More Info

---

Eye fatigue, also known as asthenopia, is a common condition that can manifest through various symptoms, including discomfort, strain, and visual disturbances. Understanding the symptoms, causes, and potential solutions can help manage this condition effectively.


Symptoms of Eye Fatigue
The symptoms of eye fatigue can vary widely among individuals but often include:
1. Discomfort or Pain: This can manifest as a feeling of heaviness or soreness around the eyes.

2. Blurred Vision: Difficulty focusing on objects, especially after prolonged periods of reading or screen time.

3. Dryness or Irritation: A sensation of dryness, often accompanied by redness or a gritty feeling in the eyes.

4. Headaches: Frequent headaches, particularly after extended visual tasks.

5. Sensitivity to Light: Increased sensitivity to bright lights or glare, which can lead to discomfort in well-lit environments.

6. Visual Distortions: Some individuals may experience halos or glare around lights, particularly at night, which can be exacerbated by fatigue.


Causes of Eye Fatigue
Several factors can contribute to eye fatigue, including:
1. Prolonged Screen Time: Extended use of computers, tablets, or smartphones can lead to digital eye strain, as these devices often require intense focus and reduce the frequency of blinking.

2. Improper Prescription: Wearing glasses or contact lenses with an incorrect prescription can cause the eyes to work harder, leading to fatigue.

3. Poor Lighting Conditions: Insufficient or harsh lighting can strain the eyes, particularly during reading or detailed work.

4. Psychological Factors: Stress and anxiety can exacerbate the perception of eye fatigue, making it feel more pronounced.

5. Dry Eye Syndrome: Insufficient tear production can lead to discomfort and fatigue, as the eyes struggle to maintain moisture and clarity.


Solutions for Eye Fatigue
To alleviate eye fatigue, consider the following strategies:
1. Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps relax the eye muscles and reduce strain.

2. Adjust Your Workspace: Ensure that your computer screen is at eye level and about 20-30 inches away. Use proper lighting to minimize glare and shadows.

3. Use Artificial Tears: If dry eyes are a concern, consider using lubricating eye drops to keep the eyes moist.

4. Regular Eye Exams: Ensure that your prescription is up to date and discuss any symptoms with your eye care professional. They can check for underlying conditions that may contribute to fatigue, such as refractive errors or dry eye syndrome.

5. Limit Screen Time: Try to reduce the amount of time spent on screens, especially before bedtime, to allow your eyes to rest.

6. Practice Relaxation Techniques: Stress management techniques, such as mindfulness or deep breathing exercises, can help reduce the psychological aspects of eye fatigue.


Regarding Your Concerns
You mentioned experiencing halos around lights and having undergone a retinal examination that showed no significant issues. The term "break hole" you referenced could be related to a condition known as a "retinal break," which is often associated with retinal tears or detachments. However, if your doctor indicated that your retina is healthy, it is likely that your symptoms are more related to eye fatigue or dry eye rather than a serious retinal condition.

If you are experiencing persistent symptoms or if your visual disturbances worsen, it is crucial to follow up with your eye care provider. They can provide a comprehensive evaluation and determine if further investigation is necessary, especially if you have concerns about conditions like floaters or retinal issues.

In conclusion, while eye fatigue can be uncomfortable and concerning, understanding its symptoms and causes can empower you to take proactive steps toward relief. Regular check-ups and open communication with your eye care professional are key to maintaining eye health and addressing any issues that arise.
