Bifocal Reading Glasses

After my stepmother refused to use his 3rd pair of bifocals (problems with the average distances and the general operations), we began to discuss the view. She wore reading glasses for about 10 years now, about 3.5. With them on, she can read perfectly fine, fine watch TV and see them distended with large fine. However, it is also short-sighted as well be long sighted with his reading glasses off, she can not watch television or drive without them. I can not help how his reading glasses myopia.

What happens there is some confusion about hyperopia (farsightedness) and presbyopia.

+ Hyperopics wear glasses both far and near, while presbyopic only need reading glasses and can not see distance with them. A hyperopic + power needs even stronger for the near vision power + added to the distance once they are in their 40s .... So ... bifocals.

It is certainly farsighted, and age, probably early 50s, she is also sighted.

I bet if you saw the actual prescription, it is something like + 2.50 for the distance, with a 1.75 + Add to reading ... thus giving a total power of + 4.25 for relatives.

Thus, with 3.50 + glasses, it has more than its correct distance vision and presbyopia undercorrecting, but now it is a compromise both with the power it carries.

But it was not myopic at the very least, it is farsighted and presbyopic ...

Your step-mother did not worry about myopia. It is "long view."
It is farsighted.
It takes two more drinks at a distance and nearby.
Glasses reading glasses are known lentils more. They correct the farsightedness.

Varifocal may get better, similar to bifocals, but you do not see the dividing line between differences.Saves the purchase of 2 pairs as well. Make sure it goes to a good optician for proper fittings etc.
