What is vision like with strabismus?

Answered by John Hunt

Having strabismus can greatly affect a person’s vision. When someone has strabismus, their eyes are not able to focus together on the same object. This means that each eye is sending a different picture to the brain. As a result, the brain may perceive two separate images, leading to double vision. Alternatively, the object being looked at may appear blurry.

Imagine trying to look at a book on a table with both eyes but not being able to align them properly. One eye may be looking directly at the book, while the other eye is slightly turned inward or outward. This misalignment causes the brain to receive conflicting information from the eyes. The brain then struggles to merge the two different images into one coherent picture.

Double vision is a common experience for individuals with strabismus. It can be quite disorienting and make it challenging to navigate the world. For instance, while reading a sentence, one eye may see the words in one position, while the other eye sees them in a slightly different position. This can make it difficult to comprehend the text and can lead to slower reading speeds.

In addition to double vision, strabismus can also cause blurred vision. When the eyes are not properly aligned, the brain may struggle to process the visual information it receives. This can result in a blurry or hazy appearance of objects. Imagine trying to read a street sign or recognize someone’s face but everything appears fuzzy or out of focus. This blurriness can make it challenging to see details clearly and can impact daily activities such as reading, writing, and recognizing faces.

It is worth mentioning that the severity of vision problems can vary among individuals with strabismus. Some people may experience intermittent strabismus, where the misalignment occurs only at certain times or under specific conditions. Others may have constant misalignment, leading to persistent double vision or blurred vision.

It is important to note that the brain can sometimes adapt to the misalignment caused by strabismus. In some cases, the brain may suppress or ignore the image from one eye to avoid perceiving double vision. This suppression can result in a condition called amblyopia or “lazy eye.” The brain prioritizes the visual input from the stronger eye and may neglect the visual development of the weaker eye. As a result, the weaker eye may not develop normal visual acuity, leading to reduced vision in that eye.

Living with strabismus can be challenging, especially when it comes to visual perception. Tasks that many people take for granted, such as reading, playing sports, or even walking in a crowded area, can become more difficult. However, with proper diagnosis and treatment, including vision therapy, corrective lenses, or surgery, it is possible to improve visual alignment and alleviate the associated vision problems.

Personal experiences may vary, and it is always advisable to consult with an ophthalmologist or optometrist for a comprehensive evaluation and appropriate treatment options tailored to individual needs.
