So, I'll cut to the chase here. I work at a call center for my state's government, and at the job I'm regularly accessing people's private information for the purposes of identity verification. Understandably, this means that my office does not allow for employees to plug anything into their workstation computers that isn't directly provided by our employer, out of concern that a USB drive or other device that connects to the computer could have malware in it, giving some wannabe criminal access to information that could be used to steal someone's identity.
Unfortunately, this means that I'm stuck using the stock Lenovo peripherals that come with the ThinkCentre line of computers. ThinkVision monitor, membrane Lenovo keyboard, and terrible stock Lenovo mouse. Luckily, the desk chairs at the office are fairly nice, and have decent lumbar support, and I already have decent posture. However, I am still concerned about the longevity of my wrists, fingers, and eyes, as I do a lot of computer work both on and off the job. Gaming, personal projects like learning Blender, etc. So my question comes down to be rather simple, in practice:
Using stock peripherals, that I cannot change due to work circumstances to something even moderately more ergonomic, what are some things I can do to help with ergonomics? As mentioned above, I've already got pretty decent posture (though it can be improved upon - the lumbar support isn't the best, though it's a lot better than minimal support or no support, and I know I'm not perfect.), and as for the longevity of my eyes, I'm planning on getting a good pair of blue light-blocking glasses (though recommendations on ones that have clear lenses and actually work would be great, as we aren't allowed to wear tinted eyewear in the office). But does anyone have good resources for other practices, such as good wrist/finger stretches or exercises, that could help with preventing RSI or Carpal Tunnel?
