T1) The detrimental health benefits of smoking have been widely discussed, both in academia and in daily circumstances. However, one fact that seems to escape many conversations is that smoking can harm our vision.

T2) To begin, both tobacco chemicals and smoke itself affect with tear production, which can greatly irritate the eye, causing conditions like dry eye or itchiness and irritation.

T3) Tobacco can also affect the blood vessels in the eyes, leading to damage and overall less oxygen reaching the eyes than is needed for adequate vision. 

T4) Smoking can also lead to certain diseases, such as cataracts, macular degeneration, and diabetic retinopathy.

T5) All these conditions can have serious affects on vision, including black spots, blurry vision, and sometimes leading to complete blindness. In fact, smokers are four times more likely to go blind in old age than an average adult. 

T6) Another interesting fact is that nicotine poisoning can lead to difficulty differentiating between red and green colors.

T7) However, it’s not just smokers themselves who are affecting by smoking. Secondhand smoke has been shown to cause problems, not only in the eye anatomy, but also in the functioning as well. In fact, studies show that even secondhand smoke increases nonsmokers’ risk of sight loss. 

T8) While these facts may seem intimidating, it’s important to make healthy choices for ourselves and others concerning smoking.

Really interesting! I was wondering if you found anything on vaping or if most of the research was on smoking? It could be cool if you linked to the other post on drugs and the eyes too. Nice job!

For T4 I would say smoking increases the risk for XXX

How does smoking lead to difficult in differentiating red and green?  Was one of the citations for that?

This is great! The only thing is in T7 when you say "who are affecting by smoking". I think writing 'affected' rather than 'affecting' would make it flow better. Great job on the post!
