Hi Laura
What exactly is your problem?
No, that is not a smartypants question – the idea is to try to get you to unpack a serious concern with your vision, into a clear idea of what may be going on.
Let’s start with your glasses. High street “Opticians” do not always get things right. I have taken two pairs of glasses back within an hour, because they were wrong. I put “Opticians” in quotes because most of them are not – they are in business to sell frames. The person who tests your eyes is an Optometrist, and he/she may be influenced by his /her company policy. You should have been given a copy of your prescription. Look at it carefully. It should give the lens strengths for distance vision and the corrections for astigmatism. The first two columns should be “sph” and “cyl”, and if you are short-sighted, the numbers should have a dash over them (the dash means a minus strength, and it is used to avoid confusion with a horizontal stroke in a number). Take a photocopy of the prescription if you were given one.
So, if there is no prescription, or if the numbers do not have that dash, then whoever did your test has got something wrong. After that, the next question is whether the glasses are actually to the prescription. Most “opticians” have the test equipment to see if the lenses are roughly right. What they do after you order the glasses is to send your chosen frames off to a real Optician, who will either order the lenses in or cut then in-house. These come as a disk which is then fitted to your frames so that the optical centre of the lens is correctly positioned. Then they get sent back to the original High St shop for you to collect. As you can see, there are several places where things can go wrong.
What I would do (and have done) is to go back to where you got your glasses from and say that they are not giving you good clear vision and you want your money back. They will not want to do this (probably) and are likely to offer you a re-test. If they do, take it. They will do the second one more thoroughly and offer to put things right at no cost (and they will probably want to take the old prescription).
A thorough examination should spot several of the other optical conditions that could cause some of your symptoms – and trigger a referral to your GP asking for a referral on to an Ophthalmologist. One condition that needs immediate attention is Glaucoma because it cannot be reversed – only halted in its progression. This is one time when I have paid to ‘go private’, but Karen’s suggestion of a walk-in clinic is an fast alternative. If the vision problems came on really suddenly (say a few days) then it could well be down to a relapse, and the relapse could well have affected the optic nerves, so her suggestion of contacting your MS nurse for steroids is something you should do right away.
If your work as a CAD technician means that you spend a lot of time looking at a big monitor, and that is getting blurred, you could consider going into your nearest large Tesco, and sampling their reading glasses (they have a very good range). This is not as good as a proper eye-test, but it could be a quick fix.
So that comes back to the original question – what is your real problem? Is it just vision, or is it a nervous system problem? Either way, you need to get it fixed fast.
