So I was listening to Andrew Huberman's podcast. They talked about daily Cialis. Said that Cialis affects the smooth muscles, like the ciliary muscles in the eyes.

So I thought, as my eyes cramp and get blooshot when viewing flickering lights, that maybe I should try daily Cialis, whether it could prevent my eyes from spasming and getting bloodshot with flickering displays.

Lo and behold - now after 3 weeks, I can confirm that I can stare at my OLED phone screen until the battery is dead during the day and my eyes don't get bloodshot. It definitely helps.

Obviously, I need to verify this over months and different displays, but with the phone, the effect is clear.

I urge others who get irritated red eyes to try this. Cialis / Tadalafil is beneficial for many other issues as well.

Interesting link. As a heads up it can other adverse long term effects on vision, sp do research it properly. Would be interesting if others saw the same link. Do note that the blood supply to the eyes can also be increased by it, as smooth muscles are used for vasoconstriction. Which can affect both the eyes and other brain areas used for visual processing. As an stupid oversimplification of migraine, constricting blood vessels gives aura, and expanded blood vessels gives headache. That is why people with migraine often get aura before the headache sets in, as the body overcorrects it.

Depending on if your effect is from the blood supply or eye muscle cramping you would probably be able to modulate the effect by either vasodilators, or by correcting deficiencies that cause muscle cramping.

Well, I have not had deficiencies for the past 30 years, or possibly all my life.

And vasodilation medication can have its negative side effects too.

Tadalafil/cialis is pretty side effect free, actually, it is often recommended to be used anyways for e.g. bening prostate hyperthrophy.

So it is not like it would be some harsh drug to take

    Be careful, anything you inject in your body has an impact on you. If it's a vasodilator, then you can become 'resistant' to vasodilation after a while of taking cialis, especially when you'll stop taking it. Just like people who trigger their insulin too much end up not producing enough of it. Just like about everything actually. It's called homeostasis. If you take only small amounts here and there, shouldn't be a problem, but don't think it's completely innocent.

      How does Cialis work for boners? Do you have to wait? Does it feel different?

        Liberator005 Yes, I was expecting that many on this forum will be against having any resolution to this problem. Even if there was a new display that does not cause any problems, many would find something wrong with the tech and rather resume with the problematic tech.

        Tadalafil is not an injectable drug and I would you to read up on it before frankly posting so ignorant comments

          Sunspark The daily 2.5 mg - to 5 mg is a low dose that supposedly enables you to have sex any time. I don't really notice that much difference, since I've never had any problems in that department. Maybe better morning wood.

          Liberator005 "Based on our understanding of how Cialis works, Cialis does not lose potency over time. However, the effectiveness of Cialis in obtaining erections may decrease if vascular insufficiency caused by underlying medical problems is worsened."

          But like I said, when you don't want a solution, you will always find something wrong with the solution.

            But to add, I of course hope that instead of us having to take medication, manufacturers would pay attention to the harmful effects of flicker and revert back to manufacturing displays that don't irritate the eyes

            You didn't understand my comment I think. When I say inject I just mean something that enters your body whether is by drinking, eating, whatever else. I'm not saying you're using a needle lol.
            Also, it's just a warning. Don't know why you're so defensive about it. If you're satisfied then fine, do what you wish.

            As for a solution, I have a working setup for now. And a 2015 phone. For luck, I don't need a car right now, but I plan to buy one from years ago cause I had to sell the last one I bought cause of eye strain.

            If you're interested, I would suggest you try iodine supplementation, especially Lugol cause it's the purest. The others are shit in my experience.
            I took iodine for other reasons but it helped greatly vs eye strain and feeling incomfortable in front of screens.
            So, could give it a try.

              15 years ago there it was quite common for biohackers to recommend iodine, especially Lugols for everything. I was taking for a couple of years, but never noticed any benefit.

              But iodine is something to caution against very easy to take too much and many people have ended up with hypothyroidism as a result.

                Liberator005 I took iodine for other reasons but it helped greatly vs eye strain and feeling incomfortable in front of screens.

                Can you please elaborate? I have never heard of this supplement...why do you think it helped against eyestrain? Thanks.

                  AGI Iodine is in e.g. table salt (Lugol's is a brand). The idea in the Paleo diet folks is that when you don't consume table salt, you are iodine deficient. That might well be true if one really avoids all processed foods and does not eat adequate seafood. But I think actual iodine deficiency is rare nowadays. Of course, there is a reason why it is being added to table salt.

                  But it won't do anything for the eyes.

                    Maxx Thanks. I have not bought salt for 20 years but I eat out a lot unfortunately, and can easily go from zero salt to salty without the slightest problem.
                    I think I will pass on this one!

                    I'm taking fluxarten which is still a vasodilator and works well but it gives me some side effects if I take 10mg. Someone on the forum had reported an improvement by taking minoxidil (for alopecia) in tablet form which is always another vasodilator.

                    I would also like to try minoxidil tablets since I take it topically.

                    I decided to experiment with iodine.. I probably am deficient.. I don't use iodized salt, don't buy seafood, etc. so my only source of it is from milk.. as it turns out I had 6 packs of expired seaweed here, so let's see how I feel after 6 days.

                      AGI

                      Iodine is a very powerful antiseptic. It is for example the main component of Betadine.

                      In general though, iodine is just what thyroid requires to function properly. It's naturally mainly found in sea food. And in the 20th century, most occidental countries began to add it to table salt to stop goiters among the population. Since then, the majority of countries in the world add it to table salt, to cattle feeds and so on...

                      I agree with Maxx that it's quite hard to be iodine deficient nowadays if you eat average occidental diet. Though certain countries have no iodine salt supplementation but it's quite rare (Lebanon and Israel for ex). Also there are wide differences in the amount of iodine added to salt among countries. Norway adds 5mg/kg, United states and Canada add 76mg/kg... And supplemented salt is not always used.

                      Certain doctors like David Brownstein advocate that we all are super iodine deficient cause other halogens (particularly fluoride and bromine) are over proliferating in our environment (water, food and salt additives, mattresses and furnitures, treated wood floors...) According to him, those halogens compete with iodine absorption. And he thinks we need way more iodine to get rid of the excess bromine and fluoride that accumulate in our bodies.

                      His views are seen as controversial in the medical world though so I don't know if he's right or wrong.
                      Anyway precaution is necessary if someone tries to supplement with iodine, especially lugol cause it's very concentrated.
                      Some people on internet say it works like magic with many benefits, some say it has triggered thyroid issues with them like subclinical hypothyroidism or auto immune thyroid issues.

                      I took it cause I was feeling fatigued and I thought my new mattress was making me sleep bad (I still think it's the case). You know this smelly new mattresses that smell petrol and chemicals like shit ?

                      I didn't take much, I took like 1 drop of Lugol's 5% every week for 2 months approximately. And I have to admit it was very beneficial for me, I felt more energetic, more lively, slept way better, less anxious. But at the end I was feeling like I could get "addicted" to it and would need it more and more. Excess iodine can disrupt the thyroid. So I've just decided to stop it altogether. I make sure I get enough iodine through my diet. I may need to take it again in the future.
                      My personal stance on iodine is that it's something that helps in a "bad" environment.
                      In general, I dislike supplements and I have never taken any in my whole life until this iodine. I had an intuition that I needed it and it did was very beneficial for me for the time I used it.

                      If any wants to try I would just advocate precaution, and never take too much at once.

                        If you do so, I would suggest to use Lugol. The 2% or 5% one. Take only one drop and see how it goes for the next days.

                        Really avoid any brand that don't use Lugol's protocol.
