A blend of chokeberry, honeysuckle berry and bilberry extract improved near visual acuity and conjunctival hydration in presbyopic subjects, a Polish study found.  

The randomised, double-blind, cross-over study evaluated 23 presbyopes over the age of 50 with extensive work-related screen time exposure. Over a period of six weeks, the group was given a mixture of chokeberry, honeysuckle berry and bilberry (AKB) plant extracts (400mg twice daily) or placebo.  

Preliminary results showed the AKB supplement improved near visual acuity in 92.3% of the patients, while conjunctival hydration improved in 61.5%, demonstrating the potential effect of AKB supplementation in patients with dry eye syndrome, said researchers.  

The study, ‘Extract from Aronia melanocarpa, Lonicera caerulea, and Vaccinium myrtillus improves near visual acuity in people with presbyopia’, was published in Nutrients.
