Causes of Double Vision in Elderly

Causes for double vision in older adults.

Double vision, medically known as diplopia, is a visual condition where a person sees two images of a single object instead of one. While double images in vision can affect people of all ages, it is more common among the elderly due to various age-related factors.

Understanding the causes of double vision in elderly is essential for early diagnosis and appropriate treatment. In this blog post, we will explore some of the primary reasons why double vision can occur in older individuals.

What are the Possible Causes of Double Vision in Elderly?

Refractive Errors

Refractive errors, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, are common vision problems that can lead to causes of diplopia. In the elderly, changes in the eye’s lens and cornea can exacerbate these conditions. These age-related changes can make it difficult for the eyes to focus properly, resulting in double vision when trying to see objects at different distances.


Cataracts are a common eye condition that occurs as a person ages. They involve the clouding of the eye’s natural lens, which can cause visual disturbances, including double vision. As cataracts progress, they can create multiple focal points in the eye, leading to double vision or ghosting of images.

Diabetes and Diabetic Retinopathy

Diabetes is a chronic condition that affects the body’s ability to regulate blood sugar levels. Over time, uncontrolled diabetes can lead to diabetic retinopathy, a serious eye complication. Diabetic retinopathy damages the blood vessels in the retina, leading to vision problems, including double vision, blurred vision, and vision loss. Elderly individuals with diabetes should be especially vigilant about their eye health and have regular eye exams to monitor for diabetic retinopathy.

Muscle Weaknesses

The muscles that control eye movement play a crucial role in maintaining binocular vision (the ability to see with both eyes simultaneously). As individuals age, these muscles can weaken, leading to misalignment of the eyes and binocular double vision.

Conditions such as strabismus, cranial nerve palsies, or thyroid eye disease can also affect eye muscle function and exacerbate causes of diplopia in the elderly.

Neurological Conditions

Certain neurological conditions become more prevalent in the elderly and can contribute to double vision. Stroke, multiple sclerosis (MS), and brain tumors are examples of conditions that can affect the nerves responsible for controlling eye movements and visual processing. When these nerves are damaged or compromised, double vision can result.

Medication Side Effects

Many elderly individuals take multiple medications to manage various health conditions. Some medications, particularly those that affect the nervous system or the eyes, can have side effects that lead to double vision. It is essential for seniors to be aware of potential side effects and consult their healthcare providers if they experience any visual disturbances.

Age-related macular degeneration is a progressive eye disease that primarily affects older adults. It damages the macula, the central part of the retina responsible for sharp, central vision. While AMD typically leads to central vision loss rather than double vision, advanced stages of the disease can cause visual distortions that may be perceived as double vision.

Managing Double Vision at 80 With AmblyoPlay

We asked our elderly user, Dan, how AmblyoPlay helped him in managing double vision

”An error by a surgeon during cataract surgery caused me to be afflicted with double vision.  As time went by, the double vision got worse and I decided to create an attempt at a visual exercise application, since I am a software engineer. When I told my son Erik what I was thinking of doing, he began researching existing visual therapy applications, and found online references to AmblyoPlay.”


Double vision in the elderly can result from a variety of causes, including refractive errors, cataracts, diabetic retinopathy, muscle weakness, neurological conditions, medication side effects, and age-related macular degeneration.

It is crucial for older individuals experiencing double vision to seek prompt medical evaluation to identify the underlying cause and receive appropriate treatment. Early intervention can help improve the quality of life for seniors and enable them to enjoy better visual health in their golden years.

Regular eye examinations, double vision test, and open communication with healthcare providers are essential steps in addressing and managing double vision in the elderly, particularly for those with diabetes and diabetic retinopathy.

Frequently Asked Questions

Why is double vision more common among older adults?

Double vision becomes more common among the elderly due to age-related changes in the eye and related structures. These changes can affect the alignment of the eyes, the clarity of vision, and the functioning of the eye muscles, all of which can contribute to the occurrence of double vision.

What are the common causes of double vision?

Common causes of double vision in older adults include refractive errors (nearsightedness, farsightedness, astigmatism), cataracts, muscle weakness affecting eye alignment, neurological conditions, medication side effects, age-related macular degeneration (AMD), and diabetic retinopathy.

Can neurological conditions like stroke and multiple sclerosis cause double vision in older individuals?

Yes, neurological conditions such as stroke and multiple sclerosis (MS) can disrupt the nerves and pathways responsible for controlling eye movements. This disruption can lead to misalignment of the eyes and double vision in older individuals affected by these conditions.

How does diabetes contribute to double vision in the elderly, and what is diabetic retinopathy?

Diabetes can lead to double vision in the elderly through a condition known as diabetic retinopathy. High blood sugar levels can damage the blood vessels in the retina, leading to swelling and bleeding. As a result, the retina’s ability to process visual information is compromised, causing visual disturbances, including double vision. Diabetic retinopathy is a serious complication of diabetes that affects the eyes.

Why Do We Suggest a Minimum Time of 6 Months for Success?

Based on the data from over 15,000 patients using AmblyoPlay, improvements start within 4 months, while optimal results take anywhere between 6-18 months on average. The duration of required training depends on the patient’s age, the severity of the problem, accompanying diseases, and adherence to the training program.
