How to take care of your eyes and vision during a heatwave

In summer, and especially during heatwaves , our eyes are put to the test. Between intense UV rays , extreme heat and dry air , it is essential to adopt the right reflexes to protect your vision. Here are our Varionet tips for keeping your eyes healthy all summer long.

Protect your eyes from UV rays

Ultraviolet rays are most dangerous when the sun is high and the sky is clear. Prolonged exposure without eye protection increases the risk of eyestrain, irritation, dry eyes , premature aging of the eyes, and long-term cataracts.

• Choose CE-certified sunglasses with UV400 protection .
• Choose polarized lenses to reduce glare and improve visual comfort.
• Consider prescription sunglasses for comfort and safety.

Preventing dry eyes in summer

Dehydration also affects the eyes: it can cause stinging, a gritty feeling or blurred vision.

• Drink water regularly, even when you are not thirsty.
  
• Use artificial tears or simply saline solution if you feel uncomfortable.
  
• Avoid excessive air conditioning, which dries out the air.

Limit midday exposure

Between 11 a.m. and 4 p.m., UV rays and brightness are at their maximum, which increases visual fatigue.

• Go out preferably in the morning or late afternoon.
  
• Wear a wide-brimmed hat in addition to your sunglasses.
  
• Combine mechanical (shade) and optical (filtering lenses) protection.
• Don't forget sunscreen around your eyes.

Beware of reflections

In summer, sand, water or asphalt strongly reflect light, which intensifies UV exposure.

• Choose polarized lenses that eliminate annoying glare and maintain clear vision.

Protect your glasses from heat

High temperatures can deform frames, damage anti-reflective or photochromic coatings, and weaken polycarbonate.

• Do not leave your glasses on the dashboard or in direct sunlight.
  
• Store them in a hard case away from direct heat.

In summary

During a heatwave, your eyes are exposed to extreme conditions. By combining UV-blocking sunglasses , hydration , and simple actions , you can maintain your visual comfort and eye health all summer long.
