I think my bifocal prescription may be wrong?

The Nashville VA sent me to a 3rd party for a prescription. It was a 5 minute eye exam & a 5 minute eyeglass prescription exam. The bifocal (Add) has 2.50 for both eyes. My right eye comes into focus from about 16" away. My left eye comes into perfect focus about 8" away. Before I spend $ on glasses, is Add 2.50 correct for both eyes?

If both lenses are actually made to Rx correctly, and the bifocals don't focus at the same distance, the distance Rx is wrong. The 2.50 refers to the additional power at near required over and above what is required at distance, and is always the same for both eyes.

LIke GJG said, the Rx is wrong.

And a 5 minute eyeglass prescription exam is nowhere near long enough to do the job properly.

15 to 20 minutes is more like it.

Not that I'm blaming you; this isn't your first prescription glasses, right? When I get my eyes checked, I always take my time.

When the person goes, "which is better, A or B?"

I don't mind if I ask the person to repeat the comparison even 3 or 4 times. No one has expressed frustration yet; they understand I want to get it right.

There's an unconscious desire to give the "right" answer and sometimes our minds trick us.

"It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual." Viktor Frankl, Man's Search for Meaning, 1946.
