Chinese scientists have found that drinking coffee and tea can have a positive effect on the health of the back of the retina, which is responsible for central visual acuity.

Nutrients magazine notes that researchers surveyed more than 35,000 people about the average number of cups of tea and coffee they drink per day over the past year.

According to their results, they divided the participants into four groups: from zero to more than four cups a day. They measured the thickness of the retinal macular nerve fiber layer using optical coherence tomography (OCT), which is a non-invasive imaging technique that uses reflected light to form the back of the eye. The image was then automatically analyzed by the built-in software.

After adjusting the results for age, gender, median total family income, poverty index, smoking, race, education, body mass index, sleep duration, and other factors, it became clear to the researchers that the thickness of the macular retinal nerve fiber layer increased in those who drank 2- 3 cups of coffee and tea per day.

Researchers warn against drinking instant coffee, which may be a risk factor for health problems, including neurodegenerative diseases.
