If you are one of many people who work 8-10 hours a day, on a computer, you must make your workspace better. If you work in a company, then you don’t have a lot of freedom to change anything you want, but if you work from home, then you can and you should replace everything you can.
Let’s start from the beginning. Because you work on a computer, it is the most important thing. Web browsers and software are bigger and they require stronger computer. This means that you cannot use some old computer. So, this is the first thing you must replace, if it is needed. A PC with i3 processor and 4 GB of RAM is usually enough, unless you are a web designer or programmer. In that case, you must use i5 or even better i7 processor and more RAM. A computer mouse is more important than you may think. Cheap computer mouse will last a couple of days, so it isn’t an option. The same thing is with a keyboard. Always but input devices made by known manufacturer, or buy expensive ones.
Your chair is equally important. An ordinary office chairs are not the only option. All of them cannot provide enough support for your back, so you will develop back problems if you work a lot. Big and again, expensive, office chairs are the best option. Glasses that are designed to protect your eyes from monitor rays are essential. They are cheap and they won’t affect on your vision.
