the Causes of Visual Flashes When Closing Eyes - Ophthalmology

More Info

Visual flashes, particularly when closing your eyes or in low-light conditions, can be concerning and may stem from various underlying causes. Based on your description, it seems that you are experiencing small bright spots or flashes of light, which can be quite distressing, especially when trying to sleep. Here, I will outline some potential causes and considerations regarding your symptoms.

1. Phosphenes: These are the sensations of light that occur without light actually entering the eye. They can be triggered by pressure on the eyes, such as when you rub them or close them tightly. Phosphenes can also happen spontaneously and are generally harmless.

2. Visual Migraines: Even if you do not have a history of migraines, visual disturbances can occur independently. These may present as flashes of light or zigzag patterns in your vision. They often resolve within a short period but can be alarming.

3. Retinal Issues: Conditions such as retinal detachment or tears can cause flashes of light. If you have a history of high myopia (nearsightedness) or other eye conditions, you may be at a higher risk for these issues. Symptoms typically include flashes of light, floaters, or a shadow in your peripheral vision. If you suspect this, it is crucial to seek immediate medical attention.

4. Vitreous Detachment: As we age, the vitreous gel inside the eye can shrink and pull away from the retina, leading to flashes of light. This is often benign but should be monitored, especially if accompanied by other symptoms.

5. Dry Eyes: Inadequate lubrication of the eyes can lead to visual disturbances, including flashes or spots. This is particularly common in individuals who spend long hours in front of screens, as you mentioned.

6. Stress and Fatigue: High levels of stress and fatigue can exacerbate visual disturbances. If you are experiencing anxiety or sleep disturbances, this may contribute to your symptoms.

7. Neurological Factors: In some cases, visual disturbances can be related to neurological issues. If you experience other symptoms like headaches, dizziness, or changes in coordination, it is essential to consult a healthcare professional.


Recommendations:
- Seek Medical Attention: Given the nature of your symptoms, especially if they are persistent or worsening, it is advisable to consult an eye care professional. They can perform a comprehensive eye examination, including a dilated fundus exam, to rule out any serious conditions.

- Manage Screen Time: If you are frequently using your phone or computer in low-light conditions, consider reducing screen time before bed. The blue light emitted from screens can strain your eyes and disrupt your sleep cycle.

- Eye Care: Ensure you are taking regular breaks from screens (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds). Additionally, consider using artificial tears if you experience dryness.

- Stress Management: Incorporate relaxation techniques such as deep breathing, meditation, or gentle yoga to help manage anxiety and improve your overall well-being.

- Sleep Hygiene: Establish a calming bedtime routine to help signal to your body that it is time to wind down. This may include dimming the lights, reading a book, or practicing relaxation exercises.

In summary, while visual flashes can be benign, they can also indicate underlying issues that require attention. It is essential to monitor your symptoms and seek professional guidance to ensure your eye health and overall well-being.
