You’ve probably heard the terms squint eye, cross-eye, and lazy eye but aren’t sure what they mean or when to use them. This is because they are often used interchangeably, but incorrectly. So the confusion between the terms is understandable. 

We’ll go over the causes, symptoms, and treatments of these two conditions in this blog to help you make a clear distinction. By knowing what each one is, you can be mindful of the condition and not be ignorant. 

Let’s start by simply defining the two. 

What Is Squint Eye/Cross-Eye? 

Both these terms describe the same condition which is otherwise known as Strabismus. It is a condition where the eyes do not look in the same direction at the same time. One or both eyes might point upwards, downwards, inwards, or outwards. This can be either continuous or intermittent, but it makes it difficult for the brain to combine images from each eye to form a single image.

What Is a Lazy Eye?

When one of your eyes’ vision does not develop properly, it is referred to as a lazy eye. Amblyopia is a term used by doctors to describe this condition. If you don’t get treatment, your brain will learn to ignore the image from your weaker eye. This could result in long-term vision issues.
