Eye Flashes: Causes, Concerns, and Solutions - Ophthalmology

More Info

---

Understanding eye flashes can be quite complex, especially when they are accompanied by other symptoms such as discomfort and visual disturbances. Based on your description, it seems you are experiencing a combination of eye flashes, discomfort, and a history of retinal issues. Let's break down your concerns and provide some insights.


Causes of Eye Flashes
1. Retinal Issues: Given your history of a retinal tear that was treated with laser surgery, it's important to monitor any new symptoms closely. Eye flashes can occur when the vitreous gel inside the eye pulls on the retina, which can happen after surgery or due to changes in the vitreous as we age. This pulling can create the sensation of flashes or floaters.

2. Vitreous Detachment: As we age, the vitreous gel can shrink and pull away from the retina, leading to flashes of light. This is often benign but can sometimes lead to more serious conditions like retinal tears or detachment.

3. Increased Eye Pressure: You mentioned that your eye pressure is at 20 mmHg, which is on the higher side of normal. Elevated intraocular pressure can lead to discomfort and may be a risk factor for glaucoma, which can also cause visual disturbances.

4. Eye Strain: Prolonged use of glasses, especially if they are not the correct prescription, can lead to eye strain. This can cause discomfort and may exacerbate the sensation of flashes.


Addressing Your Concerns
1. Will Wearing Glasses Increase My Prescription?: Wearing glasses does not inherently increase your prescription. However, if your vision changes due to underlying conditions or if your glasses are not the correct prescription, you may find that your vision deteriorates. Regular eye exams are crucial to ensure your prescription is up to date.

2. Does Lutein Help the Retina?: Lutein is a carotenoid that is believed to have protective effects on the retina. It may help filter harmful blue light and reduce oxidative stress, potentially benefiting overall eye health. However, while it can be a part of a healthy diet for eye health, it should not be seen as a cure for existing retinal issues.

3. Can I Wear Contact Lenses?: Whether you can wear contact lenses depends on the health of your eyes. Given your history of retinal issues and current symptoms, it is essential to consult with your eye care professional. They can assess your eye health and determine if contact lenses are safe for you. If you experience discomfort or increased pressure while wearing glasses, it may be worthwhile to explore different types of lenses or contact lenses that may provide more comfort.


Recommendations for Management
- Regular Eye Exams: Continue to have regular check-ups with your eye doctor, especially given your history of retinal issues. This will help monitor any changes in your eye health.

- Manage Eye Strain: Take regular breaks from screens and ensure your workspace is well-lit to reduce strain. The 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) can be helpful.

- Stay Hydrated and Maintain a Healthy Diet: Proper hydration and a diet rich in antioxidants (including lutein) can support overall eye health.

- Discuss Symptoms with Your Doctor: If your flashes increase in frequency or intensity, or if you experience any new symptoms like a curtain or shadow over your vision, seek immediate medical attention.

In summary, while eye flashes can be concerning, understanding their potential causes and maintaining regular communication with your eye care provider can help manage your symptoms effectively. Always prioritize your eye health and do not hesitate to seek professional advice when needed.
