Short version:
Do the 20-20-20 rule before you buy fancy screen protectors and glasses.

Long version:
This is not specifically related to computers. Your eyes are made up tons of different little muscles. Different muscles are used to adjust the eyes to focus on things of different distances. (Regardless of your sightness, the muscles are still being used)
Just like holding a squat for a long time, your eye muscles will tire if they're holding for too long, this is why you get blurry eyes --it's the muscle getting fatigue. No type of lens will help against muscle fatigue, and there's a good chance that your blurriness is from this fatigue and not blue light.
