This registered nurse discovered Longevinex and T Cell Zinc in late 2022 and immediately became a huge fan. Following corneal abrasions over 20 years previously, I had had to use non-medicinal lubricating eyedrops every night. Every day I can feel Longevinex helping my eyes remain properly moistened and clear of floaters. I am 73 years old and plan to be a customer forever. Dianna and her team should be congratulated on their work.
