    Should I be concerned that my eye prescription has changed so much in 3 years?

    Should I be concerned that my eye prescription has changed so much in 3 years? 3rd Dec 17 at 2:30 PM
    In February 2015 i went to the opticians and was prescribed glasses. My prescription was:

    Right - SPH +0.75, CYL -0.25, AXIS 90

    Left - SPH +1.00, CYL -0.75, AXIS 100

    I recently went to the opticians and it seems to have changed enormously:

    Right - SPH +3.50, CYL -1.00, AXIS 90

    Left - SPH +3.00, CYL -1.00, AXIS 90

    Is this something that I should be concerned about? It seems a pretty big change in 3 years?
    For reference, I am 23 now so was 20 at my last eye test.

    What did your optician say when you asked them?
    All shall be well, and all shall be well, and all manner of things shall be well.

    Pedant alert - it's could have, not could of.

    I have never needed glasses so the figures do not really mean much to me.

    Diet can play a big part and so can regularly changing focus to exercise the eyes. Collagen is important to the body and to the eyes and vitamin c is essential for it's formation. Smoking reduces vit c levels which is why smokers skin ages faster. There are a few different forms of collagen in the body used for different purposes. Collagen is formed from amino acids, with glycine being required most, with proline, lysine and others in smaller amounts. Lysine is an essential amino acid but glycine and proline can be made by the body but this can be insufficient. Bone broth soup or maybe gelatin provides these amino acids. These amino acid powders can be purchased but be aware that Glycine influences GABA levels which can promote sleep unless other stimulating amino acids are consumed. High protein foods can promote sleep too for a similar reason.

    Anthocyanidins/Proanthocyanidins can also be helpful as they strengthen collagen and bones and are also antioxidants. They can also help the circulatory system
    Anthocyanidins are present in many foods to some degree as they provide natural colour to fruit and veg. They are more highly concentrated in black/blue/red berries such as cherries, blueberries, blackberries, elderberries or hawthorn berries etc.

    These all work together, the more you take the bigger the improvement.

    It's a relatively big change. Assuming it's correct (have you changed your glasses yet?) the new prescription should work a lot better especially for near, but may take some getting used to.

    We do see this sometimes in young people. Long sight can be masked or overcome by the eye's focussing system. During an eye examination we try to get this system to relax but it remains active in some young people, so the older prescription might be too weak - in other words you may have always had a prescription that high. It's just revealing itself as your focussing system weakens as you age.

    So no, it's probably nothing to worry about.

    The previous answer is bull**it, by the way. I'm an Optometrist.
