AS the old proverb goes, the eye’s are a window to the soul.
然而, your eyes also provide a window for detecting some of the earliest signs of some 健康 使适应.
Having red bloodshot eyes is fairly normal and usually just suggests you’re tired or have had too many heavy nights out on the town.
But if you’re also experiencing grittiness, burning or some watery yellow discharge coming from your eye, there might be something more serious going on.
“Red eye or conjunctivitis (eye infection) is very common and the reason for one in 10 consultations in GP surgeries,” Dr Nisa explained.
According to the GP, red eye can be caused by a variety of different health issues:
1. Inflammatory and infectious conditions:
“Red eye is often caused by inflammation and infectious conditions – sometimes bacterial.
“Viral red eye tends to cause a watery discharge, bacterial infection a yellow discharge,” 她说.
The GP also said that 冠状病毒, which is usually associated with infection of the lungs and heart, can also be the cause of an eye infection or red eye.
“Red eye can be a symptom and side effect of Covid-19.
“Covid-19 can enter the body via the eyes and travel to the brain from the back of the eye,” 她补充说.
Blepharitis is a common eye condition affecting the eye lid.
“It is caused by bacterial infection which causes the base of the eyelids to become inflamed.
“Blepharitis can also lead to red eye,” Dr Nisa said.
The condition is often caused by dirty or expired beauty products getting too close to the eye.
“Allergies like pollen, which causes hay fever, can cause red eye,” 她说.
“And also dust mites and sometimes animal hair cause allergic reactions can also cause red eye,” 她补充说.
5. Contact lenses
“Complications with contact lenses including not cleaning them before placing them in the eye which can cause abrasion to the surface of the eye allowing infection to enter,” the GP said.
AK is an infection of the cornea – the clear outer layer of the eye.
The condition happens when the parasite acanthamoeba gets trapped between the cornea and the contact lens.
It eats into the cornea, causing severe pain and in a quarter of cases, 失明.
