To me, it's just a horrible sentence. I'd say something like, "Computers and televisions play a critical role in damaging our eyesight/vision." Eyesight, is vision. I think the person who wrote this was a plank.

I am not going to correct the grammar seriously nor to to argue about the opinion of the writer here. However, the 2nd line is ungrammatically correct. The correction is capitalized. "Computers and televisions play a critical role IN AffectING our eyesight and vision."

The article was compiled. I googled and found the original: Some of the most common causes OF poor eyesight ARE THE result of our lifestyle, IN both work and play. Computers and televisions have played a critical role in the effects/DAMAGE of our eyesight and vision. CHOOSE BETWEEN EYESIGHT OR VISION, THEY MEAN THE SAME THING. Computers and televisions have played a critical role in the effects/DAMAGE of our eyesight. Computers and televisions have played a critical role in the effects/DAMAGE of our vision. http://ezinearticles.com/?Eye-Exercises-to-Improve-Vision---Restore-20-20-Vision-Naturally&id=3901027 Is this correct? :) Is now :)

The verb affect means "to influence." The verb effect means "to bring about." Effect is more frequently employed as a noun to mean "the result". Some examples of sentences are as follows: 1. The new law may affect our expansion program. 2. We are hoping to effect a few minor changes. 3. They could not foretell what the effect would be. Here are the correct way for this article: "Some of the most common causes for poor eyesight is the result of our lifestyle both work and play. Computers and televisions play a critical role in how it effects our vision and eyesight." What is the meaning of "to effect of our eyesight and vision"? Additional Details: The article was compiled.
