Floaters, also known as vitreous opacities, can be divided into physiological and pathological types. Physiological vitreous opacities, even if severe, do not affect vision, but simply result in a higher number of floating objects seen in the field of vision. Pathological vitreous opacities, on the other hand, can significantly decrease vision and may even lead to blindness. Therefore, during an examination, it is important to first check the uncorrected visual acuity, corrected visual acuity, intraocular pressure, ocular B-ultrasound, and fundus photography. If there are any underlying eye conditions, they should be actively treated to potentially restore vision as soon as possible. It is also advisable to ensure adequate rest, reduce close-up activities, and maintain a light diet.
