Nah, virustotal does that stuff all the time. Two detections is low out of all the malware scanners it used. I usually just use malwarebytes.

I understand, I’m not accusing or implying the product is malicious. However, I have password managers, access banking websites, etc so I’m cautious of exes from smaller developers. I wasn’t able to easily find the real identity of OP but the binary is code signed by a registered company it seems.

I will submit a request for exception/deeper review to the vendor that flagged the exe. I can also offer a full refund and reversal of the sale if you can not make use of the software at the moment due to your security concern. The exe and the installer are signed by the company I established for the project Refractify LLC.

> The effect can be tried live on the site

I tried the button on both Safari (initially) and Chrome, and I'm struggling to understand if I'm actually seeing what I should see. When on, zooming in to the text shows it's turned a very slight green shade of grey, vs grey when it's off. Visually that's the only difference I saw.

Perhaps I misunderstood "blurring the blue and green channels". I expected some sort of slight but noticeable blur, ie across pixels, but should I actually be seeing _blending_ of the blue and green channels, ie colour mixing but on a per-pixel level?

This seems great, but I have 2 questions: 1. Since this is for "early myopia", does it mean it is useless for adults? If not, which groups of adults will find it useful? 2. What do you think about this and is this even related? > The overall findings are equivocal with under‐correction causing a faster rate of myopia progression. There is no strong evidence of benefits from un‐correction, monovision or over‐correctio…

Thank you, 1. As long as the myopia is progressing there is an opportunity to slow that and avoid complications of high myopia. While screen altering may in principle go beyond the effectiveness of optical devices for myopia control as we can provide arbitrary input to the retinal neural network, realistically myopia reversal for adult humans is not considered achieveable. Intervention should ideally be started as so…

May I suggest an anecdote on why some studies have reported undercorrection progressing myopia: as my far sight deteriorated, without correction, I had more incentive to do "near work" like look at screens or look at books (because they were not blurry), than spend time outdoors (because they are a little blurry).

This is brilliant, thanks for making this. I am currently trying it out on Chrome and I can feel the difference. Any future plans of bringing this to the mac? I recently made an app[1] in the similar space for mac and I would love to collaborate to bring this to the mac if you'd be interested. BTW, all the links in your footer except privacy policy are 404s [1] https://lookaway.app

I would love a mac version!

The Mac version is in progress.

Thanks. Your response reassured me. I've ran the app and it works as described, finally, no suspicious behaviour was observed with procmon.

> This makes the screen look on the retina naturally as if it was at a greater distance. You can also do this the low tech way by using dirt cheap plus lens glasses. With the added benefit that they make a tiny phone screen look as huge as a cinema screen.

If you induce myopic defocus by plus lenses you create an urge to move the screen closer, which removes the effect. We need to achieve the right defocus on the retina. Wheres with the software solution you can not "cheat" by moving closer.

That’s true. Tends to shift the problem towards having horrible posture.

Congrats! For anyone who's interested, there's a group of us dedicated to natural myopia reduction at reducedlens.org, which is a free and open-source fork of endmyopia. I've even started measuring my axial length to try and get better data on if this stuff actually works (only one measurement so far though, so nothing interesting yet). The nature paper was pretty crazy. Basically because blue bends more than red (th…

ReducedLens is absolute quackery! This is why I hate myopia discussions. Myopia is not reversible, if you think it is, you don't understand what axial elongation actually means.

Are there any publications you can point me to that show the techniques there are ineffective?

How is it absolute quackery?

"Myopia is not reversible, if you think it is, you don't understand what axial elongation actually means."

There was a member on the forums who was measuring his axial elongation while at the same time applying the reduced lens method. His result is shown in the following plot.[0] It is a significant improvement that can't be ignored, and can't be explained by day to day fluctuations or measurement error. So we know that at least some level of axial elongation can be reversed, and the idea is not complete quackery.
