The Little Known Coronavirus Symptom Affecting People’s Eyes

Covid cases are on the rise again in the UK, with the number rising 43 percent last week.

It is the highest number of infections since early May and is believed to be the result of new Omicron variants – BA.4 and BA.5.

With the number of cases on the rise, experts are warning patients about some of the symptoms to watch out for, including blurred vision.

Professor Tim Spector, of the ZOE Symptom Study App, estimates that about 50 percent of ‘new colds’ are in fact Covid, and experts suggest there are two distinct symptoms of the latest variants: fatigue and dizziness, which can accompany headache, blurred vision and loss of appetite.

According to data released last year, more than 10 percent of people who contract Covid develop eye or ear symptoms, which can last for some time.

Meanwhile, separate studies indicate that during the first 18 months of the pandemic, about 11 percent of patients experienced eye problems.

The most common is considered conjunctivitis, with 89 percent of people experiencing eye symptoms being affected by the condition, according to researchers in Iran.

Other symptoms include dry eyes, redness, itching, blurred vision and sensitivity to light. Bhupendra Patel, of the John A. Moran Eye Center at the University of Utah, believes that about a third of those with Covid have some form of eye problem.

Hearing and balance problems can also be signs of Covid. In a 2021 study, Zahra Jafari, an audiologist and cognitive neuroscience specialist at the University of Lethbridge in Alberta, reported dizziness or lightheadedness in 12 percent of patients. Tinnitus and hearing loss were also recorded.

Last week an estimated 1,415,600 people in the UK had Covid, with the ZOE app reporting that the most common symptoms among fully vaccinated people are a runny nose, headache, sneezing, sore throat and a persistent cough.

The earlier ‘traditional’ symptoms, such as those still listed on the government’s website, such as anosmia (loss of smell), shortness of breath and fever, are way down the list, 6, 29 and 8, respectively. cough is now number 1.5 if you have had two doses of vaccine, so is no longer the main indicator of having COVID,” explain ZOE scientists.

“Oddly, we found that people who were vaccinated and then tested positive for COVID-19 were more likely to report sneezing as a symptom compared to people without a shot.”
