It is mainly because of elevated screen time and decreased outdoor activity, which causes myopia or nearsightedness. Ophthalmologists usually prescribe the use of glasses or contact lenses to restore vision. However, red light therapy presents a natural alternative for restoring eyesight. Red light therapy can repair the retina and even improve visual perception of far objects. Read on to discover how red light therapy helps improve vision and reduce myopia. Understanding Myopia: Causes and Progression Myopia, or nearsightedness, is when you can see objects clearly up close but distant objects appear blurry. This occurs when the eyeball becomes too long, or the cornea is too steep, causing light to focus in front of the retina rather than directly on it. Nearsightedness, or myopia, was something that primarily adults had to worry about in the past. However, today, many more children and young adults are becoming nearsighted. This is mostly attributed to the tremendous amount of time they spend gazing at screens. Gazing at phones, tablets, and computers for hours, particularly close up, puts tremendous pressure on their eyes and makes them even more nearsighted. In addition, studies have shown that insufficient time outside under natural sunlight makes the issue arise sooner. Certain eye physicians are even suggesting schools employ more natural light to aid in the protection of children's vision. Myopia typically begins during childhood and worsens over a period. If not controlled, it may result in serious eye issues such as retinal detachment, glaucoma, and macular degeneration later on in life. Challenges with Traditional Myopia Treatments You're likely aware of common treatments for myopia, such as wearing glasses or contact lenses. Doctors prescribe glasses depending on how weak your vision is, and people often wear contacts for special events such as parties or events. Although glasses enable you to see correctly, they don't cure the underlying problem, and contact lenses may sometimes lead to irritation or other eye problems with long-term use. With technological advancement, LASIK surgery is now an increasingly common means of correcting one's vision for good. Still, it's costly, not an option for children, and risky as it can result in dry eyes or problems after some years. Myopia will progress with age, and even such drops as atropine, designed to decelerate it, have constraints. They may work a bit, but they can bring side effects such as sensitivity to light and poor near vision. How Red Light Therapy Supports Eye Health in Myopia The Science Behind Red Light Therapy for Vision Improvement Red light therapy is a painless and non-surgical method of improving eye health and retarding declining vision. It achieves this by increasing energy levels in eye cells, encouraging the retina to heal itself, and enhancing overall vision. Studies show that exposure of the eyes to soft red light can relieve eye strain, improve circulation, and preserve eye function. Some studies suggest that regular use of red light therapy may slow myopia in children, and it is thus a promising therapy to look into over conventional approaches. Unlike glasses or contact lenses, which only allow you to see better, red light therapy works on a deeper level, allowing your eyes to stay healthier and function better in the long run. Does Red Light Therapy Work for Myopia? What Research Says Research has shown that red light therapy has the ability to delay eyesight deterioration in kids who have myopia. Experts opine that it does so by delivering energy to cells in the eyes, increasing circulation, and keeping eyes healthy. There is some evidence that has formed to show that kids who regularly used red light therapy didn't need thicker glasses right away compared to others. While it won't fully prevent myopia, it could be a valuable method of managing it, especially if used in conjunction with more outdoors and less screen time. Clinical Studies on Red Light Therapy for Myopia Management Study 1: Evaluating the Effectiveness of 650 nm Red Light Therapy for High Myopia Control in Children Objective To evaluate the efficacy and safety of repeated low-level red light (RLRL) treatment at a 650 nm wavelength in retarding high myopia progression in children and adolescents. Results One hundred ninety-two children (ages 6–16) were studied, 96 of whom were treated with RLRL therapy and glasses, and 92 who wore glasses only. At 12 months, the RLRL group had a mean axial length (AL) reduction of -0.06 mm, whereas the control group demonstrated an increase of 0.34 mm. 53.3% of children in the RLRL group demonstrated significant axial shortening (>0.05 mm). The spherical equivalent refraction (SER) change was +0.11 D in the RLRL group versus -0.75 D in the control group, signifying reduced myopia progression with treatment. Conclusion Repeated low-level red light treatment (650 nm) is a safe and effective technique to decelerate high myopia progression in children, thus a desirable addition to myopia management. Study 2: Enhancing Eye Accommodation with 830 nm Low-Level Laser Irradiation at Auricular Points Objective To assess whether low-level laser irradiation (LLLI) at auricular points with an 830 nm wavelength can enhance eye accommodation and decrease refractive error. Results The participants were tested with and without LLLI during a 30-minute break. In the treatment group (LLLI), refractive error was reduced by -0.12 D (-0.18 D), whereas in the control group, it was -0.05 D (-0.02 D). The amplitude of accommodation (AA) in the experimental group was 7.98 ± 1.35 D, demonstrating a quicker recovery of eye-focusing ability. Conclusion Low-level laser irradiation at auricular points with an 830 nm wavelength is more effective in restoring eye accommodation compared to natural rest and, thus, may be an effective method for alleviating eye strain and vision recovery. Study 3: Low-Level Red Light (LLRL) Therapy for Myopia Control in Children Objective To determine the efficacy and safety of once-daily 650-nm low-level red light (LLRL) therapy in retarding myopia progression in children aged 6 to 12 years. Results Myopia Progression: At 12 months, children in the LLRL treatment group had significantly reduced myopia progression than the control group (−0.24 D vs. −0.65 D). Axial Length (AL): The LLRL group decreased slightly in AL (−0.11 mm), whereas the control group increased (0.26 mm), which reflects improved eye health in the LLRL group. Safety: No retinal injury or other safety issues were noted in fundus photographs. Conclusion One year of daily exposure to 650-nm LLRL slowed myopia progression and axial elongation effectively in children without eliciting detected safety hazards. More trials are necessary to verify these findings in other environments and assess long-term benefits.
