Decreased vision due to fatigue: causes and solutions
About the Symptom
Decreased vision during fatigue is a common symptom that can occur in people who spend a lot of time in front of computer, smartphone, and television screens. In today’s reality, where work and personal life are often tied to prolonged screen time, this condition is becoming increasingly relevant. Eye fatigue, or asthenopia, manifests as blurriness, lack of clarity, as well as sensations of heaviness, burning, or tingling in the eyes. These symptoms can significantly affect the quality of life and work performance.
When we get tired, the muscles responsible for focusing vision begin to fatigue and cannot work as effectively as before. This leads to a deterioration in visual acuity and increased sensitivity to light. It is important to note that decreased vision due to fatigue is usually a temporary phenomenon, but it should not be ignored. Regular rest, adherence to hygiene standards when working with screens, and taking regular breaks will help restore vision and prevent more serious eye diseases in the future.
Diseases
Decreased vision due to fatigue may be associated with various diseases that affect the visual system and the overall health of the body. Often, fatigue symptoms such as blurred vision, headaches, and discomfort in the eyes may indicate the presence of more serious vision problems. For example, prolonged visual strain without breaks can lead to the development of Computer Vision Syndrome (CVS), which manifests not only as decreased visual acuity but also as other unpleasant sensations such as dryness and burning in the eyes.
Additionally, some systemic diseases may also cause a deterioration in vision against the backdrop of fatigue. This may be related to changes in blood circulation, sugar levels, or blood pressure, which negatively affect the condition of the eyes and visual function. If decreased vision is accompanied by other symptoms, it is worth paying attention to one’s health and consulting a specialist to rule out more serious problems.

- Hyperopia (farsightedness)
Diagnosis
The diagnosis of vision deterioration due to fatigue begins with a comprehensive examination of the patient’s eye health. The ophthalmologist conducts a thorough examination, which allows for identifying the causes of vision impairment associated with fatigue. Key points of the diagnosis include determining visual acuity, checking refraction, as well as assessing the condition of the tear film and the presence of signs of dry eye syndrome, which is often related to prolonged computer use or other visual stresses.
In addition, if necessary, further studies may be assigned, including optical coherence tomography (OCT) and perimetry to assess the functional state of the retina and the visual field. Timely diagnosis allows not only to identify factors contributing to the deterioration of vision but also to suggest optimal correction and prevention methods aimed at improving the patient’s quality of life.
- Measurement of visual acuity
- Refraction measurement
- Corneal topography
- Optical coherence tomography (OCT)
- Perimetry
- Testing for dry eye syndrome
- Color perception examination
Which doctor to consult
When experiencing a decrease in vision caused by fatigue, it is important not to ignore this symptom. The first specialist to consult is an ophthalmologist. This doctor performs a comprehensive eye examination, including checking visual acuity, the condition of the cornea and retina, allowing for the identification of the causes of decreased vision. Tired eye muscles can be one of the reasons for temporary deterioration, but only a qualified ophthalmologist can accurately diagnose and suggest effective treatment methods.
Additionally, depending on the results of the examination, a consultation with other doctors may be necessary. For example, if decreased vision is accompanied by headaches or coordination problems, it is recommended to consult a neurologist. This specialist will help rule out possible neurological pathologies that may contribute to worsening vision. Don’t forget to also consult a therapist to rule out general conditions, such as diabetes or hypertension, that can cause a decline in visual functions.

Types of Vision Decrease Due to Fatigue
A decrease in vision due to fatigue can manifest in various forms and degrees. One of the most common types is temporary deterioration of visual clarity, which occurs during prolonged computer work or reading. In such cases, patients may report blurriness of images, difficulties in focusing on text or small details.
Another type is dry eye syndrome, which often accompanies fatigue. With insufficient blinking or prolonged time spent in an air-conditioned or heated room, the tear film loses its stability. This leads to discomfort, itching, and a decline in visual quality. In most cases, symptoms may resolve after rest, but if they become chronic, it is important to consult a specialist.
- Temporary deterioration of visual clarity
- Dry eye syndrome
- Asthenopic phenomena (headaches, eye strain)
- Infrequent blinking and its effect on vision
Causes of Vision Decrease Due to Fatigue
The decrease in vision when fatigued can be caused by various factors related to both the physical and emotional state of a person. One of the most common reasons is prolonged work at the computer or reading, which leads to eye muscle strain. During this, the eyes may experience confusion, resulting in symptoms such as blurred vision, burning, or stinging. It is important to remember that prolonged visual strain without breaks significantly increases the risk of these unpleasant sensations.
It is also worth noting that lack of sleep and high levels of stress negatively affect the overall condition of the body, including eye health. Fatigue can lead to a decrease in the quality of tear fluid and irritation of the conjunctiva, which increases discomfort in the eyes. Against the backdrop of constant fatigue, vision may deteriorate, resulting in the need for regular breaks and the proper organization of the workspace to maintain healthy vision.
- Prolonged computer work
- Lack of sleep
- Stressful situations
- Poor organization of the workspace
- Inadequate vision correction
Common Related Pathologies
Decreased vision due to fatigue may be a symptom of various pathologies that require the attention of specialists. Often, this decrease is related to a condition known as asthenopia, which can develop as a result of prolonged computer work or reading text at close range. The eyes begin to tire, leading to a decline in vision, the brain does not receive sufficient information, and the patient feels discomfort. This condition is associated with the overstrain of the visual organs and may be accompanied by headaches, burning, or dryness of the eyes.
Additionally, decreased vision may be associated with more serious diseases, such as hypertension or diabetes, which, in turn, affect eye health. These diseases can lead to retinopathy or loss of visual function, especially if blood sugar and blood pressure levels are not controlled. Therefore, it is important not to ignore the deterioration of vision due to fatigue, and in case of persistent discomfort, to consult a doctor to rule out serious diseases.
