How Different Types of Light Can Affect Your Eyes

We’re surrounded by light every day—sunlight, phone screens, office lamps, car headlights. While most light is harmless in normal doses, certain wavelengths can cause eye strain or discomfort over time. Understanding how different types of light affect your eyes can help you choose eyewear that keeps them comfortable and protected.

Blue Light

Blue light is a high-energy, short-wavelength light found in both sunlight and digital screens. Long hours on computers, phones, or tablets may make your eyes feel tired or strained.

Zenni’s Blokz® lenses are designed to filter blue light and support visual comfort during screen time. You can add Blokz® to most Zenni frames, with or without a prescription, to help keep your eyes feeling fresh from morning emails to late-night streaming.

FL-41: For Light Sensitivity

Fluorescent bulbs—common in offices, classrooms, and hospitals—emit blue-green light that can flicker and trigger light sensitivity or headaches for some people.

Zenni’s FL-41 lenses feature a subtle rose-tint that filters wavelengths in this blue-green range, helping reduce sensitivity and improve comfort under harsh indoor lighting.

Infrared (IR) Light

Infrared, or IR, light is invisible but all around us—especially from the sun. While IR rays are a natural part of sunlight, prolonged exposure can contribute to eye discomfort.

EyeQLenz™ with Zenni ID Guard™ features a specialized coating that reflects select infrared wavelengths, adding an advanced layer of comfort and light defense. These photochromic lenses adapt to changing light, remaining clear indoors and tinting automatically in sunlight for seamless UV and IR defense.

Night Driving Lenses

Driving at night introduces unique visual challenges, from glare caused by oncoming headlights to reduced contrast in low light. As we age, these effects can become more noticeable.

Zenni’s Night Driving Lenses with NeoContrast™ technology help reduce glare and enhance contrast sensitivity, so you can drive with greater clarity and confidence after dark.
