Eye discomfort from strong sunlight glare

Outdoor sunlight can be extremely glaring.
Every time I step outside, my eyes hurt because of the harsh sunlight!
Why not choose a pair of lenses that truly suit your needs?

☀️ Sunlight Reaching the Earth

Sunlight that reaches the Earth includes ultraviolet rays B and C, visible light, and infrared rays. Among these, it is visible light that causes the dazzling glare people often experience.

However, UV rays become especially intense during summer and are a major factor in various eye diseases. Therefore, protecting your eyes from UV rays is essential.

🌈 Visible Light vs. Invisible UV Rays

Some customers tell us they want to “cut UV rays” to reduce glare. But in fact, that’s not entirely accurate.

Visible light, which has wavelengths from 380 to 780 nm, is the part of sunlight we can see — and it is this light that causes glare.
UV rays, though invisible, are harmful in other ways — such as causing sunburns, dark spots, and freckles — which makes people mistakenly associate UV with glare.

✨ What Causes Glare in Visible Light?

Among visible light, blue light (short wavelengths) is easily scattered and most responsible for glare.
For people sensitive to bright light, scattered blue light makes the surroundings appear overly bright, reducing visual clarity and comfort.
Prolonged exposure can also lead to eye fatigue.

🛡️ Countermeasures: UV + Blue Light + Glare

Outdoors, short-wavelength rays like UV and blue-violet light have high energy and may place additional stress on the eyes.
That’s why eye protection should address UV rays, blue light, and glare together.

Today, even some clear lenses are equipped with technology that blocks most UV rays, offering added protection for your eye health.

Measures / Innovations

To reduce glare outdoors, choose lenses that suit your lifestyle and environment.
Everyone experiences glare differently, so selecting the right lens tint and darkness level based on your personal sensitivity will deliver better results.
When wearing dark-tinted lenses, the pupils tend to dilate, allowing more UV rays to enter the eyes. That’s why it’s important to combine these lenses with a backside anti-reflective coating that blocks UV rays from reflecting into your eyes.
When purchasing sunglasses, always look for the label “UV400” to ensure proper UV protection.
