CEO, Designer and Blogger, Amy Roiland, knows a thing or two about fashion and how to pull off a chic, modern look that incorporates eyeglasses as an accent piece. Her blog, A Fashion Nerd, is one of our favorites here at Zenni, so we thought we would reach out to see if we could pick her brain a bit and maybe model some of our latest frames. Check out the interview below as well as some of her amazing images from the photo shoot!
Zenni: What is your best eyewear fashion moment?
Amy: Every moment is my best eyewear fashion moment, I wear eyeglasses every single day. The bigger and more crazy the glasses the better for me. I love big round fun eyeglasses.
Zenni: What does wearing glasses mean to you?
Amy: It means the world to me, its my entire character. A fashion nerd embodies me 100%. I am a nerd and I am a nerd for fashion. I wear eyeglasses every day.
Zenni: What trends do you see in eyewear for 2015?
Amy: Crazy fun colorful amazing shapes.
Zenni: What current fashion trends are you embracing?
Amy: I never really follow trends .. But I do love the long trench coats and jackets, that trend is very cute, very alexander wang. I love mixing feminine styles with masculine styles.

You’ve probably seen drugstore sunglasses labeled “polarized.” Maybe you looked at those next to sunglasses that weren’t polarized, and wondered what the difference was. Or maybe your eye dr. recommended getting polarized lenses, but you weren’t sure how they worked and what benefit they offered.
Well, we’re going to tell you! Very simply, here’s what polarized lenses do: they reduce glare by blocking horizontal light rays.
Why horizontal? Here’s a little background on how polarization works: light comes from the sun in all directions, and it is reflected in every direction, too. When it reflects from light-colored horizontal surfaces – such as a white sidewalk, a white-sand beach, snow, or sunlight reflecting on water – it is said to be polarized horizontally. Light that is polarized horizontally is responsible for most of the glare that interferes with our vision.
How do polarized lenses work? To understand this, it’s useful to think of window blinds. Let’s start with Venetian blinds, which are horizontal. When Venetian blinds are open, light comes into the room in horizontal stripes, depending on the angle of the sun and the angle the blinds are open.
Polarized lenses are more like vertical blinds. When vertical blinds are open at a certain angle, light comes into the room in vertical stripes. Since horizontally reflected light is responsible for most of the glare we see, the polarized tint is placed on the sunglass lens in vertically angled strips. These vertical strips of tint allow vertically reflected light into the eye but block horizontally reflected light – greatly reducing horizontally polarized glare.
Most polarized lenses are sunglasses. Polarized sunglasses are especially popular with boaters, since water is a very reflective surface on a sunny day. Polarized sunglasses are also great for other outdoor activities, such as golfing and tennis, since they can help to sharpen the focus on the ball. They can also be good for driving, since polarized lenses reduce the glare that reflects from the shiny hood of a car, or the glare from the surface of the road on a hot, sunny day.
However, in some situations there can be drawbacks to polarized lenses. They can be problematic for skiing, since blocking the reflected glare off an icy patch might prevent the skier from noticing and steering away from a potential hazard.
In addition, it can sometimes be difficult to read liquid crystal display (LCD) or light-emitting diode (LED) screens on a boat or plane’s instrument panel while wearing polarized sunglasses. This could interfere with the pilot’s ability to clearly read and quickly respond to the information on the instrument panel. This could also apply to the global positioning system (GPS) and other displays of a car’s dashboard, a smart-phone, an ATM, or a self-service gas pump.
An oddity you may notice while wearing polarized sunglasses is that when you look at your car’s rear or side window from the outside, or perhaps the windows on an office building, you may see splotchy, iridescent spots. When you remove your polarized sunglasses, these spots are invisible.
This effect is created because you are looking at heat-tempered glass. The heat-tempering creates several stress points on the glass, enabling the glass, when broken, to crumble into small, granular chunks, which are safer than splitting the glass into sharp, jagged shards. The stress points also reflect the light in different directions from the parts of the glass that don’t have these stress points. The stress points prevent the polarized lens from filtering out the light evenly across the surface of the glass, creating the splotchy, iridescent effect.
If you are unsure if your sunglasses are polarized, here’s a fun, simple test to see if they are. Hold your sunglasses up to a computer screen, which has an anti-glare coating similar to the anti-glare coating on a polarized lens. Angle your sunglasses about 60 degrees, with one side of the frame at 10 o’clock and the other at 4 o’clock. If the lenses are polarized, they will turn black.
You could also take the test with two pairs of polarized sunglasses – hold one pair at a horizontal (180-degree) angle. Now hold the other pair in front of the first pair, but rotate this second pair of sunglasses a half-turn, till it’s straight up and down, at a vertical (90-degree) angle. You will see that the lenses of both pairs of sunglasses turn considerably darker where the two lenses overlap when they are perpendicular. This is because when you angle one polarized lens to another perpendicularly, they block glare both horizontally (the horizontal pair) and vertically (the vertical pair).
At Zenni Optical, we offer polarized sunglasses in our 1.50 and 1.59 index single-vision and progressive (no-line bifocal) lenses, and in our 1.49 index bifocal lens. All of our detachable sun shades, whether magnetic or clip on, whether standard (the same tint color and shade all the way through) or gradient (the tint is darker at the top, getting progressively lighter toward the bottom) are polarized.
A note of caution regarding drugstore sunglasses that are not polarized. If the lens is a non-polarized, darkly tinted lens not treated to block UV rays, it could be more dangerous to the eye than wearing clear, un-tinted glasses that have 100-percent UV protection. This is because the dark tint could cause the pupil to dilate, allowing more harmful UV rays into the eye.
You can rest assured that on every pair of glasses Zenni Optical makes, tinted or clear, we include a 100-percent UV-protection coating – for free.
In addition to polarized sunglasses, Zenni Optical also offers a different kind of sunglass lens that sometimes people confuse with polarized: photochromic lenses, which turn dark in the bright sunlight and become clear again in the shade or indoors.
Although you may have heard about a new technology that adds polarization to photochromic lenses, Zenni Optical does not offer these lenses at this time. Our polarized lenses are permanently tinted sunglasses that greatly reduce glare.
