I changed a lot of glasses until one specialist recommended me wearing glasses with astigmatism lenses, and it was the real solution, it made glasses so much more comfortable. It's shocking that doctors ignored my astigmatism and just prescribed me usual glasses.

usually doctor won't ignore astigmatism, but on the smaller scale, they would recommend not to prescribe astigmatism lenses, because it might just be uncomfortable to wear (this happened to me, I told my doctor to prescribe the lenses anyway despite his previous notes), but when the astigmatism scale rises, the doctor will prescribe the necessary astigmatism lenses and this times it's actually helped a lot

that's actually quite wild. all of my glasses have astigmatism lenses, well except my first 2 pairs. Actually the very first thing clinics checks is if you have astigmatism, and then they'll move on and check the grade. the ones who made your early glasses must be ripping you off because they literally skip the checkup

Damn, need to check my glasses for that

The orientation of the lens would actually not change the way its focusing light! These lenses have a negative optical power, which is what you would need if you are near sighted

🤣 Light works differently for everyone, apparently

I feel represented. I hate driving at night with foggy weather even with my glasses on.

As someone with astigmatism, glasses definitely don't prevent the lines from lights in the dark.

Astigmatism at least my one also effected how colors looked, when i put my glasses on colors were more vibrant but its probable just them having sharp edges and not somewhat blured borders

This video has taught me optometrists dont always tell everyone enough huh

Suffered 3 long weeks from constant motion sickness. Went to my friend's optometrist as he suggested and was diagnosed with astigmatism. Now I'm wearing glasses and have been well since then. :)))

That lens corrected for astigmatism and myopia If it was a "pure" astigmatism lens it would've been more noticeable Like a -4.00 +400 the higher the power the most noticeable would be in the demonstration

I got +8.25 for astigmatism.... Nice to know that that strength would have made a great model!

The think I payed attention to the most, is the fact that there's a way to deal with astigmatism

What other topics would you like us to talk about?

You should have held the lenses in reverse so you could show how the light focused to the eyes

Bro I literally just got new glasses for this today and I think they are the glasses you held up in the beginning

i have horizontal and vertical astigmatism and even some diagonal light streaks when is realy dark

i need astigmatism glasses its so hard to drive at night because of those lines

I wear astigmatism corrected glasses. Seeing clearly is especially important for me when riding a bicycle at night.

“Eyeglasses” XD where else would you put them?

i want to make laser box like that ..can u help me @@edmundoptics

I have severe myopia/nearsightedness and pretty bad astigmatism. I wear contacts, which don't help my astigmatism much, but they're a lot better than glasses. Glasses always make my astigmatism worse, and cause really annoying color abberation, a red/yellow and blue/green glow on anything that contrasts with the background

That Trailer Park boy is gonna be pissed when he finds out you stole his lenses.

Making a toroidal mirror for a Yolo is fun.

Graphic. Thanks.

seriously the demo would have worked better if the lens was pointing the other way round so you can see the converging lines better pointed away. why do you need the converging lines pointing to self?

That's also why doctors ask if you have cylindrical lenses. Cylindrical lenses have the correction for astigmatism

Kindly sent the manufacturer's link to purchase those gadgets

I have nearsightedness and astigmatism and it's not so severe that I always thought what I see is normal but when I got one everything is just so much more clear. Apparently seeing things like you just finished crying is not normal.

I NEED THOSE GLASSES (ASTIGMATISM) NOW

Sounds like nile red

I have mild astigmatism and recently bought glasses(with the correct prescription), but i get the 'shadow' effect on certain things, like when looking down or up towards a piece of paper with text on it i get the shadow effect on letters. Is it possible to get rid of this shadow-effect entirely or is it supposed to be that way? Anything i can do to minimize it (like thinner glasses?). When i look straight at something its fine.

Got the PRK surgery this year after 9 yrs of wearing glasses, really much more convenient and now I don't have to change glasses every few years. It seemed like opening my eyes to a new world again and I got this sense of "freedom"

do they work when i don't have lasers for eyes?

Exactly how nearsighted was the person who's glasses you used?

How does that work with contacts for astigmatism? It's not like I clock them in the correct orientation.

@edmundoptics

5 ай бұрын

Actually, you can! Contacts for astigmatism are curved differently in different directions. There are usually marks indicating which part should be on the bottom, but the bottom of them is made heavier so that if you put them in, you can blink for a few seconds and they should settle into the proper orientation

I desperately need glasses that correct my astigmatism. I'm just about to get my learners permit, and driving to school in the morning is gonna be a nightmare

At first all doctors just tells me that i have only -0.25 and -0.5 but still things was too blurry, my friends with -4 sees better than me Glasses with astigmatism lenses is such a nice thing

I do not knew that the light comes on back of lenses

IF only the lens had been correctly faced in the lasers

I think I didn't have the glasses for astigmatism because I could still see the bright light when driving at night

Recently i get to know that i have astigmatism, all my life i though that it's normal way to see lights...

By the way, what does blue filter do? Can someone explain pls...

damn i wear glasses with lens for astigmatism for ages and i never noticed the difference

i’m also thinner on some parts and fatter on others

I expected scary screaming face appearing at screen in last seconds

Hadn't heard the term "astigmatism" before. Am I understanding correctly that it's different to near-/far-sightedness? Near-/far-sightedness I understand as the eyeball itself (and thus the position of the retina) being different while astigmatism affects the cornea?

@edmundoptics

5 ай бұрын

Yes, astigmatism has to do with your eye being asymmetrical, so it could be near-or farsighted in one direction while having perfect vision in the other

You’re telling me I can turn star mode off

Bro please use a nice mic

I didn't know that! And I have an astigmatism. ( it appears more of a star like shape * * * )

I have a stigmatism... Never liked glasses so intried contacts... Issues are they are weighted since they have to stay oriented a certain way... They just never worked properly trying 3 different brands.

Either my glasses are close enough to my what I need or they don't account for astigmatism

That's would be amazing to see with my proper eyes, but i see a photo of a night city and i surprised by the look of cars lights, personally i prefer the glow around lights cause it looks like tiny stars and FEEL brighter. Still i going to buy that type of glasses to see the world like everyone do.

Wait i can get glasses for my astigmatism never knew

Constructive feedback: 1. I imagine it would be nicer to have more beams to fully see what is happening. 2. I'm not sure how many non-native English speakers know the term "astigmatism". In this case you kind of explained, but maybe a definition on the screen would be nice :)

I have both astigmatism and myopia and at night if I don’t have my glasses it’s a disaster😅

@edmundoptics

5 ай бұрын

Definitely talk to your eye doctor about them!

Why would you use a lens on an array of lasers to demonstrate how that lens disperses light? Shouldn’t you flip it around to show how it focuses it in the same way that it would focus rays of light onto your pupil (and by extension, retina)?

Glasses. Just glasses. 💀

i guess the laser box here is not good for showing the astigmatism lenses effect. a 2d laser array or cross line laseres procection on a surface would be better here.

People in physics class:🗿 Also, people when saw the same theme in shorts: 😮

I have astigmatism because both my parents have 'em Thankfully I have like 3 astigmatism corrected glasses just for my personal use-

I have stigmatisms in both my eyes, I see stars lol

Eyeglasses. As apposed to foot glasses?

Wait is that what that’s called? I never knew that

Theres are EYEglasses, not to be confused with regular glasses that you can wear anywhere.

does anybody know if this corrects for astigmatism
