ANY OPTICIANS AROUND

[ByThePowerOfGreyskull]

Had my eye test today and I need glasses but can't remember what he said was wrong with my eyes.

My long sight and short sight are both very good, but the vertical OXO test lines showed there was a problem - a SOMETHING excess. but I can't remember what the "something" is.

DH will want to know why I am paying £85 for glasses if I am neither short nor long sighted.

Thanks

not an optician, but know what the OXO thing does. It checks how your eyes work together - so the vertical ones not lining up shows that your eyes don't move left/right equally. Ie a slight squint.

You might not notice this if its only slight, but it is much more fatiguing for your eyes to try and keep your vision correct if there is an imbalance in the muscles, so you might find you get headaches when working on the PC or reading for a long time

thanks cmotdibbler. He never said the "Squint" word, was he cushioning me from it?

I think that as people only think of a squint as the visible thing of your eyes not pointing the same wasy they don't tend to use it in adults

OOOooooh Nooo I have a squint??

I have a massive one, and had two lots of surgery and now have a lot of prisms in my glasses to deal with it. And you'd never know by looking at me.

I know from bitter experience how much difference it makes getting the prisms exactly right tho - you feel so much better for it

Let your Dh know your eyes need some help in working together properly.

The markers moving are usually decompensated heterophoria which is a bit different to a squint.This can cause headaches,aching eyes,blurred vision.

Prism is what is used to align the markers during the test.

For the difference between squint and heterophoria you need a cover test.If one eye is covered in a squint the other squinting eye then moves in or out to take up fixation (because the other eye is already in a different position i.e squint which is usually visible to others at least some of the time).
In a heterophoria it is the eye under the cover moves and you can see a movement back when you take the cover away ( it is latent, you can't see a heterophoria looking at someone).

Just to confuse things though sometimes a decompensated heterophoria can break down into a squint.

What does your prescription say - has it got prism in?

OOh I am not sure I ordered the glasses there and they kept the paperwork,

Thanks for such a comprehensive answer Sonnets,

do you know what the Something word would have been?

Either a divergence or convergence excess?

Divergence excess

The term divergence excess (DE) describes a decompensated exophoria for distance, with any exophoria at near being of less amplitude and well compensated.

Convergence excess

Convergence excess (CE) describes a decompensated esophoria at near with any esophoria for distance being of less amplitude and well compensated.

Convergence excess!!! that was it Brilliant thank you soooo much
