When it comes to understanding eye floaters and their potential implications for retinal health, it's essential to differentiate between benign floaters and more serious conditions that could affect your vision. Based on your description, it seems you have been experiencing some unusual visual phenomena, particularly after your recent eye examination.

Firstly, floaters are typically small specks or strands that drift through your field of vision. They are usually caused by changes in the vitreous gel that fills the eye, which can become more liquid as we age, leading to the formation of these floaters. In most cases, floaters are harmless and a common occurrence, especially in individuals with myopia (nearsightedness), as you mentioned you have significant myopia.

However, the sudden appearance of a "bubble-like" spot that disappears quickly, especially if it occurs consistently in the same location, could warrant further investigation. While this phenomenon may still be classified as a type of floater, it is crucial to consider other factors, particularly regarding the health of your retina and macula (the central part of the retina responsible for sharp vision).

During a dilated eye exam, which includes the use of a mydriatic agent to widen the pupil, an eye care professional typically examines the retina and the macula. This examination should include checking for any signs of retinal tears, detachments, or other abnormalities. If your retina was deemed normal during your last visit, that is reassuring; however, if you are experiencing new symptoms, it is essential to communicate these to your eye doctor.

The fact that you are noticing this bubble-like spot particularly after wearing glasses or after prolonged periods of eye closure could suggest a few possibilities. It might be related to the way light is refracted through your lenses or even a transient visual phenomenon related to changes in your eye's focus. However, it could also indicate a more complex interaction between the vitreous and the retina, especially if you have a history of high myopia, which increases the risk of retinal issues.

If you are concerned about the possibility of a retinal problem, such as a tear or a condition affecting the macula, it is advisable to seek a follow-up appointment with your eye care provider. They may perform additional tests, such as optical coherence tomography (OCT), which provides detailed images of the retina and can help identify any underlying issues that may not be visible during a standard examination.

In summary, while floaters are often benign, any new or changing visual symptoms should be taken seriously. It's essential to maintain open communication with your eye care provider and report any changes in your vision promptly. Early detection and intervention are key in preventing potential complications related to retinal health. If you have any lingering concerns or if your symptoms worsen, do not hesitate to seek immediate medical attention. Your vision is invaluable, and staying proactive about your eye health is crucial.
