Introduction
If eye redness and blurred vision are caused by eye strain, reduce eye use, avoid staying up late, or apply local warm compresses. If caused by conjunctivitis, follow medical advice to use medications such as chloramphenicol eye drops, erythromycin eye ointment, or rifampicin eye drops. If due to keratitis, treatment may include acyclovir eye drops, ganciclovir eye drops, entecavir eye drops, or surgical interventions such as eyelash inversion surgery or corneal transplantation.
Under normal circumstances, redness and blurred vision may be caused by physiological factors or pathological conditions such as conjunctivitis or keratitis. Appropriate management can be selected based on the specific cause. The details are as follows:
I. Physiological Factors
If excessive eye use over a prolonged period leads to eye strain and conjunctival congestion, normal vision may be affected, resulting in blurred vision and bloodshot eyes. This can be improved by reducing eye strain, avoiding staying up late, or applying warm compresses locally.
II. Pathological Factors
1. Conjunctivitis
In cases of conjunctivitis, inflammation causes local blood vessel dilation in the conjunctiva, and increased secretions may obstruct vision, leading to red, blurry eyes. Treatment may include medications such as chloramphenicol eye drops, erythromycin eye ointment, or rifampicin eye drops, used according to medical advice.
2. Keratitis
In keratitis, inflammatory stimulation causes blood vessel dilation and congestion in the eye, along with corneal damage, resulting in blurred vision and redness. Under a doctor's guidance, antiviral medications such as acyclovir eye drops, ganciclovir eye drops, or entecavir eye drops may be used to control infection. Surgical treatments such as eyelash surgery (for trichiasis) or corneal transplantation may also be recommended depending on the physician’s assessment.
In addition, glaucoma could also cause redness and blurred vision. Patients are advised to seek timely ophthalmologic evaluation to determine the underlying cause and receive appropriate treatment as directed by a physician.
