Introduction

Yellowing and cloudiness of the eyes may result from physiological causes, but could also be related to pathological conditions such as pinguecula or cataracts. Prompt medical treatment is recommended upon onset, with medication or surgical intervention chosen according to medical advice. Additionally, iridocyclitis could be a possible cause; patients are advised to seek timely ophthalmological evaluation and diagnosis at a hospital, followed by appropriate treatment based on the underlying cause.

Under normal circumstances, yellowish and cloudy eyes may be caused by physiological factors, but they could also be related to pathological conditions such as pinguecula or cataracts. Prompt medical treatment should be sought once symptoms appear, with treatment options—medication or surgery—chosen according to medical advice. The details are as follows:

I. Physiological Causes

Prolonged use of mobile phones, computers, or inadequate indoor lighting can impair ocular blood circulation, leading to a greasy, cloudy appearance of the eyeball. Mild cases usually do not require special treatment but call for maintaining good eye habits; severe cases should seek timely medical attention.

II. Pathological Causes

1. Pinguecula

Long-term exposure of the eyes to ultraviolet light can lead to nodules forming on the bulbar conjunctiva at the junction of the limbus in the palpebral area, resulting in gray-yellow nodules accompanied by cloudiness, dryness, redness, and swelling. After diagnosis, doctors may recommend argon laser photocoagulation to alleviate these discomforts.

2. Cataracts

Metabolic disturbances in the lens cause it to become cloudy, making the eye appear generally hazy and dull, often accompanied by blurred vision. In such cases, treatments like phacoemulsification cataract extraction or intracapsular cataract extraction may be performed under medical guidance, followed by proper postoperative eye care.

In addition, uveitis (iritis-cyclitis) could also be a possible cause. Patients are advised to visit an ophthalmologist at the hospital as early as possible for accurate diagnosis and targeted treatment based on the underlying cause.

Can people with pinguecula receive vaccines?

Whether patients with pinguecula can receive vaccines depends on their ocular condition and the type of vaccine. Vaccination can proceed normally if the pinguecula is not inflamed and the vaccine does not have ocular contraindications. However, if the pinguecula is in an acute inflammatory phase, vaccination should be postponed. Patients should monitor their eye condition before and after vaccination, avoid rubbing their eyes, maintain good ocular hygiene, and minimize exposure to irritants such as dust and ultraviolet light.

Can objects touched by COVID-19 patients transmit the virus?

The novel coronavirus can spread by contaminating surfaces through respiratory droplets from infected individuals. Others may become infected if they touch these contaminated surfaces and then touch their mouth, nose, or eyes. The virus survives longer in moist, enclosed environments, increasing transmission risk. However, the virus has a limited survival time on dry surfaces and is sensitive to alcohol-based and chlorine-containing disinfectants. Wearing gloves and frequent handwashing can effectively reduce the risk of infection.
