He dismantles popular misconceptions about blue light, eye exercises, sun gazing, dark circles, and the inevitability of vision loss. Allen details how lifestyle factors—screen time, time outdoors, diet, sleep, and systemic diseases like diabetes—directly reshape the eye and drive conditions such as myopia, cataracts, macular degeneration, dry eye, glaucoma, and floaters. Throughout, he emphasizes annual eye exams as a critical, low-friction way to detect both eye and whole‑body disease early, and gives practical, science-backed steps for everyday eye care.
