What Should I Do If I See Bug-like Shadows in My Vision?

The presence of insect-like shadows in the eyes is known as floaters. For floaters with mild symptoms, no special treatment is required, and oral administration of neurotrophic drugs such as cod liver oil and vitamin E capsules can be appropriate. Regularly drinking tea made from chrysanthemum, goji berries, and astragalus is also beneficial. However, if floaters are accompanied by retinal tears, they can lead to blindness, and thus standardized and active treatment is essential.

Floaters refer to the perception of small, floating shadows in the visual field, particularly noticeable when looking at a white background, often accompanied by a sensation of flashes. The main causes of floaters are the liquefaction and posterior detachment of the vitreous humor.

Prevention of Floaters

1. Dietary Prevention: Sufficient intake of vitamins is crucial for eye health. Vitamin A is an essential nutrient for the eyes. Vitamins C and E can neutralize free radicals, improve eye immune function, and prevent vision loss. B vitamins promote metabolism in eye cells and are beneficial for individuals with eye diseases. Foods rich in vitamins include animal livers, eggs, dried beans, meat, mushrooms, fresh vegetables, and fruits.

2. Prevention of Floaters for Long-Term Computer Use: Many white-collar workers spend several hours a day staring at computer screens, which can lead to various eye diseases due to excessive screen brightness. Additionally, overuse of the eyes, high stress levels, and inadequate rest can all contribute to the development of floaters. People who are overly sensitive or anxious may also be prone to this condition. It is recommended that individuals who work extended hours on computers take regular breaks to prevent eye strain.

3. Importance of Regular Eye Examinations: Approximately one-quarter of patients with floaters may have underlying ocular conditions that threaten vision, such as retinal tears, retinal detachment, vitreous hemorrhage, and uveitis. Ophthalmologists recommend regular eye examinations for individuals with high myopia, diabetes, or a history of hypertension. If there is a sudden increase in floaters, worsening vision, abnormal flashes of light, or a sensation of blocked vision, it is crucial to seek immediate ophthalmic evaluation for potential abnormalities.
