Dear Saniya1786,
During the healing phases, you may notice some symptoms in front of the computer but I would follow the recommendation of your eyeMD.

Returning to work after 2 weeks is fine as long as your doctor doesn't have you positioning your head due to the gas bubble. So check with your doctor.
Computer work, watching tv, reading, do NOT effect your eye health, in terms of causing retinal detachment, or reoccurence of a RD (in fact the only thing these activites may cause is dry eye and some eye strain/fatigue).
Scientific research shows that the overall likelihood of developing PVR (proliferative vitreoretinopathy), aka scar tissue, is about 8-10% of all RD cases. The data as far as age and PVR is mixed. Overall the success rate for re-attaching the retina is over 90%. Although the actual visual acuity rates vary, rarely does an RD (in adults) lead to no light perception, even in complex cases.
At only 2 weeks post-op you still have a ways to go in the recovery process so you should still be under the care of your retinal specialist. You should consider asking your surgeon these questions and/or his assistants.
