There's a lot of misconceptions around how we get bags under our eyes. I always assume it's their stress and they haven't been sleeping.
So I did research to look into this, and a lot of people don't know this, but it's actually...
Really?
Mm-hmm.
So if I never wanna get bags under my eyes again, what is the natural, easy solution?
Try this. Dr. Joseph Allen is the board certified eye doctor-
Helping millions of people understand eye health and unlocking the secrets behind achieving sharper and healthier vision. I really wanna talk to you about your many misconceptions because I don't know what's true.
Sure.
Okay, so my vision loss, being inevitable, is that true?
Unfortunately, there are changes that occur with age that will change your eyesight and vision. But there's a lot of things that can help prevent and slow down progression, and we'll go into them.
And then every once in a while, my eyelid starts twitching. What is that?
Eyelid myokymia. So that is your threshold of your stress. Get more sleep and stop drinking so much caffeine.
What about blue light? Is that harmful?
The blue light that comes from your digital screens has consistently shown in research to not increase the risk of aging eye diseases. And research on using blue light glasses shows that it could just be placebo effect, but if you're worried about how blue light's affecting you, just moving your phone back twice as far will decrease your blue light exposure by 75%.
And more people are starting to care about their eye health than ever before, but is our eye health getting better or worse?
Worse. For example, right now about 30% of the world's population is nearsighted. But by about 2050, we will have about 50% being nearsighted because of our lifestyle.

I am a doctor of optometry. I am a fellow of the American Academy of Optometry and I'm a diplomat of the American Board of Optometry. So I practice eye care here in the US and I, I see patients for all sorts of eye conditions, whether that be diagnosing, managing anything from vision problems simply as like nearsightedness or astigmatism to fitting contact lenses, to diagnosing different diseases in the back of the eye, and then prescribing medications or therapy to try and prevent that from getting worse or to help treat it. On top of all of this, uh, I also host various, on, on various social media channels, a educational website about helping people learn about the eyes, their vision, and finding the best vision products. And that really falls back to my mission of just helping people see their very best today, but also keeping them see their best tomorrow.
