Blue Light is high-energy light found everywhere! We are exposed to it from the electronic devices we use daily. TVs, mobile phones, tablets and computer screens all emit Blue Light wavelengths that range from 380 to 500 nm.

Excess Blue Light can lead to a variety of problems. The American Optometric Association has shown that too much Blue Light may cause eyestrain. It can also increase the risk of macular degeneration. Equally important, overexposure to Blue Light can cause sleep cycle disruption by suppressing the production of melatonin.

Not all Blue Light is bad, and Fifth & Ninth's Blue Light glasses can help by blocking up to 32% of the harmful spectrum (400 to 455nm).

We offer Blue Light glasses for women, men, and children in a variety of frame styles and colors.  



Just as we're exposed to blue light daily, we are also exposed to ultraviolet radiation emitted from sunlight, also known as UV light. There are three parts to UV light: UVA, UVB, and UVC. UVA light wavelengths range from 320 to 400 nm, and UVB wavelengths range from 290 to 320 nm. UVC light is absorbed by the earth's surface and doesn't affect our skin or eyes.

The side effects of short-term exposure to UV light can lead to eye damage and puffy red eyes. Long-term exposure can lead to serious side effects such as cancer of the eyes and eyelids, damage to the cornea and retina, and cataracts. 

Fifth & Ninth's sunglasses feature 100% UVA and UVB protection and are available in a variety of trendy frame and color options for women and men.
