The eyes are the mirror of the soul. But a mirror that takes the brunt of the aggressions of our direct environment and our small personal excesses. Sun, screens, sugar or poor lifestyle contribute to the appearance of certain degenerations of the eye. The consequences: early or worsened myopia, and in some cases partial or total loss of vision. No need to wait for the next New Year's Eve to set good resolutions and maintain good eyesight longer.

The top 10 worst for the eyes

Difficult to give an ascending order of harmfulness on everything that can damage your eyes. But we have selected all the worst (bad) habits that can cause you eye damage in the long term, as well as immediate discomfort on a daily basis (and which are not so complicated to change).

1. Not protecting your eyes while tinkering

Doing DIY, drilling, sanding, or other heavy-duty stuff that kicks up loose dust and debris? So adopt protective glasses that will minimize the risk to your eyes.

It seems obvious but it gets better by saying it.

2. Tobacco!

We know that tobacco is bad for everything. And the eyes are no exception.

In addition to the smoke that stings on the surface, tobacco directly attacks the ocular tissue (as well as the rest of the body for that matter). Here too the risks of AMD are very real.

👉 Main consequence : a central vision that becomes more and more blurred over the years.

3. Alcohol

The occasional consumption of alcohol in small quantities is not a big concern, but the problems begin as soon as one consumes alcohol regularly and in large quantities.

Alcohol can affect the eyes in different ways, with some symptoms being more severe than others. Here are some of the problems that can arise from regular heavy drinking:

  • Blurred vision
  • Red eyes
  • dry eyes
  • Mood swings/difficulty focusing
  • Loss of vision or distorted vision
  • Involuntary movements

Does it make you feel like it? We don't either, I'm going to get myself a small glass of water.

4. Not protecting yourself from the sun

    The sun is a blessing. It constitutes our main contribution in vitamin D. Without this contribution, hello tiredness, muscular pains, lack of tone and sometimes even depressive state.

    We all feel that too. The low spirits of winter and its greyness, the vitality of the first beautiful days of spring.

    But for retinas, it's a different story. UV rays are extremely aggressive for them. It is therefore necessary to protect them with sunglasses (and not just any!).

    Note that these UV rays increase even more with the reverberation on the snow or the sea.

    On the other hand, the clouds stop them only a little: in gray weather it is still 90% of the UV rays that reach us.

    The result is a risk of cataracts, photokeratitis, ophthalmia or even melanoma . Syndromes that appear in your fifties when you've been playing around with eye protection all your life.

    So, from an early age, it's sunglasses. And then we keep them!

    5. Poor diet

    friends who eat anything

    More generally, a poor diet is clearly damaging to the eyes. It is above all the lack of daily vitamins that plays an essential role.

    So to remedy this, we think of its dose of fresh fruits and vegetables every day to fill up with vitamin C, E and zinc.

    We also favor vegetable oils and fish which are rich in omega 3.

    Focus on sugar

    Sugar is a kind of siren song for our brain: as delicious as it is harmful. Our bodies use glucose as their primary fuel source, so our brains evolved to like sweet foods .

    Biologically that means it generates dopamine to reward sugar and encourage you to eat it.

    ⚠️ It was useful in prehistory to motivate you to find this source of fuel but it is much less today when sugar is in abundance!

    Too much sugar inevitably leads to hypertension and diabetes , both of which are very bad for the eyes.

    • ⚡️ Hypertension prematurely wears out the optic nerve
    • 🫣 Diabetes promotes the appearance of cataracts, AMD (age-related macular degeneration) or glaucoma.

    Worse still, diabetic retinopathy can result in total and irreversible blindness.

    Sweets are good… but in moderation.

    So, we calm down on the sweets (yes, we know how difficult it is for us too!), and we pay attention to prepared meals that contain sugar where we least expect it (but why do we stick sugar in beef bourguignon or tabbouleh ???).

    6. Abusing screens without special attention

    We are not teaching you anything, screens, omnipresent in our current lives, are not terrible for the eyes. Between blue light and staring at a screen closely all day, our eyes take quite a beating.

    Circadian Rhythm Disruption

    Blue light, for example, is present in all types of artificial lighting, but also natural. The sun diffuses blue light, and it is very good like this:

    🌅 When getting up in the morning, it tells our body to no longer secrete melatonin and therefore to wake up.

    🌄 Ditto for the evening, stopping the sunlight is the signal to allow sleep. It was the natural cycle of things for a large part of humanity, but it has changed!

    The problem is that our evenings are illuminated with LED lamps and all our screens also emit blue light.

    🕹 Watching a movie, playing Counter Strike or scrolling like a maniac on Insta before going to bed does not send the right signals to our brain .

    Physical impact on the eyes

    Beyond disrupting the biological clock, too much blue light on a daily basis is bad for your eyes . You know it, you feel it, your eyes sting, dry up, and headaches appear.

    Especially since LED lights are the worst at sending the harmful spectrum of blue light deep into your retinas.

    🙅‍♂️ Visual fatigue then becomes a real scourge, whether to work, to have fun or even simply to find restful sleep.

