STUDY: Too much aspirin over time might damage eyesight

(CBS News) — An aspirin a day over a long period of time might not be good for your eyesight. 

Researchers at the University of Wisconsin warn that people who used Aspirin regularly for at least 10 years, are more likely to be at risk of age-related Macular Degeneration- a condition that can lead to blindness.

However scientists say the risk is small and that more research is required.
