Protect your eyes from the sun

Sunglasses by the pool. Remember to wear sunglasses to protect your eyes from the sun

Remember to always protect your eyes from the sun.

Although it is essential for the production of vitamin D, exposure to the sun, if excessive, can be dangerous for the skin and the eyes. We know the harmful effects of the sun on the skin (sunburn, even cancer …), but do you know that your eyes are also very sensitive to sunlight?

Therefore you you should adopt good sun protection habits such as wearing high quality sunglasses and learn about the UV index.

The sun is not your eyes’ friend

Ultraviolet (UV), infrared and blue light from the sun can cause serious eye damage. Radiation does not go hand in hand with the sensation of heat: it can indeed be strong even in cooler cloudy weather. To know the intensity of this radiation, you can refer to the weather report which indicates the UV index.

There are three types of UV rays:

UVA are the weakest ones. They cause aging of the skin. The cornea and lens block some of these rays, but protection is still needed, especially in children and people at risk.
UVB are responsible for tanning, sunburn, but also skin cancer. However, since hey promote the synthesis of vitamin D, short and careful exposures are beneficial. The eye is very sensitive to these rays.
UVC are very dangerous. The ozone layer acts as a natural barrier and block them

The sun can cause ocular pathologies

Prolonged exposure to the sun can cause significant visual disturbances and several pathologies.

Protect your eyes from the sun and preserve this capital. It is essential to help fight premature aging and promote good long-term vision.

Who is the more at risk

Some people are more sensitive to the effects of the sun than others. For example, never expose babies to the sun, and protect children thoroughly. The lens of the child’s eye transmits about 70% more UV than the adult eye, putting their retina at a larger risk. People with fair skin and blue eyes are also more sensitive.

One solution: protect your eyes from the sun!

Our eyes are smart: retina, cornea and lens partially protect us from the harmful rays of the sun. Nevertheless, it is not enough.

  • Wear a wide-brimmed hat or visor to block the sun
  • Take precautions during the time when the sun’s rays are strongest, 10 a.m. to 4 p.m. To check the sun’s intensity, take the shadow test: If your shadow is shorter than you, the sun’s rays are the day’s strongest.
  • The sun is ten times stronger near bright surfaces. Be extra careful on the beach and in the mountains because of sun reverberation on water and snow. In fact, the snow reflects 80% of the sun’s rays!
  • Some contact lenses have UVA and UVB protection and are a good complement to our natural defense. They will not, however, prevent glare.
  • Sunglasses. The best way to protect your eyes from the sun is to wear a pair of sunglasses as often as possible, even on a cloudy day. Make sure they absorb both UVA and UVB rays.

Tips to choose the right glasses:

  • A UV400 filter indicates that the UVA and UVB filters are 99 to 100%
  • Coverage: depending on the activity you favor, you may consider wraparound sunglasses to prevent harmful UV rays from entering around the frame. For example, if you go on the snow, prefer good quality ski goggles such as Giro or Oakley.
  • The hue intensity index: ranging from 0 to 4, 0 being the weakest. Keep in mind that class 4 prohibits driving a car.

Watch out for cheap glasses! Tinted lenses do not necessarily guarantee protection. Indeed, they reduce the intensity of light, allowing the pupil to dilate while they do not block the sun’s harmful rays. Therefore cheap sunglasses often have the opposite effect of what you expect.

The most important reasons to wear sunglasses are to shield your eyes from damaging sun rays, to enable you to see clearly and comfortably in conditions ranging from bright sunlight to overcast haze, and to protect your eyes from injury or irritation. So choose well!

Examples of popular sunglasses with good quality lenses are the Ray Ban Wayfarer. They also exist with polarized lens. You can wear polarized sunglasses for additional glare protection. Polarized lenses contain a special anti-glare filter that is able to block intense reflected light,  especially on the water or snow .

Take a good dietary supplement to help prevent sun damage and protect against blue light
