Stress is the body's natural response to a situation perceived as threatening or challenging. While it is normal and sometimes even useful in small doses, prolonged stress can have negative effects on the body.
When the body and eyes are connected
Our eyes are not isolated from the rest of the body: they are connected to the nervous system and strongly influenced by our emotions and overall health. When we experience intense stress, the body releases hormones such as cortisol and adrenaline. These substances can cause temporary changes in how the eyes function.
Effects of stress on vision
Here are some visual symptoms that stress can cause:
- Blurred or cloudy vision: Changes in muscle tension and eye pressure can interfere with sharp vision.
- Dry eyes: Stress can reduce tear production, making the eyes feel dry and uncomfortable.
- Eye tics (fasciculations): These small, involuntary spasms of the eyelid are often linked to fatigue and stress.
- Increased sensitivity to light: Some people become more sensitive to light contrasts during periods of anxiety.
- Ophthalmic migraine: Stress can trigger migraines with visual aura, including flashes of light or blurred areas in the field of vision.
Chronic stress and eye health
In the long term, persistent stress can contribute to the worsening of certain eye diseases. For example, it is associated with increased intraocular pressure, which can be a risk factor for glaucoma. Stress can also amplify the perception of symptoms related to dry eye or certain retinal conditions.
How can you protect your eyes during times of stress?
The good news is that simple steps can help reduce these effects:
- Take regular breaks from screens to rest your eyes.
- Practice relaxation techniques such as deep breathing, meditation, or yoga.
- Get enough sleep, as fatigue exacerbates stress-related visual disturbances.
- Stay well hydrated and eat a balanced diet rich in antioxidants that are beneficial to eye health.
- Consult an eye care professional if you notice persistent changes in your vision.
Yes, stress can affect your vision, both temporarily and in the long term if it becomes chronic. Listening to your body, taking care of your mental well-being, and seeing your optometrist regularly are effective ways to preserve your visual health.
