Vision does not stabilize at a particular age; rather, it is a gradual process where vision begins developing from childhood through adolescence and finally stabilizes in early adulthood. As a teenager, the eyes are physically developing, especially in terms of eyeball length, which affects light hitting the retina. Ongoing eyeball development in teenagers is one of the major contributors to vision error, especially myopia, which continues to worsen during this stage of life (Carr & Stell, 2017). As the retina has not reached complete structural maturity, teenagers experience constant shifts in their vision correction. Even with puberty-driven physiological shifts, including reading to study for educational requirements related to screen time, this instability in vision in teenagers is considered normal rather than abnormal.
As people progress through their late teens and into their early twenties, the rate of physiological growth in the eyes slows and ceases. Most medical professionals would agree that eyes are fully developed in terms of size and shape by their early twenties, which is why vision stops being inconsistent during this time (All About Vision, n.d.). When the eyeball stops growing in length and the cornea and lens reach a fixed shape, vision prescription stays constant because the prescription won't need to be altered very often anymore. This is why ophthalmologists will recommend patients with vision difficulties put off getting permanent corrective surgery, such as LASIK, until a prescription remains consistent for a year to two years before opting for this option (Mayo Clinic, n.d.). Some people may have a prescription fluctuation during their early twenties if they have high myopia.
Biological reasons are primarily responsible for vision stabilization in early adulthood. At this stage, all major physiological developments in the eyes have occurred, including full maturity of vision centers in the brain. Once vision centers in the eyes cease growing, vision is not prone to many other developments in the eyes and therefore remains constant in the 20s and 30s among most adults (WebMD, n.d.). But this stability will not last for a lifetime. At this time, very soon after turning 40, most people experience a vision problem in which eyelens stiffness starts, making it very problematic to focus on any items close by (Mayo Clinic, n.d).
Mayo Clinic explains this vision loss in middle-ages is a normal psychological process and does not relate to vision changes experienced during one’s adolescence or early adulthood.
Overall, the typical pattern for vision development is predictable. Everything fluctuates in adolescence because of the constant growth of the eyes, slows down in the early to mid-20s when the eyes have finished growing, and progresses with age in later adulthood. The knowledge of when and how vision stabilizes can show how teenagers need updated vision, why youngsters are told to delay vision correction, and why follow-up vision checks are necessary despite a stable vision pattern at any age.
