UV Protection Vs. Anti-Glare: What Makes Them Different?
Glare prevention is sometimes mistaken with UV protection, even though the two are fundamentally distinct. The level of glare prevention or tint depth a lens provides has no impact on how much protection from the sun it offers.
What is the distinction between UV protection vs. anti-glare lenses? Our article will help you find the answer you are looking for.
Is UV Protection Same As Anti-Glare?
Actually, no. The amount of sunlight we can see is an anti-reflective function. As a result, glare shielding is included with all dark lenses since it blocks or decreases a portion of the visible light.
However, there is an unseen component referred to as UV light. Even on overcast days when the sunshine is nearly invisible, our eyes must be kept from this. Your vision can be injured if there is no UV defense. This can take many forms, ranging from innocuous conjunctivitis or temporary "snow blindness" to the destruction of photoreceptor cells and the development of cataracts.
What Are The Differences Between UV Protection And Anti-Glare?
1. Anti-Reflective (Or Anti-Glare Spectacles) Only Increase Visibility
Back-glare happens when light hits the rear of eyeglasses lenses and is reflected into the eyes. Anti-reflective lens coatings are designed to avoid this.
Anti-glare glasses function by causing an interference pattern. It equalizes the light intensity returned from the top and bottom surfaces of the film. This tough, thin coating has a refractive index between atmosphere and glass, approximately a quarter of the light spectrum.
The complete spectrum of light waves, particularly blue light, can enter lens treatments created to stop glare and reflection. This film is designed to enhance eyesight clarity.
Wearing glasses with this coating will reduce the harmful effects of glaring, lower eye strain, and improve vision. Anti-reflective lens treatments on spectacles may benefit various applications, including screen use and night driving.
Thus, the color of the lenses and glare prevention should not be mistaken with UV protection. This filter doesn't block UV rays. But it does reduce glare, which is why it is necessary for decent sunglasses.
Glasses with filters type 0 or 1 do not give enough glare reduction. However, spectacles with a type-2 filter can do the trick. And eyeglasses with a category-3 filter offer excellent glare protection. Since they darken far too much, glasses with a filter type 4 are still not allowed in traffic.
Hence, pay close attention to the filter category while selecting your spectacles.
2. UV Protection Can Block UV Rays
If you've ever had a sunburn, you're well aware of the dangers that the sun poses to your skin. When exposed to unfiltered radiation, the sunlight not only harms your skin but also harms your eyes. This is due to the so-called ultra-violet radiation (UV rays).
The sunlight emits light waves and UV rays invisible to the naked eye. The ozone layer filters UV-C rays. But approximately 10% of UV-B rays and nearly 100% of UV-A rays hit the earth's surface untreated, relying on the ozone layer.
The intensity of Ultraviolet radiation is also affected by several elements, including your season, latitude, time of day, or altitude.
The equator receives the most radiation. It is also more powerful in the summertime than wintertime, around midday than in the mornings and evenings. Per 100 meters of height, UV radiation rises by about 10%.
A major portion of UV radiation is shielded in severe weather with high cloud cover. However, with mild cloudiness and fog: UV radiation is boosted!
UV radiation is also increased by water, sand, and snow since they reflect it.
If you're purchasing sunnies or sports spectacles, ensure they're UV-protected. Shades should absorb UV radiation up to 400 nanometers in wavelength, protecting the eyes from dangerous UV-A or UV-B rays. The marking UV400 and 100 percent UV protection may help you identify them.
3. Anti-Glare Glasses Are Suitable For People Who Want To Improve Visibility And Minimize Brightness
Glare is an overabundance of brightness created by straight and reflected light. As the sun's rays bounce off a reflecting surface like water and snow, this phenomenon happens. Glare can also be caused by LED-lit phones, tablets, and computer screens.
Everybody can benefit from anti-glare sunglasses. It’s because as the anti-reflective film decreases, any light bounces from your eyeglasses. This is particularly helpful for individuals who:
- Work with computers regularly since extended computer use might tire their eyes.
- Typically drive, whether at nighttime (when brightness from approaching traffic might make it difficult to see) or during the day (as bright sunlight may cause a similar impact.)
- Work in direct sunshine.
4. UV Protection Are Suitable For People Who Are Often Exposed To Sunlight
Three major user profiles that require UV protection include:
- Workers in the construction and outdoor industries. Employees who work outside are susceptible to ten to twenty percent more UV light than those who work indoors.
UV radiation would be most powerful from 10 am to 4 pm. This period corresponds to the average hours of a dayshift or weekday. So it's easy to see why outside laborers should prioritize protection from the sun.
- Enthusiasts: Many people love playing outside even if they do not work outside. UV protection is particularly necessary for outdoorsy types who spend countless hours outdoors after work and on weekends.
- Children: Every parent understands the significance of sunscreen for their kid's skin, yet, how about the eyes? Children, who stay longer than adults, are another target group requiring UV-blocking glasses.
Until these last lines, the post has given you helpful information regarding the topic of UV protection vs. anti-glare.
Glare protection is the process of protecting the eyes from incoming light using tinting and polarizing glasses, for example. It’s to lessen discomfort from reflections off slippery roads or ice.
Meanwhile, the UV layer on spectacles and eyewear can shield your eyes from dangerous UV rays. Luckily, glasses can now prevent both UV and glare, which we highly recommend.
