Can Covid-19 affect our eyes?

The Covid-19, all about the virus


The Coronavirus most often reveals itself through mild symptoms, such as a common cold, but it can also cause more serious problems, such as a difficulty in breathing, which can sometimes result in a hospitalization. It may also not generate any symptoms, but the risk of contamination is just as high. People with weaker immune systems, such as seniors, are most at risk.


Coronavirus, what about our eyes?


Covid-19 can actually cause eye problems. Note that the virus can be transmitted through the eye via droplets. The eyes are therefore a gateway for Covid-19 as for other viruses usually in circulation. So avoid rubbing your eyes or manipulating your eyelids unnecessarily.


In 1 to 3% of Covid-19 patients studied during the outbreak in China, moderate viral conjunctivitis has been reported. People who suffer from it present symptoms like rosy, watery and uncomfortable eyes. Conjunctivitis caused by Covid-19 can be treated within days. So the virus is not harmful to our eyes.


The inflammation can last 10 to 20 days after the onset of the first symptoms related to Covid-19. In more rare cases, the cornea is also affected: this is called keratoconjunctivitis.


Protecting yourself against the Covid-19 virus


Here are some great tips:


1 / Practice social distancing

2 / Wash your hands often

3 / Avoid touching your face

4 / Wear a mask

5 / If reusable lenses must be worn, use only the cleaning products recommended by your eye care professional.


Also note that if you wear glasses that do not fit your face, the chances that you touch your eyes are much higher. So, go to one of our branches to have your eyeglasses or sunglasses adjusted.

Color vision disorder, what is color blindness?

A color blind person does not see only in black and white, did you know? If the answer is no and you want to know more about this vision disorder, this article will help you … Definition, causes, treatments, let’s enter the world of color blindness.


What is color blindness?


Color blindness is a color vision disorder that is in fact hereditary. Indeed, there are several forms of color blindness including:


  • Those who have trouble distinguishing between red and green are the most popular form of color blindness.
  • Blue color blindness or monochromatism (where the person distinguishes only black, white and gray) are much rarer forms.
  • There is also semi-color blindness which is not as disturbing as color blindness.


Note that people of Asian or African descent are much less likely to suffer from color blindness. On the other hand, men are more likely to develop color blindness. The latter have only an X chromosome, and if the latter is damaged, color blindness can occur. As for women, they have two X chromosomes. Therefore, even if one of its chromosomes is damaged, the other can compensate for the functioning of the other. Also be aware that a woman who has a colorblind chromosome can actually pass it on to her child at birth.


Color blindness, what is the cause?


The retina of the eye has 3 cones that are sensitive to light. These cones are divided into 3 categories, including a cone that distinguishes red, another green and the last blue. If a cone does not work properly, this is where the problem arises, that is, the person will not perceive the color of the cone which does not work.


Color blindness is hereditary in most cases. However, in some cases, color blindness can be the result of an illness, such as that of the retina, an injury or a side effect due to taking medication.


Symptoms and complications


Color blindness can vary and be moderate to very strong. As a result, a color blind person will not realize his illness so quickly, unless his entourage notices. If you wear socks of different colors but you do not notice this difference, you can imagine, you should consult!


Be aware that a person with severe color blindness in green, for example, will not differentiate between red, brown, green, orange, and light red. If he has red color blindness, all the shades of red will appear very dull.


On the other hand, blue color blindness is either hereditary or is due to taking drugs which had a severe impact, thus damaging the retina or the optic nerve.



In conclusion, if the vision disorder is hereditary, there is unfortunately no treatment. However, if this disorder is the cause of an injury or illness, your doctor can effectively treat it. In all cases, it is best to consult a specialist. Do you want to know more about this wonderful organ that is the eye? You only have to consult our blog to know everything!

Eye health, the foods to focus on  

Eye health is very important because it is one of the most important organs of the human body. Drinking enough water, eating fruits and vegetables are habits that we know and practice every day. But what about the foods to favor to maintain the sight and preserve our eye health?

Focus on foods rich in lutein, zeaxanthin and vitamin C

Lutein and zeaxanthin are pigments that give food their color. It was revealed that the latter would have significant effects on sight. They slow the progression of certain ocular diseases such as age-related macular degeneration or cataract and also filter blue light. The benefits of vitamin C are well known, it slows the progression of cataracts, AMD and loss of visual acuity. So eat oranges and green vegetables like kale or spinach.

Vitamin A and beta-carotene

Foods rich in vitamin A and beta-carotene are orange vegetables such as sweet potatoes, carrots and spinach. These help the functioning of the retina, help the adaptation of the eye in darkness. Studies have also shown that foods rich in vitamin A and beta-carotene reduce the risk of contracting age-related visual diseases.

Zinc and Omega 3

Zinc is a key factor for the production of melanin, important for eye protection. On the other hand, if you suffer from omega 3 deficiency, you also risk suffering from visual diseases such as dry eye or AMD. Foods rich in zinc are red meat (beef, veal, game), chicken, oysters, wheat germ or sesame seeds.
Consuming these foods as often as possible promises good visual health. Moreover, if you want to have the opinion of a professional on the health of your eyes, go to one of our branches, in Rose Hill, Triolet, Beau Bassin and soon in Port Louis.

Baby’s eyes, how to take care of them ?

A baby is not blind at birth, he does not see well from a distance. It’s quite normal because the sight is the last sense that develops in an infant. The latter will not notice the bright lights until his seventh month. Taking care of his eyes can not be taken lightly.

Carefully clean the eyes of a baby

When cleaning the eyes of an infant, vigilance is required. Indeed, you must ensure that no impurity is directed to the eye. Be aware that babies produce a lot more phlegm than adults, which is why it is necessary to clean their eyes when they wake up.

How to clean the eyes of babies?

It is necessary to clean the baby’s eyes regularly, from the inside of the eyes, to the outside to move the impurities outward. Take a cotton swab, or a cotton disc soaked in saline. Lightly wipe the eye to remove any phlegm. This action is necessary to avoid any eye infections. But be careful, you have to use one compress per eye.

Protection and prevention

Do not worry, the eyes of infants are not as fragile as you think because the iris is very well protected by a membrane that allows the penetration of very little light. It is only towards the third or fourth month that this membrane begins to disappear and where it is necessary to be very careful. It is advisable not to expose them to too strong lights by using for example a cap, a visor or even sunglasses for baby.

Food, what should be consume ?

Milk is the main food of a baby, and is ideal for the child’s healthy development. When the child is ready for diversification, be sure to provide him with foods rich in:
Omega 3, especially DHA which is important for the visual function to capture light in the back of the eye. You will find omega 3 in sardines, fish or anchovies.
Carotenoids for good central and peripheral vision or to distinguish contrasts. You can find it in spinach, broccoli or kale.
Be vigilant and do not hesitate to consult if your infant is unable to fix his eyes towards his 2 months, or if he shows signs of strabismus. Visit one of our branches to benefit from the expertise and professionalism of our team.
