eye sight improvement?

has anyone else noticed an eyesight improvement over time? I’m 49 and thought reading glasses were now part of my life (currently +1.5 assessed by spec savers) but I am not always needing them now 🤷🏽‍♀️ only for teeny tiny writing or when tired 🥱

Is that anT3 /vits benefit?

Or is it in my head 🙄

I wish!! I've been about -6 (severely shortsighted) since my mid teens. Now fast approaching the need for varifocals. 🤓I wish I could believe optimising my thyroid and vitamins could help but I won't hold my breath 🧐

Hi l might have some good news for you. My husband is short sighted not too badly. He needed glasses for distance but can read small print ok. Since his 50s his eyesight has improved hes in his 60s now He wears glasses for driving distance only now. He was told his prescription is lower because as you age if you are short sighted you can get the typical age related problems the long sighted people get they usually need reading glasses as they age but if short sighted this ageing condition can counteract your short sighted vision to become better than it was.

His sight is definitely better than before. I'm long sighted so l need glasses now but didn't before about 45

Well, if that happens to me it'd be an absolute miracle! Fingers crossed 🤞😂

Not for me unfortunately. Had my eyes tested after a few years gap a few weeks ago and needed a new, stronger prescription.

is that for reading or driving or ? Just curious 🧐

I think distance/driving was quite a bit worse and reading a little worse. I switched to varifocals a few years ago because juggling pairs of glasses was getting to be a nuisance. 😆

I find T3 has made my vision a little brighter / sharper. Dr Skinner observed that some hypothyroid patients had floaters that resolved once they were treated. He could also spot elevated cholesterol in the eyes of some patients.

Never even thought of it as an additional benefit, but, yes, since taking T3 I also have fewer floaters. I'll put that on my list of improvements caused by T3. Thanks :)

Wow, just realized I have markedly less floaters.

Maybe you do have fewer floaters.

But beware that being hypothyroid can impair the processing in your brain which helps to cope with floaters. The way we see well despite having floaters.

Dr Google says: Apparently, the fluid levels in your eyes can help you see more clearly at times but improved vision through ageing is not necessarily positive, it can be a sign of diabetes developing or early cataract development. I guess an eye check would pick up the latter but may not pick up the former.

RegenallotmentAmbassador in reply tocaledoniancat

ah no but thanks for raising that, my eyesight definitely isn’t improving with age I’ve had the eyes of an eagle until about 12 months ago started to realise I couldn’t read ingredients on small labels etc. distance vision is still great. But will keep testing regularly 👍

According to my optician, it's 'not possible' to improve eyesight as an adult. I've been on T3 only for a few years now but my eyesight continues to decline (I'm in my late 60s). I think I may have fewer floaters though.

TSH110 profile image
TSH110 in reply toTitaniumfox

Your optician is talking rot! Mine improved immeasurably once I took T3.- as if your eyes are unrelated to the general state of your health! They’ve got a blood supply so improvements must be possible even if they are not guaranteed. No doubt it is difficult to stop some causes of deterioration. I used to do a lot of eye exercises that helped but mine are on a gradual decline now. I might start taking iron again given some comments here.

Yeah, I do take so-called educated medical peoples' advice with a bucket load of salt. Still I am an old bird so not expecting miracles. However as someone mentioned floaters I do notice a reduction now.

TSH110 in reply toTitaniumfox

I’ve never had those floaters so that’s a small mercy I’m grateful for. Yes I’ve got through a few buckets of salt over the years 🤣🤣🤣

my eyesight just kind of became clearer. As if I was suddenly watching the world in HD rather than analogue TV. Everything was sharper, even colours.

Funny you should say that as I went for an eye test yesterday and no change to my prescription and some of the tests he said were good so its a thumbs up for T3.

lucky you 🍀👍🏽👍🏽👍🏽☘️ 👓▶️ 🗑️

I think some eye conditions can improve over time you must have one of those. T3 has helped me in many ways but my eyesight continues to deteriorate but I’m sure it would be even worse without NDT it was virtually shades of mud on Levothyroxine

Most of the discussion has focussed (sorry :-( ) on the lens and literal focussing.

But hypothyroidism can affect our sight in many ways:

Impaired colour perception - to the point of seeming black and white.

Impaired sensitivity such that in low light levels, sight deteriorates severely.

Impaired tolerance of changes in light level such as oncoming headlamps.

Impaired muscular control over the whole eye and focussing.

In severe cases, the optical chiasm ( en.wikipedia.org/wiki/Optic... ) can be affected by an enlarged pituitary eventually which can have a profound effect on vision.

Impaired processing of vision including reduction in depth perception (which I describe flippantly as 2.5 D depth perception).

On top of everything else, slowed brain processing can impair higher-order aspects of visual perception such as recognising what we see.

Opticians might have gone through quite a bit of training and come across some of this as theoretical aspects of vision. But they simply won't appreciate how hypothyroidism impacts on vision at every level and in ways their eye tests cannot detect. Not even specialist ophthalmology consultants will appreciate all the effects, nor will they have the technology to measure them.

In case all this reads as profoundly negative, the positive is that it is often possible to achieve major recovery when adequately treated.

I find I'm no longer sensitive to bright sunlight as I was 2 years ago, now I'm on T3 only. My eyes used to water a lot outside in the sunshine and it was very uncomfortable. I noticed last summer (and that was a hot and bright one indeed) that I was no longer having that problem.

My left eye waters really badly outside - especially in sun and wind. I have tears streaming down my face and I can’t see through the tears. Dry eye treatments did not help. I’m on Levo monotherapy.

I get very dry eyes quite often, really sore and achy. Fortunately I am prescribed Carbomer lubricating gel and that does the trick. I always wear sunglasses in any kind of sun as I have a cataract and blue eyes. I had one cataract removed a few years ago privately, but they refused to do the other one as, apparently, I had a detached retina at some time in the long distant past (news to me!) so they said the NHS would need to do it when it is bad enough (I won’t hold my breath!). Try the Carbomer, it really is soothing (don’t know what it will cost, though). Good luck.

sounds good, I’ll see if I can get some. I’m a bit hayfever ish and get runny eyes.

I had a definite eyesight change for the better with NDT (none with Synthroid). There was no other change with diet or supplements. I suddenly realized I was reading without glasses.

It made me wonder if it was to do with T1 or T2 . Why? Unfortunately I had some border issues and had to leave NDT ,& go to Synthroid/Cytomel and I felt a bit of a drop. But am still reading without readers and that never happened on the phone before.

(And of course many on here are reporting a change without being on NDT)

helvella profile image
helvellaAdministrator in reply toLitatamon

It's fine to consider what T2 and T1 do, but whether we can get a meaningful amount in desiccated thyroid, that can then get absorbed and end up in our cells, is very much an open question. Not aware of anything that shows it can happen.

Litatamon profile image
Litatamon in reply tohelvella

Maybe I am not getting as high of an amount of T3 ( via Cytomel) as I was in the NDT dosage. And that has produced the decrease. Either way I am grateful not to have to grab glasses every time with the phone now.

Last summer when I was on 60mcg T3only, I noticed a big improvement in my eyesight and this was borne out by needing a lower prescription for distance. Sadly Endo reduced my T3 and been messing with doses and I am back to where I was and particularly struggle with focus.
