Do blurry glasses exist that you can just randomly buy?

There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?

Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice ๐.

It is different for simulated blurriness, because simulated blurriness can't be modulated by your ocular muscles, so they won't reflexively strain to focus.
You couldn't really achieve that effect by actually putting any kind of lens in front of your eyes though. That is not a simulation of blurriness, it is actual blurriness.
The primary way it would be bad for your eyesight is by inducing eye strain, itself a primary cause of blurred vision. It's a reflex of the subconscious brain - either your eyes will be constantly trying to focus, which strains them, or you're consciously unfocusing them, which also strain them.
If you had eye strain causing blurry vision naturally and didn't correct it with glasses, likely there'd be no downward spiral unless you have some other condition causing that. It'd potentially cause other issues like headaches or spasms though
This is the correct answer. It's like using an image with depth to work your depth perception: it won't work because you can't transition between each layer to bring them into focus. Seamen who stay in submarines for extended periods are prohibited from driving for quite a while when they get back on land because a submarine is too small of an enclosed space and your depth perception crumbles over time when it's not being used.
Turning your world into a blur will basically cause your eyes to try and hyper focus at all times, unable to do so. This will lead to massive eye strain but also a ton of headaches and other ailments. It is the opposite of relaxation for your body.
