What kind of screen filter?
1. I use antiglare screen which has come really handy, I had it replaced from the shitty Glossy screen that every company is selling today. The brand is Dell but I guess you are using a PC and 3M makes the best anti-glare screens for PC. Only Dell makes(and always did) and sells anti-glare screens with their cheap line of laptops(inpirons) or you have to go high-end. I also found Asus using really good screen+software on their budget laptops that control blue light radiation which bothers the eye.
2. There are a few softwares that protect your eyes like F.lux and the one I use…Hacker vision app for chrome. Also, previously discussed here.
3. There are few UV-protection eye glasses available that should do the job for cheap.
