Can't the app include computation correction for the image displayed to a standard retinal distance? For that matter why not "correct" the image displayed per the "optics" of each user? One could use a little bit of existing hardware (eg: a bluetooth touchpad) to take the graphic inputs needed to define a "corrective/computational" reverse-Amsler grid.
Just a newbie here w/ a question and perhaps a vision/application well before VR. thanks.
The lenses are needed so you can focus on the screen when it is so close to your eyes. Moving the device further away isn't the best option, in part because it reduces the available field of view.
From oculus documentation:
The lenses in the Rift magnify the image to provide a very wide field of view (FOV) that enhances immersion
The lenses allow for a wider field of view keeping the screen size small at the same time.
See this YouTube video for a very interesting insight.

I know it's generally considered as insecure, but it really depends on situation. I don't want to replace valid screen lock, I want to have possibility to choose based on situation. 2 sample usecases:
kids: I want to enable her to watch show, but I would like to block 'work cooperation' on any of mine projects, and I need not to have spare hw available
at secure work site: any college need not to poke at my screen, he can trivially clone/get whatever he wants, because he has same access. So I would like to lock screen against jokers who would like to write something under my name, but while helping someone I'd like progress of some process going on my screen. Ie. ANY monitoring screen, where we want to show status 24*7, but disallow unauthorized input.
I don't expect even naive hacking attempts in these usecases, so not 100% bulletproof lock is fine.
Some time ago, there was project named pyxtrlock, but it was deprecated. Is there some replacement? Or is there better way how to secure monitoring systems?

I have lots of JPEGs from DSLR, and they are roughly about 5-6MB per JPEG. I open any of them using MSPAINT, and click the SAVE and notice the size immediately go down to 2-3MB.
Why? Is Mspaint doing a lossy or lossless compression?
Things Paint May be doing:
Using different quantization tables
Subsampling the Cb and Cr color components
Using optimal huffman tables.
Stripping out metadata.
You an run a JPEG dumping program on the two versions and compare the output to see the changes

When I enter a website, is there a way they would know that I'm using my Adblock filters to block a few images from loading/appearing?
Sure, there are a number of methods that can be used to detect the presence of an Adblock-like extension. Whether a site actually captures that data and logs it is another question.
See this SO question: How to detect Adblock on my website?
Here's a live demo: Adblock Plus detection demonstration
Generally, the technique is to write an invisible element onto the page that you know will be blocked if the user has Adblock installed, such as a JS file with the word "ad" in the title. Then, using jQuery, you can check to see if that element exists in the DOM. If not, then it's being blocked. Based on that result, you could display a message, send a PUT request to your server to log it, and so on.

This may be a simple question but, I heard that the only rule in working on the kernel is that you don't break "user space". So I was wondering what that means: To break user space and how does it happen?
Edit
It has been pointed out to me that this question is not suited for Stack Over Flow by #lurker so I will move it to Super User as #lurker suggests. (See below)
"Questions about general computing hardware and software are off-topic for Stack Overflow unless they directly involve tools used primarily for programming. You may be able to get help on Super User." – lurker, jww, SilentKiller
You're referring to Linus Torvald's first rule of kernel development. This note explains it: https://lkml.org/lkml/2012/12/23/75. I.e., when maintaining the kernel, do not do something which breaks user programs/applications. In other words, when making kernel changes, it is very bad to cause problems in the user's application "space". That doesn't literally mean memory. That means anything that impacts the user applications in a way that negatively affects its behavior (causes the program to malfunction). The note I cite also indicates at least one example.

Everything seams to work properly, I get fully functional UI, but in the work space there are only points with orientation arrows, they react as if there wore objects but neither objects nor the grid shows up. They appear in the render thou.
It sounds like you have zoomed way out from the objects in your scene.
ShiftC will reset the 3dcursor to the centre and reset the view.
. on the numeric keypad will zoom into the currently selected object.
Also there is a blender.stackexchange for blender specific help.
