Eye Issues: Floaters and Nighttime Glare Explained - Ophthalmology

It's great that you're taking the time to understand your eye health, especially with concerns like floaters and nighttime glare. Let's break down your questions and provide some clarity.


Floaters and Flashing Lights
Floaters are small specks or strands that drift through your field of vision. They are usually harmless and are caused by changes in the vitreous gel that fills your eye. As we age, this gel can become more liquid and may clump together, casting shadows on the retina, which we perceive as floaters. If your eye doctor has confirmed that there are no retinal tears or serious issues, it's likely that what you're experiencing is a normal part of having floaters, especially if they are not accompanied by other symptoms like flashes of light or a sudden increase in floaters.

Flashing lights, often described as "seeing stars" or "lightning," can occur when the vitreous gel pulls on the retina. This sensation can be alarming, but if your eye exams have shown no signs of retinal detachment or other serious conditions, it may not be a cause for concern. However, if you notice an increase in the frequency or intensity of these flashes, or if they are accompanied by a sudden increase in floaters, you should contact your eye doctor immediately.


Nighttime Glare and Light Sensitivity
Regarding your experience with nighttime glare, especially with streetlights appearing overly bright or haloed, this is a common issue for many people, particularly those with refractive errors like myopia (nearsightedness) or astigmatism. The yellow streetlights you mentioned can create a halo effect due to the way light is scattered, especially if you have any degree of astigmatism. This scattering can make lights appear more intense or create a glare, which can be exacerbated by factors such as fatigue or dry eyes.

If your eye doctor has confirmed that your astigmatism has not worsened, it’s likely that your perception of glare is related to the lighting conditions and the type of bulbs used in streetlights. Traditional sodium vapor lights (the yellow ones) can create more glare than LED lights, which are often clearer and more focused.


Frequency of Eye Exams
As for how often you should see your eye doctor, it generally depends on your specific situation. If your eye exams have shown no significant changes and you are not experiencing new symptoms, it may not be necessary to return every month. Most eye care professionals recommend annual check-ups for those with stable vision and no significant eye health issues. However, if you experience new symptoms, such as a sudden increase in floaters, flashes of light, or significant changes in your vision, you should seek an evaluation sooner.


Conclusion
In summary, floaters and occasional flashes can be normal, especially if your eye doctor has ruled out serious conditions. Nighttime glare can be influenced by lighting conditions and your eye's refractive state. Regular eye exams are important, but the frequency can often be adjusted based on your specific needs and any changes in your symptoms. Always trust your instincts—if something feels off, don’t hesitate to reach out to your eye care provider. Your vision is important, and staying informed is key to maintaining eye health.
