Coffee is a drink that contains caffeine as one of its major ingredients in its composition. Coffee is being consumed throughout the world by different populations of different age groups very commonly in the morning and in the evening to stay awake and active as well as energetic to complete different types of chores and work. Coffee if taken in moderation does not cause any harm to the body or eyes. Like any other thing, coffee can also cause harmful short-term and long-term effects on human health and body if taken in excess and up to the toxic level as the excess of everything is bad.

Moderate coffee consumption and its effects on the Eyes:

CGA or chlorogenic acid is a compound that is present in raw coffee beans. CGA acts as an antioxidant and has a beneficial role for the body. It also has a role in the betterment of the health of the eye. Different studies and researches show that CGA that is present in coffee might have a role in preventing Retinal degeneration and hence prevents the deterioration of the function of the retina, the back part of the eye that lets the eyes receive and organize the things and information a person sees. CGA in coffee also prevents the occurrence of Hypoxia which can further lead to the onset of other various eye diseases such as diabetic retinopathy, macular degeneration, and glaucoma, which may result in different varying degrees of blindness.

Effect of coffee consumption on dry eyes:

Dry eyes refer to a condition in which tears are not produced in the right consistency to keep eyes moist so eyes do not get enough protection from dust particles and gunk that leads to scratchiness and irritation of the eyes. Few studies and researches on a smaller level have shown that coffee might help in increasing the number of tears in eyes of a person with dry eyes by showing a boost in tear production. Studies also showed that people who consumed coffee had lower rates of dry eye than people who didn’t. 

Effects of excessive coffee consumption on Eyes:

Short-term effects include blurred vision, eye twitches, burning sensation, and tingly eyes and these can cause discomfort so excess coffee intake should be avoided. Long-term effects include the development of glaucoma and other negative effects on eye health.

Anything, be it coffee or any other thing should be consumed mindfully to prevent any complications in the future.
