🕶 Polarized lenses for glasses: what they are and who needs them

Polarized lenses are a special type of sunglasses that not only block harmful ultraviolet radiation, but also eliminate dazzling glareThe light is reflected from horizontal surfaces such as water, snow, wet asphalt, metal, or glass.

🔬 How does polarization work?

When sunlight is reflected from a surface, it is partially polarizes - that is, it starts to oscillate mainly in one direction, creating intense horizontal glare. The polarized lens has a special vertical filter that prevents the passage of this reflected lightreducing glare and improving image contrast.

✅ Advantages of polarized lenses:

  1. Less eye fatigue
    The absence of glare means that your eyes do not strain, your vision does not "float," and you do not get a headache after prolonged exposure to the sun.
  2. A clearer image
    The "milky veil" from the reflected light disappears, the picture becomes deeper, the colors become more saturated.
  3. Improved safety while driving
    Polarized glasses allow you to see the road surface, pits, and markings better, even in bright sunlight or after rain.
  4. Ideal for water and mountains
    They are indispensable for fishermen, yachtsmen, skiers, and tourists - they reduce dazzle from water or snow surfaces.
  5. 100% protection against UVA and UVB
    As with all quality sunglasses, polarized models should have UV400 or the "100% UV protection" label.

⚠️ What you should know about polarized lenses:

  • Polarization does not replace UV protection, а complements it.
  • Not all sunglasses are polarized Always check the labeling or consult an optician.
  • By filtering out glare, polarized lenses can make it difficult to screen reading з liquid crystal displays (for example, in navigation devices or smartphones).

Some models of polarized glasses may have mirror finish or additional photochromic properties (chameleon effect).

👁‍🗨 Who are polarized lenses recommended for?

👓 How to distinguish polarized glasses?

  1. Lenses or packaging must be marked with "Polarized".

  2. Specialized opticians can perform test via LCD screen - turn the glasses at an angle, the display should go dark or the image should disappear.

Trust only to authorized sellers, such as "Optics of Defense"where you are guaranteed quality and true polarization.
