Focal distance

I have recently had an eye test and been told I need stronger reading glasses. Having just collected these I find that I have to be no more than 30cms from the page for it to be in focus and anything beyond that is blurred, whereas with my old glasses (which are still fine to read with) I am at a more natural and comfortable 45cms and can sit at my desk and see things comfortably 75cms away.
I have returned to the optician who said that it is an age thing (I am 73) and I will need graduated lenses to be able to see clearly for a greater range.
I have never experienced this before with new glasses and makes me think that with my next pair of glasses I will have to hold the page even closer than 30cms.
Is this situation to be expected given my age and prescription?
My current prescription is:
R & L -0.25/-0.75 x 90 Add +2.50

Any advice on will be appreciated, thanks.

 

It takes some time to adjust to a new glass. It's pretty common at this age, and there's nothing to worry about. Your eye is adjusting to the new power. Give it some time. If the problem still persists, contact your optician.

 

Based on the prescription you provided, it appears that you have a mild nearsightedness (myopia) with a slight astigmatism correction and presbyopia, which is the natural age-related loss of near vision. The "+2.50" value in your prescription indicates the additional correction needed for near vision.

Given your age and prescription, it's not uncommon to experience changes in your vision and visual comfort over time
