Circles in front of the eyes are usually caused by conjunctivitis that leads to secretions in the patient’s eyes, cataracts, and posterior vitreous detachment, etc. The exact cause needs to be determined by a face-to-face ophthalmologic examination in a hospital.
When the patient suffers from conjunctivitis, there will be secretions in the conjunctival sac, which may move to the surface of the cornea along with the tear circulation, thus leading to circles in front of the eyes when the patient looks at something.
When a cataract occurs with clouding of the lens, there may also be a ring in front of the eyes, which usually requires surgical treatment.
Posterior vitreous detachment, and the optic disk connected to the part of the vitreous is more dense, detached from the formation of a circle-shaped turbidity, the patient will also feel the field of vision in the circle floating.
If there is a circle in front of the eye, it is recommended to consult a doctor for a clear examination of the cause and follow the doctor’s instructions for targeted treatment, so as to avoid delaying the condition.
