Vision Blurring? Why Myopia Worsens & Medically Approved Steps

If you've noticed that distant objects look blurry or that your glasses prescription keeps getting stronger, you may be experiencing myopia, also known as nearsightedness. Myopia is one of the most common vision conditions worldwide, and it is becoming more common in both children and adults.

While myopia can often be corrected with glasses or contact lenses, it is not something to ignore—especially if it continues to worsen. In some cases, progressive or severe myopia can increase the risk of serious eye problems later in life.

Let's break down why myopia worsens, what that means for your health, and what medically approved steps can help protect your vision.

What Is Myopia?

Myopia occurs when the eye grows too long from front to back or when the cornea (the clear front surface of the eye) is too curved. This causes light entering the eye to focus in front of the retina rather than directly on it.

The result?

• Close objects appear clear
• Distant objects look blurry
• You may squint to see road signs or faces far away

Myopia often begins in childhood and may progress during the teenage years. For some people, it stabilizes in early adulthood. For others, it continues to worsen.

Why Does Myopia Worsen?

There are several medically recognized reasons why myopia progresses.

1. Eye Growth During Childhood

The most common reason myopia worsens is natural eye growth. As children grow taller, their eyes also grow. If the eyeball becomes too long, nearsightedness increases.

This is why:

• Myopia often starts between ages 6 and 12
• Prescriptions may change every year during growth spurts
• Teen years are a common time for progression

2. Genetics

If one or both parents have myopia, the risk of a child developing it increases significantly. Children with two myopic parents are at especially higher risk.

Genetics do not guarantee severe myopia, but they increase susceptibility.

3. Too Much Near Work

Research shows that extended close-up tasks may contribute to worsening myopia, especially in children. Examples include:

• Long hours on smartphones or tablets
• Reading at very close distances
• Prolonged computer use
• Studying without breaks

Near work itself does not "damage" the eyes, but sustained focusing up close without breaks may influence eye growth in children.

4. Not Enough Outdoor Time

Multiple large studies show that children who spend more time outdoors have a lower risk of developing or worsening myopia.

Natural sunlight exposure appears to help regulate healthy eye growth. Experts believe light stimulation plays a protective role.

5. High or Severe Myopia

In some individuals, myopia continues progressing into adulthood. When prescriptions exceed -6.00 diopters, this is typically considered severe myopia (also called high myopia).

Severe myopia increases the risk of:

• Retinal detachment
• Glaucoma
• Cataracts at a younger age
• Myopic macular degeneration

If you're experiencing symptoms like rapidly worsening vision or have concerns about high myopia, it's helpful to start with Ubie's free AI-powered Severe Myopia symptom checker to assess your risk before consulting with an eye care professional.

Signs That Myopia May Be Getting Worse

You may notice:

• Blurry road signs while driving
• Difficulty seeing the board in class
• Frequent squinting
• Eye strain or headaches
• Needing stronger glasses more often

In severe cases, warning signs that require urgent medical attention include:

• Sudden flashes of light
• A curtain-like shadow in your vision
• Sudden increase in floaters
• Sudden vision loss

These symptoms could signal retinal detachment and require immediate emergency care.

Medically Approved Ways to Slow Myopia Progression

The good news is that modern eye care offers evidence-based strategies to slow myopia progression, particularly in children.

1. Prescription Glasses or Contact Lenses

Standard single-vision glasses correct blurry vision but do not necessarily slow progression.

However, special designs may help control worsening:

• Myopia control lenses
• Multifocal contact lenses
• Orthokeratology (overnight corneal reshaping lenses)

These options should only be prescribed and monitored by an eye care professional.

2. Low-Dose Atropine Eye Drops

Low-dose atropine drops have been shown in clinical studies to slow myopia progression in children.

Key points:

• Used once daily
• Typically well tolerated
• Requires prescription and monitoring
• Not appropriate for everyone

This treatment is increasingly recommended for children with rapidly worsening myopia.

3. Increased Outdoor Time

Encouraging children to spend at least 1.5 to 2 hours outdoors daily has been shown to reduce the risk of developing and worsening myopia.

Simple habits include:

• Playing outside after school
• Outdoor sports
• Family walks

This is one of the safest and most accessible preventive strategies.

4. The 20-20-20 Rule

To reduce eye strain during near work:

• Every 20 minutes
• Look at something 20 feet away
• For at least 20 seconds

This does not cure myopia but may reduce strain and support healthy habits.

5. Proper Reading Distance

Encourage children and adults to:

• Hold books about 14–16 inches away
• Avoid reading in very dim light
• Sit upright instead of lying down while using devices

Small adjustments can support eye comfort and reduce strain.

When Myopia Becomes Severe

Severe or high myopia is not just about stronger glasses. It involves structural changes in the eye that increase long-term risk.

Over time, excessive eye elongation can stretch and thin the retina. This is why regular monitoring is critical.

People with severe myopia should:

• Have comprehensive dilated eye exams annually (or as recommended)
• Monitor for new visual symptoms
• Follow medical advice closely

Early detection of complications can prevent permanent vision loss.

---

Can Myopia Be Reversed?

Currently, there is no medically proven way to reverse myopia naturally once it develops.

Laser vision correction (such as LASIK or PRK) can reduce dependence on glasses in eligible adults, but:

• It does not cure the underlying eye shape
• It does not eliminate long-term risks of severe myopia
• It requires thorough medical evaluation

Children and teenagers are generally not candidates for refractive surgery.

Reducing Anxiety While Staying Realistic

It's important to approach myopia calmly but responsibly.

For most people:

• Myopia is manageable
• Vision correction is highly effective
• Serious complications are uncommon with proper care

However, ignoring worsening symptoms or skipping regular eye exams can increase long-term risk—especially with severe myopia.

The key is awareness, not fear.

When to Speak to a Doctor

You should speak to an eye doctor promptly if you experience:

• Rapid prescription changes
• Sudden vision loss
• Light flashes or floaters
• Distorted or wavy vision
• Eye pain

If you or your child have progressive myopia, ask about:

• Myopia control treatments
• Atropine therapy
• Specialized lenses
• Monitoring frequency

If any symptoms feel severe, sudden, or potentially vision-threatening, seek urgent medical care immediately.

Final Thoughts

Myopia is common, but progression is not something to ignore. Understanding why myopia worsens allows you to take practical, medically supported steps to protect your vision.

The most effective strategies include:

• Regular comprehensive eye exams
• Increasing outdoor time (especially for children)
• Considering myopia control treatments
• Monitoring for warning signs of complications
