Raising awareness by educating everyone (children, employees, athletes, handymen, etc.) is the way to protect the eyes by becoming aware of the various daily threats. These are diverse and varied: the danger of exposure to the sun, sports injuries, splashes at work, digital eye strain linked to exposure to blue light, etc.
By taking care of his eyes and your vision, you are also taking care of yourself and your general health. During a complete eye exam, the ophthalmologist can detect signs of certain diseases, even undeclared ones, such as diabetes, high blood pressure, tumours, multiple sclerosis, etc.

Good food for good eyesight!
We think of paying attention to what we eat to improve nail growth or to have shiny and healthy hair, but our eyes are often neglected!
Yet they also require that we take care of (y)them , starting with what we put on our plates.
A good diet makes it possible to avoid all sorts of inconveniences due to certain deficiencies , such as AMD (age-related degeneration), glaucoma or quite simply to avoid worsening an already existing sight problem .
To begin with, a balanced and varied diet helps maintain a healthy overall lifestyle.
Here is our pick of the best foods for healthy eyes:
These are polyunsaturated fatty acids that are necessary for the proper functioning of the human body but that it cannot produce by itself. They must therefore be found in the foods we eat. They are present in large quantities in nuts, chia seeds, flax seeds, in shrimp and in fatty fish such as herring, salmon, sardines, etc.
Vitamins A, B, C and E:
- Vitamin A is one of the molecules that make up the retina , it helps protect the cornea. It becomes very useful during conjunctivitis, glaucoma, cataracts or major vision problems , indeed a vitamin A deficiency would cause total blindness .
Vitamin A is found in calf's liver, carrots, broccoli, spinach...
- Vitamin B improves eyesight and prevents its decline , especially the "sub-vitamin" B2, riboflavin.
It is found in abundance in foods of animal origin such as cheese, eggs, meat or fish. It is also found in green vegetables such as spinach, asparagus or even in cereals or brewer's yeast.
- Vitamin C plays an important role in reducing the risk of cataracts and AMD . Indeed, the retina and the lens are bathed in a fluid with a very high vitamin C content . It is therefore necessary to ingest vitamin C to allow a good balance.
Vitamin C is easy to find in large quantities: in citrus fruits, red fruits such as blueberries or blackberries, broccoli, peppers...
- Vitamin E would have a protective effect against AMD and cataracts . It would reduce the progression of these disorders .
A daily dose of it by eating for example almonds, hazelnuts, sunflower seeds, avocados, etc. would provide protection against these diseases.
It is a very good element in the preservation of your sight and the good health of your eyes , it is found in cocoa, wheat germ, eggs, cashew nuts.
In order to have healthy eyes, integrating these foods into a balanced diet is the solution. When the good weather arrives, it is easy to find many fresh products rich in vitamins and minerals. It is also possible to take food supplements to complete a varied and balanced diet. But like everything, be careful with the doses taken, an overdose would cause negative side effects.
Foods to avoid:
A diet too rich in omega-6 including too many vegetable oils, seeds, eggs or certain meats would tend to cancel the effects of omega-3.
Processed foods of industrial origin which have little nutritional value and therefore no vitamins, minerals, necessary for the functioning of the body in general.
An unhealthy body will lead to vision problems as you age.

Sitting in front of the computer for 8-12 hours can have different impacts on your body. One of the first discomforts suffered is eye fatigue , followed by headaches and backaches . By performing simple yoga exercises regularly, you can effectively reduce those discomforts that come with prolonged computer use.
A study was conducted in a software development company in India, it was requested with the help of 300 participants. Half had to include yoga practice in their daily work routine, while the others were placed on a waiting list as a 'control' group. For two months, the “yoga” group practiced different yoga exercises for one hour a day for five days a week. On the other hand, the control group pursued other recreational activities during the same time allocated to the yoga group.
At the start of the study, each participant rated the genes and level of discomfort related to eyestrain .
At the end of the study, eye strain discomforts were found to be significantly reduced in the “yoga” group, while the control group reported no significant changes in their eye problem.
The yoga group noted improvements in the following symptoms:
- shooting eyes
- Blurred vision
- dry eyes
The researchers reported that the significant improvement in eye strain in the yoga group was caused by increased relaxation. When the human body is in a relaxed state, the eyes instinctively blink more often , reducing eye strain.
If you, too, are considering performing some simple yoga exercises to reduce eye strain, here's the program for the study:
- 10 minutes of regulated breathing
- 15 minutes of yoga posture
- 10 minute visual exercises
- 10 minute joint exercises
- 15 minute guided relaxation
You can choose to perform an abbreviated version of these yoga exercises during lunch breaks, before you start work, or whenever you feel the need.
Yoga exercises for the eyes:
Here are the specific eye exercises that have been shown to be very effective in reducing eye strain:
Sit down and start moving your eyes by moving your gaze in 8 different directions. Use your thumb to direct your gaze, following these instructions:
- Up down
- Counter-clockwise rotation
- Clockwise rotation
The flame :
For this exercise, you will need a candle. Place the lit candle at eye level. Start by staring at the flame, without blinking. After a minute, begin to de-focus and look at various points further away than the flame. Perform the exercise several times.
Sitting in your chair, rub your hands together to warm your palms. When they are hot, close your eyes and place both hands on them. This will block external light sources and allow the eyes to absorb heat from your hand. Take 10 deep, relaxing breaths and repeat the exercise if necessary.
To further enhance the positive effects of these exercises, wear blue light blocking glasses when you are in front of your screens!
