In Spain, the average life expectancy has already exceeded 84 years, but the quality of these additional years directly depends on the ability to see. Ophthalmologists at the Miranza clinic propose the concept of “visual longevity” — not as a promise of eternal youth for the eyes, but as a systematic approach to preserving vision in the face of natural aging.
According to Fundación Salud Visual, eight out of ten people over 60 have vision or eye problems. The main threats are cataracts, glaucoma, and age-related macular degeneration. These conditions do not appear suddenly: changes begin after the age of forty, when the lens loses its elasticity and presbyopia appears.
The Miranza clinic emphasizes that vision loss is not an inevitable price for longevity. Modern ophthalmology has tools for early diagnosis and treatment. Regular check-ups from the age of forty to fifty allow for the detection of glaucoma before irreversible damage to the optic nerve, and laser trabeculoplasty provides less invasive control of intraocular pressure.
Cataract and presbyopia surgery using modern intraocular lenses simultaneously solves several problems: it restores clarity and corrects refractive errors. In the wet form of macular degeneration, intravitreal injections slow or stop the loss of central vision, although there are no effective methods for the dry form yet — research is ongoing.
The concept of visual longevity essentially comes down to the timely use of existing technologies, rather than new breakthroughs in slowing down the biological aging of the eye. This distinguishes it from more radical approaches in gerontology, where the focus is on the cellular level. Here, the key is regular monitoring and intervention at early stages.
Imagine a person who, at 75, still drives a car and reads without a magnifying glass: for them, the difference between “normal aging” and “visual longevity” is measured not by years of life, but by years of independence. It is this independence that Spanish specialists aim to extend.
Thus, visual longevity reminds us that aging is not only a biological process but also a manageable one through accessible medical practices, where prevention and accurate diagnosis yield greater results than waiting for the first symptoms.
