So How Do Polarized Lenses Actually Work
We see you, science and physics nerds! Heres the nitty gritty details of how polarized lenses actually work:
Polarized lenses block horizontal light rays, which not surprisingly, come from horizontal surfaces, like black pavement, clear water, or blinding snow. When sunlight strikes flat surfaces, it reflects off, matching the angle of that surface. Those horizontal light rays create glare that makes its way into your eyes. This glare can distract you, put you in danger, or even obscure the clarity of a beautiful view when youre out in the woods.
Polarized sunglasses to the rescue! Polarization means the lenses have been coated in a special chemical, then laminated in a vertical pattern. That chemical lamination blocks horizontal rays, only allowing in vertical rays. Its similar to those vertical window blinds you might see in a hotel room. The right kind of light gets in, without being overwhelming or distracting.
Benefits Of Polarized Sunglasses
The key advantages of polarized lenses are their ability to filter out harsh glare and reflections. When sunlight enters our atmosphere, it scatters until it collects, or becomes concentrated on flat surfaces. This newly concentrated sunlight is also referred to as polarized light.
Polarized light is emitted as bright, horizontal glare that can pose significant vision issues including cataracts, macular degeneration, or photokeratitis .
However, polarized sunglasses filter out the glare which in turn enhances your field of vision by creating sharper images and allowing the pure color of your surroundings to reach your eyes. Its these qualities that put them in a league of their own when compared to other sunglass lenses.

What Are The Disadvantages Of Polarized Sunglasses
So far, we’ve sung the praises of polarized sunglasses for driving, but what about the cons? Yes, there are some.
First and foremost, polarized lenses are notorious for effecting depth perception. By removing essentially a whole plane of horizontal light, your vision can appear “flatter.” While the severity of this illusion will depend on the individual, it is something to keep in mind if you are particularly sensitive to depth perception.
Another con of polarized lenses takes place in snowy condition. While polarization excels at cutting glare off snow, there is a drawback. Glare is one of the best ways to discern ice, and since polarized lenses block this glare, you will be more vulnerable to not spotting ice on the road. The takeaway note? Keep your driving conditions in mind especially for those who live in snowy environments.

An Overview Of Standard Sunglasses
Sunglasses help you see better in sunny conditions and can be particularly helpful in snow and near water. They protect your eyes against UV rays, which can harm your eyesight.
The American Academy of Ophthalmology recommends these guidelines to find the best pair of sunglasses:
- Focus on bigger models. These can protect your peripheral vision as well.
- Buy sunglasses that offer 100 percent protection against UV rays. Inexpensive models can protect your eyes as much as costlier options, as long as they protect your eyes against all harmful UV rays.
- Color can help if you have certain hobbies. Green, gray, or amber lenses can improve contrast, which helps if you enjoy sports. Amber lenses tend to block blue light.
- Darker lenses are best for everyday use. Lighter lenses may not provide enough protection.
Some regular sunglasses are a bit different from the traditional kind that have just one color. Variations include:
- Gradient sunglasses. These may be dark at the top but clear at the bottom. Some are dark at the top and bottom, and they may only be clear in the middle.
- Wrap-around glasses. These can fit over a pair of prescription glasses as long as they are big enough.
- Clip-on or magnetic lenses. If you wear prescription glasses, you may be able to use magnetic or clip-on lenses to turn your glasses into sunglasses.
Polarised Lenses & Sunglasses Explained
Online Opticians UK believes everyone should own a pair of quality polarised glasses or polarised sunglasses. Polarised lenses do what no other lens or lens treatment can – block blinding glare.
In addition, polarised lenses can enhance visual acuity, colour contrast and visual comfort, and block 100% of harmful UVA and UVB light.
Weve all experienced glare in our daily lives perhaps spending the day at the beach, driving in a car with the sun reflecting off the dashboard, roadway or bonnet or on a boat with the sun illuminating the surface of the water,
Usually, this glare is annoying and uncomfortable on the eyes, but when the angle of reflection is just right, the glare can become blinding and often downright dangerous, as in the case of driving a vehicle.
Ordinary tinted sunglass lenses only cut down on ambient light that reaches the eye, or, light transmittance. By their very nature, they cannot block glare. Only polarised lenses can block out this dangerous, blinding glare.
To understand how, you will need to understand how glare works and how polarised lenses work.
What is Glare?
When light bounces off of a surface, its light waves travel in all directions. Some light travels in horizontal waves, while others travel in vertical waves.
When light hits a surface, typically light waves are absorbed and/or reflected in a random manner. However, if light hits a reflective surface at just the right angle, some of the light becomes “polarized” or ‘polarization’.
