is why the yardage dosnt match the marking.I cant say for sure this is true or not for sure but it sounds reasonable.

That's what I've heard as well, but the scope/s is/are parallax free at the marked yardages, but when I use the AO to focus, there is noticable parallax.........

This is an interesting question, and I think you would do well to post it to www.6mmbr.com, where a member there -- Fred Bohl -- seems to have expertise in optics (and maybe vision?).

While questionable as to the potential of strengthening the dominant eye, it has been proven to strengthen one's dominant hand........

Not really. It just changes over time. I was nearsighted most of my life but the ophtalmologist told me my eyes would require less correction for distance with age. He was right as my correction dropped by a full diopter value over 30 years but then about 12-15 years ago, my arms started getting shorter for some reason.

Now that I can do without glasses for most everything except driving, I can't do any close work without a magnifying glass, my bifocals or my cheaters.

As for the scope, I shoot without corrective lenses of any kind. I do all the correction I need in the ocular and I the AO scale is just an estimation; there is no substitute for adjusting to your eye. If you still have a parallax problem when it is properly adjusted, you have an issue with the scope's internals. This is where the price you pay for a scope shows its worth.

To the OP, if you can't focus the scope to your eye, you realy should consult your eye doctor and explain the issue to him or her, I'm sure something can be done.
