Spectacle Prescription of sphere +0.25 and add +0.50. What does it mean?
So i went and got my eyes tested for the first time the other day and i came out a little confused. I am having some eye strain issues from working on my computer so often as well as doing detailed paintings and embroidery.
The optometrist said I was far sighted and gave me a prescription saying Sphere: +0.25 (in each eye) and Add +0.50 (for each eye). I had to leave the optometrist straight after test and it wasn't explained to me completely what this meant. So I went to check out those reading glasses at the chemist and they only have +1.00. Does my prescription mean i should wear +0.25 or +0.50 glasses.
Will using the +1.00 be bad for my eyes when using them for my computer and embroidery work?
Should i go back to the optometrist and potentially pay more for frames and lenses?
The +0.25 is a correction for farsightedness (hyperopia) and is actually for distsnce vision. While a slight correction it is distance vision.
The ADD correction is for reading and gets "added" to to the first meaning your full correction for near vision is +0.75 - when added together. Bifocal or progressive lenses might be one option.
And a low priced +1.0 is a fine test for resding, but +0.75 overcorrected for distance vision. But your reading correction is probably your main need.
Good luck. I under your situation as I wear glasses for the same reasons but mine need to be much stronger ( +2.75 and ADD 2.50 )
Farsightedness is greater difficulty seeing near objects than distant objects. Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak. The +0.25 in your prescription is to correct your farsightedness.
Farsightedness is often present from birth, but when you are young you have a very flexible eye lens, which helps make up for the problem.As aging occurs, glasses may be required to correct the vision.
Add power is the added magnifying power applied to the bottom part of multifocal lenses to correct presbyopia (a condition in which the lens of the eye loses its ability to focus, making it difficult to see objects up close), it will range from +0.75 to +3.00 D. Your add power is +0.50 in each eye.
You will be better off getting the prescription your optometrist gave you because it is specific for your eyes and your working distance. The over the counter reading glasses are not custom made for your eyes. They will probably still work, but may cause eye strain if they are too strong.
HI you have very mild long sigtedness, you can get away without wearing glasses at all, you wn really notice any difference when your not wearing them, you have ver mild reading rx too, if you add the 0.25 and 0.50 your reading rx is 0.75 which is not much at all.you could get away without wearing the glasses they will only make thing sharper and little bit clearer, thats all.
Hope this helps ive been wearing glasses all my life im in double figures
