The sun arrives, visits to the beach, outdoor plans, and greater exposure of our eyes to the sun's rays. When we buy sunglasses, we pay special attention to the frame being to our liking, but what is truly important is knowing the characteristics of the lens. Understanding the difference between polarized and non-polarized glasses is essential.
What are polarized glasses?
Let's explain it in very clear terms. Of the light we receive from the sun, some rays are useful and others are not. Those that are not useful also harm us and are the ones reflected on asphalt, snow, metal, glass…
Polarized lenses have a filter that blocks these rays, allowing only the useful ones to pass through.
Advantages of polarized glasses over non-polarized ones:
- Sharper vision, with better contrast and NO GLARE.
- Total PROTECTION against Ultraviolet rays.
- Perfect for driving due to REDUCED EYE FATIGUE.
- Completely suitable for all ages, including children.
- Can be applied to any type of lens, prescription or not, with photochromic, mirror treatment…
- Ideal for athletes.
Due to the lens design, another difference between polarized and non-polarized glasses is that the orientation must be in a specific direction. When non-polarized lenses are mounted in the frame, if they are not progressive or bifocal prescriptions, the lens direction is not important. However, with polarized glasses, the lens orientation must be very precise and specific for the filter to work properly.
For summer, the difference between polarized and non-polarized glasses makes them more recommended by experts and opticians. Non-polarized glasses are recommended during the rest of the year or in areas where sun exposure is not intense.
