Flashy headlights can cause severe road accidents at night. Because of this, people now prefer to use night vision glasses. But then again, do night vision glasses work? Are they really effective? Let’s find the answers in this article.
Most of the time, people drive their cars with high-beamed headlights during the night. The headlights of the car coming from the opposite side are often bright enough to dazzle you. In fact, they can even blur your vision for a second, which results in accidents.
To reduce the effect of headlights at night, drivers are now using night vision glasses.
Night vision glasses, as the name reflects, are glasses designed to work at night. These glasses have yellow-colored lenses that are, most of the time, polarized.
Night vision glasses cannot replace your prescribed glasses, though. In fact, you can wear your eyeglasses underneath night vision glasses (with some options). This is because the bulkiness of night vision glasses can help you to adjust the eyeglasses under them.
Sometimes, people confuse night vision glasses with night vision goggles. Yet, there is a huge difference between these two. Night vision glasses help to dim the brightness of headlights and other flashy lights at night.
On the other hand, army or law enforcement agencies use night vision goggles. These goggles have infrared lenses that help the person to see clearly even in low-light or no-light conditions. Night vision goggles increase and amplify the available light. This is how they make the vision clear.
Night vision glasses work in the following ways:
According to the manufacturers of night vision glasses, the yellow color of the lenses helps in reducing the brightness of flashy lights. This is why almost all models of night vision glasses come with yellow lenses.
Furthermore, the yellow lens also adds a little bit of hue to the white light since all the headlights have white light as their major light composition. The bright white light looks sharp and dazzling at night to the naked eye, but not in front of the yellow lens. The yellow color helps to see things clearly at night without altering the color spectrum too.
These night vision glasses are also effective in hazy and foggy days and even at the twilight period of the day. The yellow color increases the contrast of colors, so it becomes easy to perceive depth and distance.
Most night vision glasses come with polarized lenses. These lenses help to reduce the reflection of light at night. However, according to manufacturers of night vision glasses, these polarized lenses are different from those that come in sunglasses.
Blue light causes our eyes to strain when we look at LEDs, flashlights, headlights, or neon lights. Sun emits blue light with all the other lights as well. This blue light is present everywhere, which blurs the vision at night. Our eyes sometimes cannot filter the blue light at night.
Night vision glasses block the blue light that blurs our vision at night. In turn, they help to improve our vision during nighttime.
It has been a long debate whether night vision glasses are just a fashion trend or do they actually work. Most of the eye specialists consider night vision glasses consider effective while some see them as an obstruction to night vision.
In addition, it is also said that the polarized lenses of night vision glasses reduce the transmittance of light. Hence, most of the ophthalmologists suggest that it is better to wear night vision glasses as they make it safer to drive at night.
Most of the night vision glasses have similar features. Few of them are:
To ensure the maximum durability of night vision glasses, the frames of these glasses are mostly made of up stainless steel or aluminum magnesium alloy.
These glasses are always designed in a stylish way. Most of the brands have different designs for men and women while some are unisex.
The lenses of night vision glasses protect your eyes from the harsh and bright light. They are coated with different films that save your eyes from the UV rays of the sun so you can wear them even in broad daylight.
The aluminum frames are lightweight and comfortable. Night vision glasses made up of aluminum alloy are easy and light to wear too. Some are also made of plastic, but they are not as durable as aluminum frames.
The micro-infused lenses of night vision glasses increase the contrast of colors, so it becomes easy for you to distinguish colors at night.
Most of the brands offer a scratch-resistance feature. Their lenses are coated with dual scratch-resistant layers that protect the lenses and save them from any scratch.
If you’re buying good-quality glasses, the lenses should be shatterproof. They are made up of either German resin or polycarbonate coating, which also adds strength to these glasses.
There are many other precautionary steps that you can consider if you are having problems driving at night. Precautions are better than wearing the night glasses, after all. These glasses can also have negative impacts on our eyes if overused.
What you can do to improve night vision include the following:
Night vision glasses are trendy nowadays. You can buy them easily from any reliable source either in physical stores or online. However, it is better not to overuse them and keep them exclusive for driving only.
