Richard buys Thealoz Duo for his mum who is suffering from Macular Degeneration disorder (MD). Macular degeneration is a common eye disorder among people over 50. It causes blurred or reduced central vision, due to thinning of the macula. The macula is the part of the retina responsible for clear vision in your direct line of sight. Symptoms of this have resulted in her having a slight loss of sight.
Richard got Thealoz Duo recommended by his mother's eye doctor where they were told that Thealoz Duo is designed to help moisturize your eyes and prevent dry eye.
After buying it for the first time, his mum found that over time taking the eye drops regularly, they found that her eyes saw improvement and will continue to use it.
