Is it common to get blurry vision when looking at a computer screen?

Frequently. We normally blink around 1000 times per hour, but when you stare at a computer your blink rate may go down and tears evaporate faster. The surface tension of the tears is what creates a smooth surface for bending (refracting) light, so when your eyes are dry things go in and out of focus when you blink. Use artifical tears.Try to lower the computer screen, so there is less surface area to dry out.
Computer eye syndrom. Yes this possible but should only be temporary unless you need spectacle lens correction.

Presbyopia. Not knowing your age I would suggest you get your Ophthalmologist to refract you for glasses. And see your physician for ringing in the ears or tinnitus. It may be as simple as wax in the ears or an infection. . Read more...
Two common things. Often the muscles which coordinate focus of the eyes fatigue when used a lot/intensely such as the work you describe. Enlarge text, adjust brightness/contrast & room lighting, lower monitor (so your eyes can see it without opening so wide), take mini-breaks every 20 minutes. The ringing/tinnitus is likely unrelated. It most often results from high frequency hearing loss. Go to entnet.org/tinnitus. Read more...
