Why is modern eyesight so bad? - Is the eye care industry a scam?

[Meiwaku]

where did the genes for bad eye sight and narrow vaginal canals come from? After 100,000 years of natural selection they still weren't eliminated? Or is it like Palpatine in the new Star Wars movie?

Natural selection basically takes non-reproductive conducive genes. Certain things that don't really matter to reproductive success are not counted.

It's basically why people have body variances and differences in things that are non-life threatening or to where they can still reproduce.

For example some women have a tilted uterus, this can make conception more difficult but it doesn't mean it's impossible, so therefore it has not been selected out.

Even very debilitating things like certain mental illnesses like schizophrenia doesn't mean that you can't have sex and have a baby, even if you might be better off not doing that....

However there's no adult people with hydrocephaly who are reproducing with that Gene. Or certain other retardations or sexual disordera where it's literally impossible. It's a dead end on the line.

If they can't reproduce, how did their parents reproduce? Where did the hydrocephaly allele come from?

 

[Johan Schmidt]

If they can't reproduce, how did their parents reproduce? Where did the hydrocephaly allele come from?

From damaged genes, typically caused during the early stages of development, from a wide variety of causes. Sometimes the X chromosome can become malformed; which leads to a variety of problems. Or it can be through simple mutation that isn't lethal to the embryo early on in development.

As for alleles for eyesight. It's rare that a single, or even small cluster of alleles will be directly causative of one distinct condition. Most traits are affected by the interplay of multiple genes, which are themselves impacted by the expression of other multiple genes. For example, I worked on the expression of a gene called TCL1a; which was found to be linked to FTD in humans. The way it's linked is because its expression can act as a regulator of another genes; one of which was AKT2. The AKT2 gene was downregulated, which caused an impact of SH3RF1, which (in the brain anyway) regulates the structure of neuron cell membranes. The problem with directly altering AKT2 though, is that increasing expression, disregulates more genes which are linked to everything from diabetes, to breast cancer.

Anything that happens in your body that isn't something quite literally ripping holes into you, is genetic in function or origin. Because the expression of genes is regulated by, and regulates every part of the body. A decrease in eyesight is probably genetic, either directly by the circulation of alleles that are more likely to express a certain phenotype (remember, your eyes aren't just 'bad' it's various muscles, nerves and lenses that are becoming misaligned) that is structurally unsound; or through the circulation of alleles that allow for the conditions we live in, to more easily degrade our eyesight.

But I am a geneticist, and thus I think everything is genetic lol.

Without full eyesight someone wouldn't be able to fight efficiently; hunt properly; gather well; do much outside of the gifts offered by civilisations enabling them to do.

Because natural selection no longer applies to humans -- certain abnormalities are increasing such as bad eyesight. In nature the gene responsible for this wouldn't be able to spread.

Eyesight came up in conversation today and a fat autistic guy with a really abrasive attack to the way he speaks asked(rhetorically) "Why is it that my grand parents had good eyesight but the younger generations in my family have to wear glasses."

I explained it to him in a way similar to your post and he shut up lmao.

I don't like him much at all.

Glad I could help lol

The stereotype of glasses wearers being nerds/intellectuals is alleged to come from reading late at night damaging their eyesight.

That said, it seems more plausible to me that people who read would be the ones that actually wore glasses to begin with.

I saw this while scrolling on mobile, so I didn't get to say how enlightening this post was. I just wanted to say thank you for revealing to everyone on this thread the truth about myopia and glasses. I have been using the reduced lens method for roughly a month and a half, and the changes have been staggering! I have gone down my at least .50 diopters, and I am now at -1 diopter for each eye! Keep up with the good work!

I always thought it was natural selection just not selecting out poor eyesight genes but then I heard about that girl who was locked in a room for her whole childhood and could only really focus on things the distance of the opposite wall of the room away. They also did studies on animals where they put baby animals in a box that only had horizontal lines on it. Then after they grew up they released them and they'd walk into table legs because they couldn't see vertical lines (I'm probably getting this mixed up. I'm going by memory). So in childhood your brain learns to interpret visual stimulus and your eyes and brain adjust to it. So you can have eye problems because of it. So I'm guessing kids only focusing on things directly infront of them makes it harder later in life to see things at different distances

This is my uneducated guess, but, having had issues with my thyroid and hormone imbalances as a result, I do know that eyesight can actually be impacted by your endocrine system pretty hard. With the presence of xenoestrogens and microplastics, that could be a component of it.

I've been legally blind without glasses since high school)

If it's legal, what's the problem?

