WHAT is NIGHT BLINDNESS? | Optometrist Explains

Night blindness is a concern many people have in the clinic, today we cover different aspects that can worsen vision in the dark.

It can also mimic night myopia and vitamin A deficiency

This is not true blindness as total blindness is when there is no light perception

GEAR I use:

Camera:
Lens:
Light:
Soft box:

Im night blind. My pupils are naturally wide so it lets in too much light which makes things look brighter during the day and darker at night. It gets painful during the day sometimes

I personally search for hours and hours to find a understanding and entertaining video but all the videos are about tests and exams which i find very annoying. So thank you sooo much man i look forward for more videos

[GarikDuvall]

For me I can see OK at night when there is limited lighting. However, when driving, car lights really mess up my vision... I believe more than the average person. Not sure what the cause of that is, or what to do about it. I am slightly nearsighted, but eye examines have not found any astigmatisms.

Honest question that sounds like a joke:
How can one tell the difference between night blindness, and nearly every car now has LED ultra mega bright headlights blindness?

[ArmchairAthlete]

@AntoniotheOptometrist this is also caused by refractive surgery like LASIK thanks to the small, permanent optical zone it creates in your cornea. Would love to see a video on that and the other problems with these surgeries. Except halos don't just appear around things that emit lights like streetlights, they appear around *any* bright colored object/character/UI elements/text against dark backgrounds in low light.

I have a long commute (over an hour) and I have noticed that my night blindness gets worse the longer I drive. Some nights are worse than others. I used to think it was just dependent on if my eyes were dry or not, and how tired I was driving home, but now I'm wondering if any of it may have to do with the moon cycle. In theory if its a clear night with a full moon, there should be more natural light at night and so your pupil will not expand as much, so maybe you will have better vision?

I have problem when I seat where there is bright light my vision goes dim slowly

[injaehwang]

For me and most of the people. I have visual snow syndrome only the night

[its_lucky]

My eyes take a long time to adjust to limited light but it’s something I’ve had to live with. But now at night I see double stars (when there’s only one there). Is this a processing problem?

[InvisibleRen]

I always struggle with my phone because the brightness hurts my eyes and triggers migraines easily, but if it’s too low I can’t read well, but if I keep the brightness low and increase the contrast, the white hurts my eyes bad. 🤦🏾 So yeah, that’s why I listen to audiobooks and why I just guess what’s happening to characters in the dark as I read subtitles on a foreign horror Netflix show. 😅 and if I’m on YouTube comments or email, I suppose I’m just making my vision worse but I just haven’t found a solution.

[GEE-SHOCK]

Thank you! As someone who always experience difficulty in seeing clearly at night, I have recently got a pair of Zeiss SmartLife Digital lenses and the night vision is significantly improved! I can feel the contrast is so much better as the lenses were designed according to the pupil size of my age group. Nowadays well designed lenses can really help our night vision !!

[paulsmith]

If I turn off the lights just before sleep in my bed room so it's dark, my left eye has like a smokey or foggy curtain veil blocking the centre of my vision for a min untill my eye has adjusted to the dark its weird and worrying :(

[RedDeadSakharine]

Oh my Lord, I've been wondering all my life, why lights in the dark have halos. This was eye-opening! (heh)

[readingwithfrenchy]

I thought it would be interesting to add to this with my eye condition. What i have creates night blindness to the point im not allowed to drive at night anymore, its so newly discovered it doesnt even jave a name yet besides what its described as how it looks, and it gives me the same symptoms as macular degeneration and macular pucker without actually having either. I have a misshapen macula and it got so bad recently i got my ADA to not drive at night anymore as all i saw was black everywhere unless i had extreme amounts of light where it represented day time. Im being experimented on by my eye dr and the NIH (USA) to see what changes this or at least my symptoms. Macuhealth has actually gotten me from 20/60 to 20/25 in a few months. Macula is still rectangular but i can see drastically better during the day and almost 100% at night again.

[Hrochnick]

I struggle to read menu's and the like in bars and dimply lit restaurant's, even when wearing my glasses, when all my friends have no issues (even those with glasses). When I switch on the torch on my phone, bingo, it's nice and clear (and all my friends laugh at me :) ). Is this a sign of night blindness?

[CherylHuse]

I am struggling with this and also static in my vision. Doctors haven’t been able to help me. I’m afraid and would love some inspiration on how to fix this. I’m a bit low on Vitamin A which is a test I paid for to try to help me figure out some more. Please let me know your thoughts! Thank you so much!

Put an LED strip light inside your bag with some organizer to solve your problems for buying a new bag for ease of use.
