Amblyopia (Lazy Eye) and Adults

Although amblyopia is typically associated with children, treatment for amblyopia in adults is both possible and effective.

Even though amblyopia is generally considered a disorder of the pediatric population, we must not forget that, if left untreated, it will continue to impact one’s quality of life throughout their lives. According to studies, 1-3% of adults have a certain degree of amblyopia, mostly resulting from untreated or inadequately treated anisometropia or strabismus in their childhood.

In some, the degree of amblyopia is negligible and does not importantly interfere with the quality of vision, but in others it can be pronounced to the point of basically having only one functioning eye. Whilst certain therapeutic options (vision training, perceptual learning) for adults do exist, they are nowhere near as effective as in children. 

What is Lazy Eye?

Amblyopia, commonly known as “lazy eye,” is a visual disorder that affects approximately 2-3% of the population. It typically develops in childhood when the brain favors one eye over the other, leading to reduced vision in the weaker eye. Therefore, eyes do not work simultaneously, as a team.

It is important to note that amblyopia is not simply an eye problem—it is a brain-related issue. The brain actively shuts down the image from the weaker eye, limiting the visual information it processes from that eye.

Many people confuse lazy eye with strabismus (crossed eyes), a condition in which one eye is misaligned. While strabismus can lead to amblyopia, a person can have amblyopia without visible signs of eye misalignment.

While amblyopia is often diagnosed and treated during childhood, there is a growing awareness of adult amblyopia and its impact on the quality of life.

What Causes Lazy Eye in Adults

Amblyopia in adults typically originates in childhood, though it may remain undiagnosed until later in life. The main causes include:

1. Strabismic Amblyopia: If one eye is misaligned, the brain may ignore the input from that eye to avoid double vision.

2. Refractive Amblyopia: When there is a large difference in refractive errors (nearsightedness, farsightedness, or astigmatism) between the two eyes, the brain tends to rely on the clearer eye and suppresses the other.

3. Deprivation Amblyopia: This occurs when there is a physical obstruction that prevents proper visual input from reaching one eye during early development, such as a cataract.

4. Injury or Disease: Injury or conditions like cataracts in adulthood can cause or exacerbate amblyopia by impairing the vision in one eye and leading the brain to favor the stronger eye.

Misconceptions About Treating Lazy Eye in Adults

For years, it was believed that amblyopia in adults treatment was ineffective due to limited brain plasticity past childhood. It was thought that if amblyopia wasn’t corrected by around age eight, the condition would be permanent. This idea stems from early research in the mid-20th century, particularly from studies on animals that led scientists to conclude that brain plasticity was limited to early childhood.

However, recent studies have shown that this conclusion was incorrect. Brain plasticity—the ability of the brain to change and adapt—exists well beyond childhood, even into adulthood. This means that adults with amblyopia still have the potential to improve their vision with the right treatments.

Lazy Eye Symptoms in Adults

Lazy eye can be subtle and often goes unnoticed until adulthood. Some adults might not even realize they have it until they experience vision difficulties in daily life. Common symptoms include:

• Blurry vision in one eye
• Poor depth perception, which can make activities like driving or playing sports difficult
• Difficulty focusing on detailed tasks
• Eye strain or fatigue, particularly during tasks that require detailed vision like reading or working on a computer
• Difficulty reading or seeing fine print
• Headaches, especially after prolonged use of the eyes
• Squinting or closing one eye when focusing

In cases where amblyopia is caused by strabismus, the misalignment of the eyes may be visible to others.

How can Adult Amblyopia Affect Individuals Quality of Life?

Cases of minor residual amblyopia usually do not cause a significant impact. However, this changes dramatically when the degree of adult amblyopia becomes more apparent.

Apart from experiencing physical or vision symptoms, people will often have to deal with the mental impact as well. Studies show that adults with residual amblyopia may experience various symptoms, ranging from glare to difficulty concentrating.

