Can Floaters Cause Blurry Vision? Your Eye Symptoms - Ophthalmology

More Info

Floaters, or "muscae volitantes," are common visual disturbances that many people experience, particularly as they age. They appear as small, shadowy shapes or spots that drift across your field of vision. While floaters themselves are generally harmless, they can sometimes be associated with other eye conditions, particularly if they are accompanied by flashes of light or a sudden increase in their number.

In your case, you mentioned that you have been experiencing floaters in both eyes for the past six months, along with occasional flashes of light. You have also noted that your left eye has recently become more blurry when looking at objects. It's important to understand the relationship between floaters and blurry vision.

Floaters are caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the formation of floaters. This process is usually benign, but in some cases, it can lead to more serious conditions such as retinal tears or detachment.

Blurry vision, on the other hand, can have various causes. In your situation, since you have a history of myopia (nearsightedness) with a prescription of -3.50 diopters, it is possible that the blurriness in your left eye could be related to your refractive error. If your glasses or contact lenses are not providing adequate correction, this could lead to blurred vision. Additionally, if there are changes in the vitreous or the retina, these could also contribute to visual disturbances.

Given that you have already undergone eye examinations at two different clinics, and both reported no abnormalities in your retina, it is reassuring. However, the fact that you are experiencing increased blurriness in one eye warrants further investigation. Here are some considerations:
1. Regular Eye Exams: Continue to have regular eye exams, especially since you have a history of floaters and myopia. If you notice any sudden changes in your vision, such as an increase in floaters, flashes of light, or a shadow in your peripheral vision, seek immediate medical attention.

2. Monitor Symptoms: Keep track of your symptoms. If the blurriness persists or worsens, or if you experience any new symptoms, it is essential to return to your eye care provider for a thorough examination.

3. Consider Other Factors: Factors such as eye strain, fatigue, or dry eyes can also contribute to blurry vision. Ensure you are taking breaks during prolonged screen time and consider using artificial tears if you experience dryness.

4. Consult a Specialist: If your symptoms continue to be concerning, consider consulting a retinal specialist. They can perform more detailed imaging tests, such as optical coherence tomography (OCT), to evaluate the health of your retina and vitreous.

In summary, while floaters are typically benign, the recent blurriness in your left eye should be monitored closely. It is crucial to maintain open communication with your eye care provider and report any changes in your symptoms. Regular check-ups and being proactive about your eye health will help ensure that any potential issues are addressed promptly.
