Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. 
No,  tooth extraction  does not cause  vision problems or loss or blurring of vision. 
So do not worry about it. 
The symptoms  that you are facing can be due  to 
sinus related problem  that can be secondary to tooth extraction. 
However  if it is sinus related  then it can be very well treated. 
So my suggestion is to consult an oral physician and get evaluated. 
An 
x ray can be done for confirmation.
For now put decongestant nasal drops like  
Otrivin and do steam inhalations. 
Avoid vigorous  snuffing of nose. 
Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