They sometimes report difficulties in driving, reading, or tasks that require great perception of depth and good visual acuity.

Just as importantly, they are oftentimes extremely worried about the safety and health of their better eye, which can lead to anxiety. Sometimes they also deal with guilt if they had not complied with the treatment in their childhood or simply regret the missed opportunity of having been diagnosed and treated when they were still children. However, let us approach different influences more systematically below.

Visual Impairment and Daily Activities

Adults with amblyopia often experience reduced visual acuity, depth perception, and visual field defects.

These visual impairments can pose challenges in performing everyday tasks such as driving, reading, and recognizing faces. Difficulties in depth perception may affect activities that require accurate distance judgment, like sports or manual work. The impact on these routine activities can lead to frustration, dependency on others, and limitations in personal and professional life.

Self-Esteem and Social Interactions

Living with amblyopia can have a significant impact on an individual’s self-esteem and social interactions. Adults with amblyopia may feel self-conscious about their appearance, particularly if their eyes appear noticeably different.

They might avoid eye contact or feel anxious in social settings, leading to feelings of isolation and potential impacts on personal relationships. The psychological effects of amblyopia can manifest as social anxiety, low self-confidence, and a diminished quality of life.

Occupational Challenges

Amblyopia can also present obstacles in the workplace. Certain professions, such as those requiring precise vision or depth perception, may be more difficult for individuals with amblyopia to pursue. Job opportunities that involve driving, operating machinery, or tasks dependent on accurate visual perception may be limited. These challenges may require individuals to make career choices based on their visual limitations, potentially affecting their overall job satisfaction and financial well-being.

How to Prevent Adult Amblyopia?

What are the causes for lazy eye in adults? Since adult amblyopia is more or less just a sequel of improperly or inadequately addressed amblyopia in one’s childhood, properly treated amblyopia in children is all that we need.

Early diagnosis, properly prescribed treatment, and compliance to the prescribed treatment are key for everyone with amblyopia. However, if you already missed the early treatment, there are still treatment options for adults with lazy eyes.

Can Lazy Eye Be Treated in Adults?

Yes, treatment for amblyopia in adults can be successful! While the ideal time to treat amblyopia is during childhood, there is growing evidence that adults with lazy eye can still improve their vision with treatment. . This belief stems from the idea that the brain can retain some plasticity—the ability to rewire itself—throughout life.

However, treatment in adults tends to take longer, and the extent of improvement varies depending on individual circumstances.

How to Fix Lazy Eye in Adults: Treatment

While amblyopia is commonly treated during childhood, there are emerging treatment options for adults as well. Vision therapy, including eye exercises, optical aids, and patching, can help improve visual acuity and reduce some of the effects of amblyopia.

The effectiveness of treatment varies depending on the individual’s age, severity of amblyopia, and compliance with therapy. Here are some common treatment options for lazy eye in adults:

1. Glasses: For adults with refractive amblyopia, wearing prescription glasses or contact lenses can help equalize the vision in both eyes. Corrective lenses ensure that both eyes are receiving similar visual input, allowing the weaker eye to start “catching up” in terms of focus
   
2. Vision therapy: Vision therapy for adults involves exercises designed to train the brain and eyes to work together more effectively. These therapies can be done under the supervision of a vision specialist and often include activities like focusing exercises, eye-tracking tasks, and perceptual training. Computer programs and virtual reality games have also become popular tools for improving amblyopia.
   
3. Eye patching: This treatment involves placing a patch over the stronger eye for a set period each day to force the brain to use the weaker eye. While eye patching is commonly associated with children, some adults may still benefit from this approach, though it usually requires persistence and professional guidance.
   
4. Lazy eye surgery: For adults whose amblyopia is caused by strabismus, surgery may be necessary to correct the alignment of the eyes. While surgery won’t cure amblyopia on its own, it can help both eyes work together more effectively and improve depth perception. This is typically combined with vision therapy for best results.
   

