Night blindness

[Guest guest]

My husband and I have just driven nearly 200 miles and arrived at our

destination in the dark. I noticed a big change in my night blindness during

the journey. For years I havn't driven at night (I didn't tonight either)

because my eyesight is so poor on unlit country lanes or an unlit motorway. I'm

so bad it feels as though I'm driving into total blackness so I don't do it.

Tonight, however, I could see much further and also my focussing was much

quicker. When I look up from map reading it normally takes me a few seconds to

gauge the distance of the vehicle in front.

Is night blindness a symptom/sign of hypothyroidism? I'm on 25 mg (low I know

but just beginning) of levothyroxine and have been for two months. I'm due to

see endo soon so should get it upped. I'm wondering if the levothyroxine could

have improved my night vision.

Ps. Could have been the snow all around!! Lol.

Hi Jane

Could be - vitamin A deficiency is linked to night blindness.

hypothyroid people have problems converting beta carotene to Vitamin A

So if you're taking meds to correct hypothyroidism, perhaps it's helping with

vitamin A? I don't know if nightblindness is a symptom of hypthyroidism in

it's own right (it wouldn't surprise me if it was)...i expect the snow helped a

little?
