The Science Behind Night Sunglasses

Sunglasses protect your eyes from the damaging rays of sunlight and can alleviate glare and light sensitivity. For best results, choose sunglasses with a dark tint and polarization, which reduces glaring reflected light.

Behind Night Sunglasses

Yellow lenses help reduce glare by filtering some of the blue light most likely to cause eye strain. These lenses also enhance contrast in certain daylight conditions.

Reduces Glare

Whether driving at night or just enjoying the outdoors, eye strain caused by bright lights can be a problem. The good news is there are solutions to help ease the discomfort and protect your eyes.

Most glasses, like sunglasses at night that claim to enhance night vision, are marketed without a prescription. These typically include polarized or UV lenses with a yellow tint.

These lenses are advertised to reduce headlight glare and improve the ability of aging individuals to see at night. However, studies show these glasses decrease a driver’s range of vision and make it harder to detect pedestrians. They also limit the amount of light entering the eyes.

Reduces Eye Strain

Many nightglasses sellers claim they are effective at reducing headlight glare and dazzle. However, studies have shown that these yellow-tinted glasses reduce your visibility by restricting the amount of light that reaches the eye.

For the best results, look for lenses with a non-glare coating, like Visionworks Elite Non-Glare. This will reduce reflections both at night and during the day. They also filter out blue light, which can cause digital eye strain and improve contrast in low-light conditions. These lenses also come with a microfiber cloth and protective EVA case, making caring for your eyes easy. These sunglasses also have photochromic lenses that change from transparent to dark when exposed to UV light.

Reduces Eye Fatigue

Many products on the market claim to help reduce eye fatigue. They typically have a yellow tint that filters out blue light and boosts contrast. The idea is to make it easier for your patient’s eyes to adapt to low light conditions after sunset and to avoid glare from oncoming car headlights while driving.

However, the best solution is polarized sunglasses that filter out blue light and reduce glare. They’ll still allow your patients to see in the bright sunlight without delay and can prevent night vision degradation from overexposure to blue light from the sun. Then, when it’s dark out, their eyes will be accustomed to the darkness, and they’ll have better night vision.

Reduces Eye Damage

Many types of glasses are sold that claim to enhance night vision. Often, these are non-prescription sunglasses that have yellow polarized lenses. They also can reduce glare, make objects appear more evident, and help you see colors more accurately.

Eyeglasses that filter out high-energy visible (HEV) blue light can protect your eyes from the harm caused by digital screen glare. They do this by obstructing blue light from electronic devices such as smartphones and tablets.

You can find these blue-light-reducing eyeglasses in various tints and frames. They are a popular choice for people who use electronic devices regularly. They can also reduce glare from headlights and streetlights while driving at night.

Reduces the Risk of Macular Degeneration

Many people wear sunglasses daily to protect themselves from the sun’s harmful rays. However, these same glasses may negatively affect their night vision by making it harder to adjust to changing light conditions and increasing the glare of headlights and streetlights. Look for polarized lenses that block UV and reduce glare to minimize these effects on your night vision.

In addition to wearing polarized sunglasses, you can decrease your risk of eye damage by limiting screen time and using screen filters that reduce blue light and increase contrast. Talk to your eye doctor or optician to learn more. They can help you find the right sunglasses for your lifestyle and needs.

Reduces the Risk of Cataracts

Many eyewear companies offer products that improve night vision by decreasing glare from headlights and streetlights. These glasses typically use a yellow tint and may contain UV or polarized lenses.

Cataracts are a common eye condition that causes blurry vision and faded colors. Exposure to UV rays can accelerate cataract formation, so wearing sunglasses that protect your eyes from the sun is essential.

Expert ophthalmologists recommend wearing polarized sunglasses that provide 100% UV protection. They should also screen out 85% of visible light. The shape of the lens is also essential, as it reduces reflections from horizontal surfaces such as water and snow. This increases eye protection even on cloudy days.

Reduces the Risk of Glaucoma

Some people find it difficult to see in low-light conditions, known as night blindness. This condition is called nyctalopia, and it can be caused by eye diseases such as cataracts, myopia, or Retinitis Pigmentosa. It can also be a side effect of certain medications, such as blood pressure medication and high blood sugar levels.

Specific lens tints can help with this. Tinted lenses cut glare from artificial and natural light. You may need to experiment with different tints until you find one that works. Some frames come with a clip-on polarizing filter to attach to your glasses. This is an excellent option for those who have trouble seeing in low-light conditions and want to reduce glare while driving or during outdoor activities.

Reduces the Risk of Eye Cancer

People with poor night vision use yellow-tinted glasses to reduce glare from oncoming vehicle headlights. This approach works by scattering and filtering out blue light with the shortest wavelength, increasing contrast for better visibility. These glasses are also popular with hunters to help them see the colors of flying birds in low-light conditions.

Poor night vision can be caused by age-related macular degeneration, vitamin A deficiency (from a lack of dark greens and oranges in your diet), diabetes, or a medical condition like retinitis pigmentosa that destroys sensitive cells in the retina. Other causes include a faulty corneal shape, astigmatism, and post-LASIK complications.

The best way to improve your eye health is to wear sunglasses with 100% UV protection and wraparound frames that fit close to the eyes. This will limit your exposure to reflected sunlight and snow, which can burn the delicate skin around your eyes.
