Does Dry Eye Cause Blurry Vision?

Blurry vision is a general complaint from those with dry eye syndrome. Several reasons include screen time, lifestyle, diet and nutrition, and the possibility of severe and other health conditions.


To address emergency matters first, if the blurry vision comes on suddenly and is accompanied by other sudden changes such as slurred speech, lack of muscle tone on half of the body, and severe headache, seek immediate attention as the person may be having a stroke.


Blurry vision and dry eye syndrome can also be due to certain autoimmune conditions, such as thyroid eye disease, Sjögren's, and rheumatoid arthritis. If you suspect such conditions, work with your healthcare provider to get a proper diagnosis.


Specific activities involving the prolonged use of screens can lead to blurry vision and dry eye syndrome. With screens, people tend to slow their blink rate. When the blink rate slows, the eyes can suffer from dehydration. Excessive use of the eyes can also lead to blurry vision. With this condition, lifestyle changes and eye drops have alleviated the symptoms.


For others, contact lens use can irritate and dry the eyes and lend itself to blurry vision, often due to debris buildup. You may need to work with your provider to optimize your lenses and eye drops.

For some people, nutritional supplements such as vitamin A and omega-3 fatty acids can moisten and strengthen the eyes. Please monitor your levels to avoid overuse and potentially severe side effects if you take vitamin A.


In the anatomy of the eye, the tear film is made of three layers. If any of these layers are insufficient, it will affect the integrity of the tear film. An insufficient tear film can lead to blurry vision when the tear film is compromised because it affects the refracting surface of the cornea.


There are multiple causes, so it's wise to catch the condition early. Knowing the reason can help with individualized treatment.
