Yes, anxiety can impact your eyes and vision. During stress or anxiety, the body’s “fight or flight” response triggers hormone release, causing pupil dilation and increased sensitivity to light. This can lead to eye strain, twitching, blurred vision, dry or overly watery eyes, and even tunnel vision.
Persistent anxiety may heighten these symptoms, making it harder for your vision to recover. High stress can also increase eye pressure, potentially raising the risk of conditions like glaucoma, especially in students facing exam-related anxiety. Relaxation techniques, such as deep breathing and meditation, can help alleviate eye strain, though ongoing symptoms should be checked by a GP.
The Times have recently discussed the negative impact of taking multiple exams over a long period of time on students’ vision and how this could even cause the eye condition known as glaucoma. It is important to be aware of the symptoms your eyes may be showing due to stress during moments in your life when you are feeling particularly overwhelmed and under pressure.
How Can Stress Affect Your Eyes And Vision?

Whilst we all experience stress during our lifetimes, but constant anxiety can take its toll on our eyes, as well as the rest of our body.
When you are feeling stressed or anxious your body will begin to activate its stress response, this is what scientists call ‘fight or flight’ mode. As this happens your body will start producing hormones like adrenaline, which will then speed up your heart rate, begin to stimulate your nervous system and heighten your senses. As your eyes are sensory organs, they are directly impacted by stress.
In a state of anxiety your brain will send signals that will cause your pupils to dilate. This enables more light to get into your eyes, which as a result is meant to allow you to see potential dangers more quickly. Whilst it is great that our bodies respond in this way when there is a genuine danger in front of us, it often isn’t helpful for the day to day problems that inflict this stress response. In addition, being stressed can often leave you feeling tense, and that can mean your eyes are too, as the muscles around them can tighten, causing soreness and twitching.
What Are The Symptoms Of High Stress Affecting Your Eyes?

- Eye twitching
- Sensitivity to light
- Eye strain
- Eye floaters
- Difficulty to focus/blurred vision
- Tunnel vision
- Overly wet or dry eyes
If you are not stressed on a frequent basis then your vision should return back to normal, undamaged. However if you find yourself stressed out for a long time, these changes to your sight can become harmful, as it becomes harder for your vision to recover. For example the constant dilation can cause your eye to become particularly sensitive to light, and become seriously strained as a result.
How Does Exam Stress Affect Students Eyes?
With students facing coursework deadlines and exams, their stress levels are likely to be high. With anxiety causing an increased pressure in the eye, concern has been raised around students chances of developing the complex eye disease, glaucoma. Although eye pressure doesn’t alone cause glaucoma, the Glaucoma Research Foundation considers it a significant risk factor, further advising that individuals diagnosed with high eye pressure should have regular eye tests to check for the symptoms of the onset of this disease.
