After developing floaters, it is essential to first visit a hospital for an examination to determine the underlying cause. If there's a serious issue, such as retinal or ciliary body pathological changes, it must be addressed promptly.

Some cases of floaters are due to the degeneration of the eyes, which occurs with aging, leading to problems with the vitreous. In such cases, treatments like acupuncture and moxibustion can be beneficial.

Moxibustion usually targets acupoints around the eyes. Be careful not to burn the skin. Useful acupoints include the temples, which are located on the outer side of the eyes, and others like Cuanzhu point and Sibai point. More distal points, such as Fengchi at the back of the head, and Hegu on the hand, also benefit the eyes.

There's also a beneficial acupoint on the outer side of the lower leg, five cun above the lateral malleolus, called the Guangming point, which is very beneficial for the eyes and can be treated with moxibustion. Additionally, frequent moxibustion at the Jiaji point, located about 0.5 cun (approximately 0.5 to nearly 1 cm) next to the midline of the cervical spine, can also benefit those with floaters.
