Nowadays, myopia has become a common vision problem affecting many people, especially adolescents and adults who work at desks for long periods. Many are eager to know, “Can myopia be reversed?” and “How to reverse it?” In fact, whether myopia can be reversed depends on the type of myopia—true myopia and pseudomyopia. These two types differ fundamentally in their causes and management approaches. Only by addressing them appropriately can we protect our vision scientifically.
I. First, Distinguish Types: Pseudomyopia Is Reversible, While True Myopia Requires Control
To determine if myopia can be reversed, the first step is to distinguish between “pseudomyopia” and “true myopia” through professional examinations. This process relies on an ophthalmologist’s professional diagnosis, with common tests including visual acuity checks and cycloplegic refraction (which eliminates the impact of ciliary muscle spasm to accurately identify true myopia).
1. Pseudomyopia: A Reversible “Vision Alert”
Pseudomyopia is not true myopia. It occurs when the eyes are in a state of prolonged tension (e.g., long hours of looking at mobile phones, computers, or reading at close range), causing the ciliary muscles to contract and spasm continuously. This makes the lens bulge, leading to temporary vision loss. Simply put, it is a “stress response” of the eyes after “overwork.” It is common in adolescents and people who use their eyes intensively, especially when blurred vision suddenly appears after prolonged near-work.
Recovery Methods for Pseudomyopia:
- Relax the eyes promptly: Every 20 minutes of near-work, look at a green object or distant scene 20 feet (about 6 meters) away for 20 seconds. The “20-20-20” rule helps relieve ciliary muscle tension.
- Eye massage and hot compresses: Gently massage the acupuncture points around the eyes (e.g., temples, Jingming points) with your fingertips for 5-10 minutes daily. Before bed, apply a warm towel (around 40°C) to the eyes for 10 minutes to promote eye blood circulation and relax the ciliary muscles.
- Reduce near-work time: Temporarily cut down on using electronic devices like mobile phones and computers. Avoid reading or doing homework continuously for long periods; rest for 10-15 minutes after every hour of near-work.
- Medication support if necessary: If ciliary muscle spasm is severe, low-concentration cycloplegic eye drops (e.g., 0.01% atropine eye drops) can be used under a doctor’s guidance to relax the ciliary muscles. However, strictly follow medical advice—do not purchase or use them without permission.
In most cases, pseudomyopia can gradually improve within 1-2 weeks by following the above methods. Note: If pseudomyopia is not addressed promptly and ignored for a long time, it may develop into true myopia. Therefore, seek medical examination as soon as you notice vision loss.
2. True Myopia: Irreversible, but Progression Can Be Controlled
True myopia results from organic changes in the eye structure—axial elongation (the axial length of a normal adult eye is about 23-24 mm; in true myopia, this length exceeds the normal range). As a result, parallel light rays entering the eye focus in front of the retina instead of on it, causing permanent vision loss. Currently, there is no medical method to “shorten” an elongated eye axis, so true myopia is irreversible. However, scientific measures can control the progression of myopia and prevent it from developing into high myopia (myopia degree exceeding 600 degrees).
Control and Vision Protection Methods for True Myopia:
- Wear appropriate corrective eyewear: This is the most basic and necessary measure, including eyeglasses and orthokeratology lenses (OK lenses). For eyeglasses, regular refraction checks are required (every 3-6 months for adolescents, every 1-2 years for adults) to ensure the prescription matches. OK lenses are suitable for adolescents over 8 years old with rapidly progressing myopia. They must be fitted in professional ophthalmic institutions. By wearing them at night, the cornea shape is temporarily changed, allowing daytime vision without glasses while effectively slowing axial elongation.
- Medication-assisted control: Under a doctor’s guidance, use low-concentration atropine eye drops (e.g., 0.01% atropine sulfate eye drops). Clinical studies have shown that these can effectively slow the progression of myopia in adolescents. However, regular rechecks of intraocular pressure and vision are necessary.
- Increase outdoor activity time: Ensure at least 2 hours of outdoor activity daily. Sufficient natural light stimulates the retina to release dopamine, which helps inhibit axial elongation. This is a widely recognized effective method for preventing and controlling myopia.
- Avoid bad eye habits: Do not read or use mobile phones in dim light; do not use electronic devices while lying down or walking. Maintain a correct reading/writing posture (keep the eyes about 33 cm from the book, the chest about one fist away from the edge of the desk, and the fingers holding the pen about 3 cm from the nib).
II. Daily Eye Care: A Long-Term Commitment for Both Pseudomyopia and True Myopia
Whether recovering from pseudomyopia or controlling true myopia, daily eye care habits are crucial. The following methods are suitable for everyone and help maintain good vision:
1. Optimize the Eye-Use Environment
- Ensure adequate lighting: When reading or working, use soft natural light or eye-protection desk lamps. Avoid excessively bright or dim light (desk lamps are recommended to have a warm white light of around 4000K and an illuminance of over 300 lux).
- Adjust electronic device settings: Set the brightness of mobile phones and computer screens to match the ambient light; adjust the screen color temperature to warm tones (to reduce blue light damage). Keep the top of the screen at or slightly below eye level (to avoid neck and eye fatigue from looking up).
2. Supplement Nutrients for Eye Health
- Eat more foods rich in vitamins A, C, E, and lutein: Examples include carrots, spinach, broccoli, blueberries, egg yolks, and nuts. These nutrients protect the retina and relieve eye fatigue (e.g., lutein is a key component of the retinal macula, filtering blue light and reducing light damage).
- Limit sugar intake: Excessive sugar consumption may cause abnormal axial development and accelerate myopia progression. Therefore, reduce the intake of candies, beverages, pastries, and other sugary foods.
3. Conduct Regular Vision Checks
- Adolescents: Due to rapid axial development, vision checks are recommended every 3-6 months to detect myopia progression early and adjust the control plan.
- Adults: If myopia is stable, checks can be done every 1-2 years. If sudden vision loss, distorted vision, or eye pain occurs, seek medical attention immediately to rule out fundus lesions or other issues.
III. Common Misconceptions: These “Recovery Methods” Are Unreliable
Many people fall into misunderstandings when it comes to myopia recovery, blindly trying unproven methods that not only fail to restore vision but may also harm the eyes:
- Misconception 1: “Myopia treatment devices can cure myopia.” Most myopia treatment devices on the market only relieve eye fatigue. They cannot change axial length and have no therapeutic effect on true myopia.
- Misconception 2: “Not wearing glasses will gradually reduce myopia degree.” Not wearing properly fitted glasses causes the eyes to remain in a state of fatigue for a long time, which instead accelerates the progression of myopia.
- Misconception 3: “Laser surgery can reverse myopia.” Laser surgeries (e.g., SMILE, FS-LASIK) correct vision by changing the cornea shape, allowing patients to stop wearing glasses. However, they do not “reverse” myopia (the eye axis length remains unchanged). Additionally, laser surgery has strict eligibility criteria (e.g., being over 18 years old, having stable myopia for at least 2 years) and must be chosen after a doctor’s evaluation.
Conclusion
The recovery and control of myopia is a long-term process, with the key being “early detection, early diagnosis, and early intervention.” Pseudomyopia can be reversed through scientific relaxation and care. Although true myopia cannot be cured, its progression can be effectively slowed with proper correction and eye care methods, preventing serious complications. Instead of blindly seeking “quick recovery” remedies, start developing good eye habits and conducting regular vision checks now to keep your eyes healthy.
