Association Between Myopia and Mental Health in United States Adults: A population-based analysis of 2023 National Health Interview Survey Data
This 2023 NHIS-based cross-sectional study reveals that United States adults with self-reported myopia have significantly higher odds of anxiety and depression diagnoses, as well as specific treatment-related and sociodemographic factors, underscoring the need for integrated and equity-oriented mental health and vision care approaches.

Imagine your eyes are like high-definition cameras, constantly snapping pictures of the world. Sometimes, the lens of that camera gets a little too curved, making distant objects look blurry. This condition is called myopia (or nearsightedness), and it's the most common vision issue on the planet. Now, imagine your brain is a busy control center that also manages your mood, handling feelings like worry (anxiety) and sadness (depression). Scientists have long wondered if these two systems—the camera and the control center—are secretly texting each other. Does a blurry world make you feel anxious? Or does a stressed-out brain somehow mess with your eyes? It's a bit like asking if a cloudy sky causes the camera to break, or if a broken camera makes the sky look cloudy. Understanding this link matters because if they are connected, treating one might help the other, or at least help doctors understand why some people struggle with both.
This paper is like a giant detective story that looked at data from over 29,000 adults in the United States to see if there really is a connection between having myopia and having mental health challenges. The researchers used a massive survey called the National Health Interview Survey, which is like a giant snapshot of the country's health. They didn't just ask, "Do you have myopia?" and "Are you sad?" They dug deeper, looking at how often people felt anxious, how severe their feelings were, whether they were taking medication, and if they were seeing a therapist. They also checked out who these people were—their age, gender, where they lived, and whether they had health insurance.
Here is what the detectives found: There is definitely a link. Adults who reported having myopia were more likely to also report having been diagnosed with anxiety or depression. It's not a tiny connection, either. People with an anxiety diagnosis had about 1.48 times higher odds of reporting myopia, and those with a depression diagnosis had about 1.43 times higher odds. But the story gets more interesting when you look at the details.
The study suggests that how often you feel these emotions matters more than how intense they are. For anxiety, the more frequently someone felt worried or nervous (like daily or weekly), the higher their odds of having myopia. It's like a drumbeat; the constant rhythm seems to line up with the vision issue. However, for depression, the "loudness" of the sadness (severity) didn't seem to change the odds of having myopia, but the frequency of feeling depressed did.
The researchers also looked at how people were treating these feelings. They found that people taking medication for anxiety or depression were more likely to have myopia. Interestingly, people who were not seeing a therapist or getting counseling were also more likely to have myopia compared to those who were. This doesn't mean the medicine causes the blurry vision or that skipping therapy makes your eyes worse; it just means these groups tend to overlap. The authors suggest this might be because the relationship goes both ways, or because shared factors like stress or lifestyle habits affect both the eyes and the mind.
The paper also ruled out some ideas. It found that while anxiety severity (how bad the anxiety feels) was linked to myopia in the first look at the data, that link disappeared when they adjusted for other factors like age and income. Similarly, the severity of depression didn't show a strong, consistent link to myopia once other details were taken into account. This suggests that simply feeling "very" anxious or sad isn't the key; it might be the constant presence of the condition or the frequency of symptoms that matters more.
Finally, the study highlighted that who you are matters a lot. Women and people of Asian descent were more likely to report having myopia. On the flip side, people who were not citizens of the US or who didn't have health insurance were much less likely to report having myopia. The authors are careful to say this probably isn't because non-citizens or uninsured people have healthier eyes. Instead, it likely means they have less access to eye doctors to get diagnosed, or they might not realize they need glasses. It's like having a broken camera but never taking it to a repair shop, so you don't know it's broken.
In the end, this paper doesn't prove that anxiety causes myopia or vice versa. It just shows that they often hang out together, especially when anxiety or depression happens frequently. The study suggests that our mental health, our access to care, and our vision are all tangled up in a complex web. It's a reminder that taking care of your eyes and taking care of your mind might need to happen at the same time, and that how often we feel certain emotions might be a bigger clue than how strong those feelings are.
