Hello.
Thanks for writing to us.
Smoking is not likely to affect your vision but working on the computer from a wrong angle can cause the

dry eyes and the increase in the cylindrical power of the specs. At your age usually the eyesight becomes stable with no further increase in the power.
I hope this information has been both informative and helpful for you. You can consult me again directly through my profile URL http://bit.ly/Dr-Praveen-Tayal