    The consequences are not only immediate. Abusing screens without good protection causes the eyes to age prematurely and could accelerate cataracts, myopia which could have been avoidable or even the aggravation of hyperopia.

    7. Neglecting contact lenses

    Contact lenses are quite a good thing for anyone who wants to avoid prescription glasses. However, their direct contact with the eye can have harmful consequences if anything is done.

    Wearing time

    The lenses dry out the eyes, for this reason they should not be worn for more than 12 hours in a row (it's the max of the max, less time is better), and above all, do not sleep with them.

    It is even recommended to rest your eyes one or two days a week while wearing your glasses (but yes, they give you a too stylish look!).


    Another important point, cleaning: always use a real cleaning solution and especially not a simple saline solution. And of course, handle your contact lenses with clean hands.

    Finally, the lenses should never come into contact with water, in the shower or at the swimming pool, at the risk of developing an eye infection.

    8. Sleep with makeup on

    You come back from the evening and you are absolutely lazy to remove your make-up. However, you will have to stick to it. Besides being bad for the skin, not removing makeup before going to sleep is one of the best ways to irritate your eyes. The mascara which will inevitably interfere under the eyelids can cause conjunctivitis, styes or other bacterial infections which can have serious consequences.

    So force yourself a little, and console yourself by thinking about the job of removing make-up from the members of Kiss after a concert.

    9. Reading in low light

    Reading a book without good light requires a titanic effort from your eyes. You don't always realize it, because they are valiant and get used to it. But this fatigue, especially if repeated regularly, contributes to premature aging of the eyes.

    💡 So always try to read in a bright enough environment.

    If you read a book in your bed at night, remember that warm light bulbs (less than 3000K) are nice for the cozy atmosphere of a bedroom but are not really suitable for reading. While cold light bulbs (Over 4000K) are perfect for working but generate a lot of blue light, which is largely contraindicated before going to bed.

    To read without damaging your eyes, while keeping a soothing atmosphere, a 3000K light will do the job perfectly.

    A good book, happiness.

    10. Rub your eyes

    Whether it's fatigue or a simple nervous tic, know that when you rub your eyes you damage the blood vessels located under your eyelids.

    We are not here on an ultra serious gesture, but combined with other bad habits seen previously, and in the long run, it ends up having consequences.

    How to preserve your eyes as much as possible?

    There are things we can act on, such as quitting smoking (or at least reducing it), opting for a better diet (less sugary by the way), not looking directly at the sun (basic) or even providing a sufficiently lit environment. to your eyes when you read (or cook, or assemble the model of the Magister that you were given for your 14th birthday and which is still in its box, well, anything that requires some visual attention).

    And then there are the inevitable:

    • ☀️ The sun : hard to avoid it unless you adopt a lifestyle like Count Dracula.
    • 💻 Screens : how to do without it for work, without going to raise cows in Cantal? Not to mention that you should also give up on your flagship series, on gaming sessions... no, really, that's going too far.

    Inevitable but not impossible to thwart.

    Filter blue light

    By filtering the harmful spectrum of blue light emanating from our screens, we can protect ourselves from certain degenerations and early myopia.

    Not to mention day-to-day well-being: fewer headaches, better sleep, and the ability to level up God of War without feeling like your eyes are catching fire.

    ⚔️ The best weapon for that : anti blue light glasses or gaming glasses .

    Choose them accordingly:

    🟧 Plasma® Amber glasses (filtration of 86% of the harmful spectrum) for hardcore gamers
    ◻️ or Ghost® Clear lenses (filtration of 61% of the harmful spectrum) for daytime work.

    The icing on the cake, they have a sick style.

    “Yes, but I already wear glasses! ".

    No problemo, just opt ​​for overglasses that clip directly onto your frames (while waiting for our eyeglasses at the end of the year :))

    Let the Sunshine in!

    To live beautiful sunny days, without ruining your retinas, you need sunglasses worthy of the name.

    So out of the Gucci imitations bought in Ventimiglia or the Wayfarers from the beach market. They will do you more harm than good.

    Branded glasses most often offer good lenses, but do they reveal what they filter out from UV?

    For us, it is a priority. We therefore offer you a range reduced to its minimum, but terribly effective.

    With their Darkmatter® lenses that filter out 100% of UV rays and 96% of the harmful blue light spectrum, One Sun full coverage sunglasses and Urban Sun vintage sunglasses offer you the choice between two antagonistic styles for always the same level protection. Namely, the ultimate level.

    Thus, you are both protected from the sun, but also from the blue light of your Smartphone when you taunt your colleagues who are at work during your vacation.

    On the other hand, mom's advice remains valid, even with excellent glasses: “Never look at the sun, damn it! ".

    The final word: What damages the eyes the most?

    We can really preserve our retinas and the tissues of the eyeball with simple gestures. With a better lifestyle to begin with, but also by wearing what protects the eyes: glasses.

    Admit that the idea of ​​keeping good vision all your life is pretty cool, right?