How far can you take this? I can see this working if your vision is 1-2, but I think 3< you'd be blind even in ancient times.

To be quite frank, it goes as far as you push it. There have been many cases of people with -5 diopters in both eyes making a full recovery after years of the method working for them. I even know of -10 + diopters making sure but steady progress. I would love to DM you about this if you would let me. There's a lot to discuss here in regard to personal health and how it might affect improving your eyesight. Please shoot me a Dm whenever you're ready to talk! Stay Holy!!!✞

Personally, both my parents had eye issues yet I ended up with 20/20 vision. I guess I was outside a lot as a kid, but I also was on my PC alot too, so I couldn't tell you.

I think we're a statistical anomaly. My parents eyes are fucked, my father is legally blind, yet I spend all day on my computer (as much as I could since I was about 11, still went outside like crazy though) and my vision is pretty much perfect. Last test scored about a 20/6 which apparently is exceptional (still have the score card in a box somewhere lol).

Combination of genetics and environment (nature 'n' nurture).

I mean I guess so. Some of its genetics, some of it is luck

Personally I think the abundance of led lighting has something to do with it. Leds are everywhere these days and they're a lot brighter than most people realize. Even with lens covers. Even most screens these days are actually leds.

They changed the lighting at one of my old jobs. It was a shop in a big warehouse with high ceilings so the lights were pretty high up. We had just the regular fluorescent tube lights. After they changed the lights a few of my coworkers were complaining about their eyes hurting and having headaches for a few weeks after. It turns out they switched the lights with leds that look like those fluorescent tube lights.

I've never really liked led lights. I don't like the light they put out. They make my eyes hurt. The light just always seems kind of unnatural. Even the yellowy coloured ones don't look right. I went camping not long ago and I had both an led lantern with me and a coleman white gas lantern. The led one is pretty bright, it puts out a yellowy white light. I didn't really end up using it at all.

The coleman lantern though I used every single night for hours and that $18 I spent in gas to run it was worth every penny. The light it puts out just immediately makes the campsite feel comfy and nice. Especially during a fireban when all you can get away with is throwing some sticks on a portable charcoal grill. That warm, soft light, that wasn't actually quite as bright as the led, made hanging out in the dark much nicer. The led lantern made everything all eerie and weird looking and i'm definitely glad it was not my only source of light.

I recently watched a video about electromagnetic radiation, and the guy that was being interviewed mentioned LED lights at some point. He said they deplete melatonin in our skin, making them carcinogenic. I haven't investigated further into this, but I wouldn't be surprised. There's been a huge push everywhere to make people change from halogen light bulbs to LEDs on the basis that they're supposedly more environmentally friendly. Given all the lengths that state-nations go in order to poison their own people in every imaginable way, I wouldn't be surprised at all if LEDs are actually terrible for us. I recently bought a ton of halogen light bulbs, since they're being produced less and less and are becoming more scarce. They consume a lot more electricity, but they're so much nicer to the eyes, so much warmer. (In my opinion, at least.)
I have an LED in my bathroom apartment, and it's the coldest, most nastiest, bright thing you could fathom. I hate that thing, but I need to hire an electrician to remove it, since it's installed directly in the ceiling. It reminds me of this song:

Also, something I haven't seen mentioned here thus far, is the fact that a lot of emotional wounds provoke physical ailments related to that particular emotional trauma. The one for myopia, if I recall correctly, was an unwillingness to see a painful reality. So the body literally shielding you from a painful situation you can't escape. I don't know if this resonates with anyone but I have myopia and have had it since around 10, I think, and I can definitely see that in myself.

This is from a "bio-emotional dictionary" I have, it's in Spanish, though:

I also haven't seen anyone mention the fact that glasses, the thing that we use to "correct" bad eyesight, are the very thing that perpetuates the problem. They're a band-aid solution that only makes things worse over time.

Is it a pot light? It should just pop out. Somewhere nearby in the ceiling you'll find the driver box with the feed from the house going to it. Disconnect the wires, make sure the breaker is turned off before you disconnect them, get a round easy box from the hardware store. It's an electrical box designed to lock into drywall. Then get one of those cheapo lighting sconces, shove the 120v wire into the easy box with a connector, secure the box, wire up the sconce, screw it into the box and you're done. It's an easy job you can do in about 15 minutes to a half hour, an electrician will charge you a few hundred for it.

Thank you very much for your detailed instructions Although there's no box of any kind on the walls or on the ceiling

Where is the main wire going into? That's all you need is the 14/2 or whatever wire it is going into the led light.
