Myopia, or nearsightedness, is one of the most common vision issues worldwide. For most people, it’s a manageable condition corrected with glasses, contact lenses, or refractive surgery. However, in severe cases, myopia can lead to complications that significantly increase the risk of vision loss or blindness.
At Eye Sea Davis Optometry, we’re dedicated to educating our patients in Davis, California about the risks of myopia and how to manage it effectively. In this blog, we’ll explore whether myopia can cause blindness, the risks associated with high myopia, and how to protect your vision.
Understanding Myopia
Myopia occurs when the eye is too long or the cornea is too curved, causing light to focus in front of the retina instead of directly on it. This results in blurry distance vision while close-up objects remain clear.
Key Facts About Myopia:
- It typically develops during childhood and may progress into early adulthood.
- Myopia can range from mild to severe (often referred to as high myopia).
While standard myopia isn’t linked to blindness, its more severe form—high myopia—can lead to complications that threaten vision.
Can Myopia Lead to Blindness?
Mild or Moderate Myopia:
- Rarely causes serious complications. With corrective lenses, most people maintain clear, functional vision throughout their lives.
High Myopia (Severe Myopia):
- Defined as a prescription of -6.00 diopters or higher, high myopia can stretch and thin the retina and other eye structures, increasing the risk of vision-threatening conditions.
Vision-Threatening Risks of High Myopia
- Retinal Detachment
- The stretched retina in highly myopic eyes is more prone to tears or detachment. If untreated, retinal detachment can lead to permanent vision loss.
- Symptoms to Watch For: Sudden flashes of light, new floaters, or a shadow in your peripheral vision.
- Myopic Macular Degeneration (MMD)
- Prolonged stretching of the eye can cause damage to the macula, the central part of the retina responsible for sharp vision.
- MMD can lead to permanent central vision loss if not managed early.
- Glaucoma
- People with high myopia have a greater risk of developing glaucoma, a condition where increased eye pressure damages the optic nerve.
- This damage is irreversible and can lead to blindness if untreated.
- Cataracts
- High myopia increases the likelihood of developing cataracts earlier in life. While treatable with surgery, severe cases can still impact vision.
- Choroidal Neovascularization
- Abnormal blood vessels may grow beneath the retina, leading to bleeding and scarring. This condition requires urgent treatment to prevent further vision loss.
How to Prevent Myopia-Related Vision Loss
While myopia itself can’t be reversed, there are steps you can take to manage it effectively and reduce the risks of complications.
1. Early Detection and Myopia Management
- Regular eye exams, especially for children, are crucial for identifying and controlling myopia progression.
- At Eye Sea Davis Optometry, we offer treatments like Ortho-K lenses and MiSight contact lenses to slow myopia progression in children.
2. Protect the Retina
- Patients with high myopia should undergo regular retinal screenings to catch potential issues early.
3. Practice Healthy Visual Habits
- Limit prolonged screen time and ensure children take breaks during close-up tasks to reduce eye strain.
- Encourage outdoor play, as spending time outside has been shown to slow myopia progression in children.
4. Monitor for Warning Signs
- Pay attention to symptoms like flashes of light, a sudden increase in floaters, or blurred vision, and contact your eye doctor immediately if they occur.
5. Wear UV-Protective Lenses
- Protecting your eyes from UV rays can reduce the risk of additional retinal damage.
When to See an Eye Doctor
If you or a family member have high myopia, it’s essential to schedule regular eye exams. Be proactive about your eye health if you experience:
- Sudden vision changes
- New or worsening floaters
- Flashes of light
- Difficulty seeing fine details
At Eye Sea Davis Optometry, we use advanced diagnostic tools to monitor your eye health and create personalized treatment plans to safeguard your vision.