How Vision Therapy Helps Treat Lazy Eye in Adults?

Have you ever heard that you are too old for vision therapy and to improve your lazy eye (or amblyopia)? Well, studies show that this is not the case and that significant improvement is possible at any age with a correct treatment plan.

The speed of recovery is the fastest for children who are at the peak of their brain plasticity, yet the brain does not lose its ability to retrain completely – it just loses speed! Vision therapy improves various visual skills.

1. Eye Teaming (Binocular Vision)
   Vision therapy improves the ability of both eyes to work together as a team, enabling proper coordination and alignment for clear and comfortable vision. Stereopsis refers to the ability to perceive depth and 3D structure obtained on the basis of visual information. What is more, it is the measure of binocular visual function.
   
2. Eye Focusing: Vision therapy aids in improving the ability to shift focus efficiently between near and far distances. For example, smoothly following the ball in motion. It can address difficulties related to eye accommodation, such as blurred vision or eye strain when transitioning between different viewing distances.
   
3. Eye Tracking (Pursuits): This refers to the ability to smoothly and accurately follow moving objects with the eyes. Vision therapy can help enhance eye tracking skills, which are essential for activities such as reading, sports, and driving.
   
4. Eye-hand Coordination (Spatial Skills): Vision therapy enhances the connection between the visual system and the motor system, improving hand-eye coordination. This skill is crucial for tasks that require precise visual guidance of hand movements.
   
5. Eye fixation: Refers to the act of directing and maintaining visual attention on a specific object or point in space. Furthermore, it is the ability to keep the eyes steady and focused on a particular target or location. Fixation is an essential part of visual perception and allows us to gather detailed information about the object we are looking at.
   
6. Saccadic eye movements: Saccades are rapid, involuntary eye movements that shift the gaze from one point to another. They are quick, ballistic movements that allow the eyes to quickly and accurately move between different objects or points of interest in the visual field.

The Importance of Brain Plasticity in Treating Amblyopia

The key to treating amblyopia in adults lies in the brain’s plasticity. While it’s true that brain plasticity is more robust in children, adults still retain the ability to rewire their neural pathways. This ability is the foundation for treatments like vision therapy, which aim to retrain the brain’s visual system.

Untreated Lazy Eye in Adults

Untreated lazy eye in adults can lead to long-term visual impairment and complications. When amblyopia is not addressed, the brain continues to suppress the input from the weaker eye, resulting in persistently reduced vision.

This can affect depth perception and binocular vision, making daily tasks such as driving, reading, or engaging in sports challenging. Moreover, untreated amblyopia increases the risk of total vision loss if the stronger eye becomes injured or develops a condition such as cataracts.

AmblyoPlay for Adults

Sumit: ”I highly recommend AmblyoPlay irrespective of age”

Hi, I am 30 years old. I have been using AmblyoPlay for the past 6 months. It’s a really good app. It chooses the games at random and helps you improve your vision for the lazy eye. If practiced daily, you can sense the improvement. Just maintain a good streak and you would see that your gaming performance is improving. Double vision is reducing as well. Highly recommended to anyone who wishes to treat amblyopia irrespective of age. However, it would be great to receive daily, weekly reminders so that one doesn’t skip the practice.

Carol: ”Using AmblyoPlay as an adult has not only improved my vision but also exceeded my expectations in countless ways”

After 11 months, my optician is very impressed & has now prescribed glasses that no longer exclude the weak eye, but use it.
Best of all, as my binocular vision has improved so much reading is easier, I no longer drop as many things, and my eye & neck strain has reduced ….. AND my right eye looks straighter in the socket rather than drifting to the side. He’s now finding out more about Amblyoplay to recommend it to other patients – so hopefully a good result for the Amblyoplay team too.

THANK YOU TO THE AMBLYOPLAY TEAM FOR IMPROVING MY LIFE.
