Visual Disturbances: Waves and Curves in Vision - Ophthalmology

More Info

---

Understanding visual disturbances such as waves and curves in vision can be quite concerning, especially when they manifest suddenly and intermittently. Based on your description, it seems you are experiencing visual phenomena that could be related to a few different conditions, but the most likely explanation is related to migraine aura, particularly if these disturbances are transient and resolve within a short period.


Possible Causes of Your Symptoms
1. Migraine Aura: The symptoms you describe, such as the appearance of wavy or curved lines in your vision, are often associated with a type of migraine known as "migraine with aura." This can occur even in the absence of a headache. The visual disturbances can include zigzag patterns, shimmering lights, or even temporary blind spots. These symptoms typically last from a few minutes to about half an hour and then resolve completely. Given that your symptoms have occurred on multiple occasions and have resolved after a short duration, this could be a plausible explanation.

2. Visual Disturbances from Eye Strain: Given your long hours of computer work and the use of contact lenses, eye strain could also contribute to visual disturbances. Prolonged screen time can lead to digital eye strain, which may cause symptoms like blurred vision, dry eyes, and even temporary visual distortions.
3. Retinal Issues: Although your eye examinations have returned normal results, it’s important to consider that some retinal conditions can cause transient visual disturbances. Conditions such as retinal detachment or vitreous detachment can lead to similar symptoms, but these are usually accompanied by other signs, such as flashes of light or a significant increase in floaters.

4. Optical Issues: The fact that you have high degrees of myopia (nearsightedness) and astigmatism could also play a role. Changes in the shape of the eye can lead to visual distortions, especially if your prescription is not up to date. It’s essential to have regular eye exams to ensure your prescription is accurate.


Recommendations for Management
1. Consult a Specialist: Since your symptoms are recurrent, it would be prudent to consult a neurologist or a specialist in headaches. They can provide a more comprehensive evaluation and determine if you are experiencing migraine auras or if there is another underlying issue.

2. Regular Eye Exams: Continue to have regular eye examinations to monitor your vision and ensure that your prescription is appropriate. If you notice any changes in your vision, such as an increase in the frequency or severity of these disturbances, seek immediate medical attention.

3. Manage Screen Time: To alleviate eye strain, consider implementing the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This can help reduce fatigue and discomfort associated with prolonged screen use.

4. Consider Visual Aids: If your current prescription is not providing clear vision, discuss with your eye care provider the possibility of updating your glasses or contact lenses. Proper correction can help reduce visual distortions.

5. Lifestyle Modifications: Ensure you are maintaining a healthy lifestyle, including adequate hydration, proper nutrition, and sufficient sleep, as these factors can influence overall eye health and reduce the frequency of migraines.


Conclusion
While your symptoms can be alarming, they are often manageable with the right approach. Keeping a detailed log of your symptoms, including their frequency, duration, and any associated factors (like stress or screen time), can be beneficial for your healthcare provider in diagnosing and managing your condition effectively. If your symptoms persist or worsen, do not hesitate to seek further evaluation.
