If you’re looking to reduce worsening eyesight, there are proven strategies that range from simple daily habits to medical interventions. Myopia (nearsightedness) is the most common form of progressive vision loss worldwide, and most of the research on slowing eyesight deterioration focuses on it. Whether you’re a parent concerned about a child’s worsening prescription or an adult dealing with eye strain and blurry vision, the approaches fall into a few clear categories: lifestyle changes, optical devices, eye drops, nutrition, and surgery.
Spend More Time Outdoors
Outdoor light exposure is one of the simplest and best-supported ways to prevent myopia from developing in the first place, especially in children. Each additional hour spent outdoors per week reduces the odds of developing myopia by roughly 2% to 5%. The benefit appears to come from the intensity of natural light itself, which triggers biological signals that help the eye maintain its proper shape during growth.
Practical recommendations from the research include at least one hour of recess outside the classroom daily, classrooms with large windows, and organized outdoor activities. For adults, the protective effect against new myopia onset is less relevant, but time outdoors still gives your eyes a break from the close-focus demands that contribute to strain and fatigue.
Manage Screen Time and Reading Distance
How close you hold screens and books matters more than most people realize. In studies of children, reading at a distance closer than 30 centimeters (about 12 inches) was associated with more myopic eyes. When the distance dropped below 20 centimeters, the odds of myopia increased further. Continuous reading for more than 30 to 45 minutes without a break compounded the risk.
The 20-20-20 rule is a widely recommended strategy for digital eye strain: every 20 minutes, look at something 20 feet away for 20 seconds. A clinical trial found that following this rule with reminders reduced both digital eye strain symptoms and dry eye symptoms. The catch is that the improvement didn’t persist once people stopped following the rule, so consistency matters. Think of it as an ongoing habit rather than a temporary fix.
For young children, the World Health Organization recommends no screen time at all for infants under one year. Children aged one to two should have no sedentary screen time (or no more than one hour at age two), and children aged three to four should stay under one hour daily.
Specialized Glasses for Myopia Control
Standard glasses correct blurry vision but do nothing to slow the underlying progression of myopia. A newer type of lens, called DIMS (Defocus Incorporated Multiple Segments), is specifically designed to slow eye elongation in children. These look like regular glasses but contain hundreds of tiny lens segments that create a peripheral defocus signal, which appears to tell the growing eye to slow down.
In clinical testing, children wearing DIMS lenses had about 51% less myopia progression over one year compared to children in standard single-vision lenses. The DIMS group’s eyes also elongated significantly less (0.17 mm versus 0.30 mm). Importantly, the lenses didn’t negatively affect quality of life, so kids adapted to them without major complaints. These are typically prescribed by an eye care professional specializing in myopia management.
Orthokeratology Lenses
Orthokeratology, often called “ortho-k,” uses rigid contact lenses worn overnight to temporarily reshape the front surface of the eye. You remove them in the morning and see clearly during the day without glasses or contacts. Beyond the convenience factor, ortho-k lenses also slow myopia progression in children by 40% to 60% compared to standard correction. The reshaping effect is reversible, so if you stop wearing the lenses, your cornea returns to its original shape within days to weeks.
Low-Dose Atropine Eye Drops
Atropine eye drops at very low concentrations are one of the most studied medical treatments for slowing myopia in children. Full-strength atropine (1%) is the most effective at halting progression but causes significant side effects like light sensitivity and blurred near vision. Research has zeroed in on much lower concentrations that balance effectiveness with comfort.
The ATOM 2 study, which followed 400 myopic children, initially suggested 0.01% atropine as the sweet spot. A later trial called LAMP, involving 438 children, found that 0.05% atropine achieved better results while still maintaining a good safety profile. These drops are used nightly over months to years and require monitoring by an eye doctor. They don’t eliminate myopia but meaningfully slow how fast a child’s prescription worsens.
Laser Eye Surgery for Adults
If your goal is to reduce your dependence on glasses or contacts as an adult, laser surgery (most commonly LASIK) permanently reshapes the cornea to correct refractive errors. You need to be at least 18, though many surgeons prefer patients to be 21 or older, when the prescription is more likely to have stabilized. Your prescription should have been stable for at least a year, and your corneas need to be thick enough and healthy. People with unstable prescriptions or thin corneas are not candidates.
LASIK corrects the current state of your vision but doesn’t prevent future changes. If you’re in your 20s or 30s and your myopia is still progressing, surgery may not be the right timing. It also won’t prevent age-related changes like presbyopia (difficulty focusing up close after 40).
Nutrition That Supports Eye Health
Two plant pigments, lutein and zeaxanthin, accumulate in the retina and act as a natural filter against damaging light. The average American adult gets only 1 to 2 mg of lutein per day from food, but research suggests that around 6 mg daily is needed to reduce the risk of age-related macular degeneration. The AREDS2 trial used 10 mg of lutein and 2 mg of zeaxanthin daily for an average of five years with no significant adverse effects beyond mild skin yellowing in some participants. Dark leafy greens like spinach, kale, and collard greens are the richest food sources.
Omega-3 fatty acids from fish have been studied for dry eye, which often accompanies heavy screen use. A large clinical trial tested a daily dose of 2,000 mg of EPA and 1,000 mg of DHA (both types of omega-3s found in fish oil) against a placebo in people with moderate to severe dry eye. The results were more mixed than many people expect, so omega-3 supplements aren’t a guaranteed fix for dry eye, but they remain a reasonable part of an overall eye-healthy diet. Fatty fish like salmon, mackerel, and sardines deliver these nutrients naturally.
Combining Approaches Works Best
No single strategy eliminates eyesight deterioration entirely. The most effective approach, particularly for children with progressing myopia, combines multiple interventions. A child might use low-dose atropine drops alongside DIMS lenses or ortho-k, spend more time outdoors, and take regular breaks from near work. Each method targets a slightly different mechanism, and the effects can add up.
For adults, the combination looks different: managing screen habits, maintaining good nutrition, using proper correction, and considering surgical options when the prescription stabilizes. The earlier you start with any of these strategies, the more cumulative benefit you get over time.
