My prescription has changed?

Question

I went for an eye exam today and the optician said my eyesight had improved. My prescription changed from

R -2.75 -0.25 x 140 L -2.25 to

R -2.50 -0.50 x 140 L -2

I went in expecting it to increase. I had been thinking my eyesight was getting worse and expected to be told I should wear them all the time. Anyone had a similar situation? Is this common? Is this really an improvement? I feel my eyesight is getting worse not better. Should I wear them all the time or not?

Answer 1

Your eyes will constantly change, sometimes they will get better and other times they will deteriorate. This is common practice. The prescription change itself is only minimal anyway...also people with similar prescriptions to yours more than often wear there glasses full time. It will not do your eyes any harm to wear them. Your optometrist would probably have advised you to wear them for most distance vision tasks especially concentrated ones like driving.

Answer 2

You would be the best judge of that, as far as wearing them all the time. I would suspect you would want to based on that correction. The actual difference between the 2 Rx's is minor, and actually not that much different. Your old correction would make you a little bit over corrected, so it may be slightly sharper with the new Rx.

Answer 3

The change in the right is is effectively negligible and the change in the left is only by one click of the lens (the smallest possible).  You could go back tomorrow and have that click come back.  The eyes are dynamic and your ability to see is affected by how tired you are, if you have dry eyes, allergies, etc.  As a rule this is a neglibile change over all.  If you get the new glasses, wear them for distance but you probably don't really need them to read.  If the glasses feel weird after a week, call the doctor.

Answer 4

ONe thing I thought of maybe the equipment used is different.  They tell women to get mamograms on the same equipment each year, so differences are true differences, and not differences caused by different equipment.

I just got glasses myself, and I'm not crazy about them.



Eat well and protect them from the sun.
