Right eye blurriness. Please advise.

From past few weeks I was having issue with right eye. Intially one side of eye became red and after 10 days it got resolved. But heaviness with eye and pulling like sensation is there. While that time little blurriness is also seen which is there till now. This is happening with only right eye and left is fine. Before this happened for many days I was spending 16 hours a day on screen either laptop or mobile. Earlier also this is there like heaviness with the eye while movement and sometimes pain in right side of face, whenever stress is there. I have sinus issue on right side. Is this because of dry eyes or sight issue. When I see a bright light with only right eye then small light like a circle is seen around the light but in white colour only, like a blurred one. Internet searching is giving stress like glaucoma and all. Please advise.
