Even if you were right that your approach is somehow inherently easier, it is flat-out wrong that other approaches lead to "brain impairment". On the contrary, it is well-established that challenging the brain prevents or at least delays brain impairment.
My phrasing "impairment" is of course somewhat exaggeration. It cannot be compared to harm due to smoking for example. However it also known that many people who do big amount of information processing and intensive reading are subject to earlier loss of the vision sharpness. And I feel it myself. How exactly this happens to the eye itself is not clear for me. One my supposition is that during the reading there is very intensive two-directional signalling between eye and brain. So generally you are correct, the eye is technically a camera attached to the brain and simply sends pictures at some frequency to the brain. But I would tend to think that it is not so simple actually. You probably have heard sometimes users who claim something like: "this text hurts my eyes" For example if you read non-antialiased text and with too high contrast, you'll notice that something is indeed going wrong with your eyes. This can happen probably because the brain starts to signal the eye control system "something is wrong, stop doing it" Since your eye cannot do anything with wrong contrast on your screen and you still need to continue reading, this happens again and again. This can cause indeed unwanted processes and overtiredness of muscles inside the eye. So in case of my examle with Chinese students, who wear goggles more frequently, this would probaly mean that they could "recover" if they just stop reading a lot.
"challenging the brain prevents or at least delays brain" Yes but I hardly see connection with this case, I would probably recommend to make some creative exercises, like drawing or solving puzzles for this purpose. But if I propose reading books in illegible font than I would be wrong in any case.
And it also makes no sense that it would cause visual impairment, either. Comparing glyphs is a higher-level task in the brain, it has little to do with your eyes.
You forget about that whith illegible font or wrong contrast for example you *do* need to do more concentrarion, This causes again your eye to try harder to adopt to the information you see, reread, which again affects your lens and eye movements. Anyway, how do you think then this earlier vision loss happens? You'd say I fantasise?
