Hi,
Do you have such a symptom? When i need to get out and if it s sunny i can not without sunglasses. I feel like i am getting dizzy if i do not protect my eyes. And i do experience this since March and that was the time when i first checked my thyroid.
Yes, I have light sensitivity, which includes reflected light being a trigger for migraines (which thankfully are normally only the visual disturbance when triggered by light, rather than the oppressive headache that I used to get through stress). I have never linked the light sensitivity and migraines with my hypothyroidism though. Mine started after I had eye surgery, inserting intra-ocular lenses beneath my natural lenses and then fixing astigmatism using laser surgery. I intentionally had one eye set for long distance and one set for short distance, which does make the brain work harder, effectively having to rewire itself I guess. Because of the timing of my light sensitivity and migraines starting, I have always linked it to the eye surgery, but as I was already hypothyroidal by then, I guess it is possible that it may actually be somehow thyroid-related. I have found no evidence, not even anecdotal references, of eye surgery causing the problem, so perhaps it is thyroid-related. I don't know. I haven't noticed it becoming less of a problem since switching from T4 to NDT, although it's still early days, so it's anyone's guess I'm afraid. Sorry to not be more definitive.
I went also to the doc, my eyes are ok. Well i do have problems cuz i do not see far away and i do wear glasses, but nothing else is wrong. She suggested me to get more sleep, to use not so often my phone and gave me some eye drops cuz my eye is dry and some vitamins.
Hi
Yes, I'm sensitive to both artificial and daylight. Also highly sensitive to sound and general over-reactivity to movement IE scooters, cyclists moving on pavements etc...
Make me jumpy! I have seen some of the American thyroidologists mention this with the thyroid /adrenal connection.
My wife gets migraines when shifting into bright light ,but is not hypo.
I think you should visit an optician for advice.
Yes !!! I went to the opticians and I now have a tint on my lenses for this very reason.. I don’t know why it happened but it just has x
Hi Oanav,
Me too, usually when im undermedicated and this put a strain on my adrenal glands which gives me sensitivity to lights and sunlight. The days when ive had good sleep,therefore better absorbtion of thyroid meds and therefore better absorbtion of supplements everything is considerably better regarding light or heat sensitivity.
Every best wish G.
You may have vitamin A deficiency. From this link (my emphasis) :
thyroiduk.org.uk/tuk/treatm...
Vitamin A (not carotene)
Carotene is a precursor of Vitamin A. An underactive thyroid gland cannot efficiently convert carotene to usable Vitamin A so however many carrots etc. you eat, it won't help. Vitamin A must also be accompanied by protein to make it available to the body, so if you are on a low protein diet, you may be deficient in this vitamin. If you are low on Vitamin A, your ability to produce TSH is limited. This vitamin is required by the body to convert T4 to T3. If you find that lights are too bright or night driving is a problem, try taking Vitamin A supplements along with more protein and see if it helps.
Beta carotene is often sold as "vitamin A". But it isn't vitamin A, it is prohormone vitamin A. It needs conversion to be usable as vitamin A - and as the paragraph above says - people with hypothyroidism can't do the conversion very efficiently, so you need to supplement with "real" vitamin A which includes retinol, retinal, and retinoic acid forms.
A food alternative, if you are a meat or fish eater, is regular intake of animal liver or fish liver oil which has the highest concentration of real vitamin A in any food.
