Night-blindness Beta-carotene (vitamin A)

Recommended Posts

I've pasted the title in from an article I found on the net.

 

Over the past couple of years I've noticed my night vision has become quite bad. I have difficulty seeing things when it's dark and I refuse to drive at night due to this.

I'm sixty-one now and from what I've read it appears as not uncommon. My daytime vision is fine.

It was suggested that Beta-carotene (vitamin A) might help, although not a guarantee. I understand, but thought it was worth giving it a go.

 

Where can I find "Beta-carotene (vitamin A)"? Is it always in a multi-vitamin packet, or do I need to ask for it specifically?

 

Next question is - which shops? What national chains here might sell them? I've looked at the Boots website, but can't see anything. Watsons website also don't seem to list it either.

I'm in Udon Thani.

One small, raw carrot contains about 8,000 IU of vitamin A, which includes 4,000 μg of beta-carotene.  That's almost 300% of the recommended daily allowance of vitamin A, at a fraction of the cost of pills.  Plus you get other nutrients and fibre.

Thanks for the suggestion.

As an ignoramus to do with food and medicine, does it need to be a raw carrot, or can it be cooked, as part of a dish?

i.e. does it lose it's potential 'eyesight benefits' if not eaten raw?

Cooked us fine.
But Vitamin A is unlikely to help unless the problem is due to Vit A deficiency which is extremely unlikely.

Thanks.

Is there something else you might suggest to help with night-blindness, or is it probably only due to age?

I always understood the consumption of carrots to boost eyesight to be an "old wives' tail", something made up during WWII to cover up a night vision secret.

However, I Googled a bit and now I see something that contradicts that belief.

 

"Carrots do have medical value. They contain beta-carotene, which the body converts into vitamin A. Vitamin A is good for healthy eyesight. It helps the eye convert light into a signal that can be transmitted to the brain, allow people to see in low light, according to Scientific American"

 

Sheryl would know far better than me but it is my understanding that cooking carrots (and other vegetables) reduces the vitamin value.

Great topic this. Age comes along no matter what we do.

 

Try the figure-of-eight bluesofa.

 

Just close your eyes and roll the eyes around in a figure of eight movement. Can be done with the eyes open, but better closed. Repeat three times. Don't over-do it as it can lead to bad headaches. But, once a day is good.

That was the same conclusion I came to.

As I said in my OP was how I came to paste the thread title, having read some articles about it.

Yes, I'm hoping Sheryl might have some other suggestions.

Head straight to your nearest place that stocks "King Project" fruit juice cartons...

 

GAC juice has that vitamin through the roof and they have it all year for sale I think...It is a spiky orange fruit on the carton...20 baht...no preservatives/additives either.....great line of juice all-round.

 

My eyesight is actually better now that 20 years ago day-time anyway...strange !

 

This carton....

Thanks, although reading it seems to suggest there may be many other reasons for night-blindness having appeared recently, rather than just impending old-age which I initially assumed, as others of the same age I've spoken to seem to have the same problem.

In an older person glaucoma and cataracts are common causes.

Get a full eye check up. Should do that periodically anyhow when past a certain age.

OK. Do I need to ask for anything special?

About a year ago I had a new pair of glasses, but it does make me wonder if the onus is on me to be 'asking the right questions'?

No one mentioned anything, but there again I didn't ask.

 

Should I be specifically asking about 'glaucoma and cataracts' here, or will that be checked automatically, wherever I have my eyes tested?
