Glasses tints and filters: Why do they matter

Glasses tints and filters: Why do they matter

Tinted glasses move in and out of style all the time. But, apart from enhancing your street fashion, they do a great deal for your eyes and vision protection. With the right tint or glasses filter, you can experience the best vision quality and block some harmful lights.

If you think that lens tints and filters are only for increasing the cost of your glasses, you’re wrong. They are available to improve your overall visual experience and give you a sharp vision.

Whether you use digital screens a lot or you drive frequently, there are different glasses filters and tints ideal for different activities.

Glasses Filters

Blue Light Filter

The most common filter for eyeglasses is an anti-blue light filter that is designed to block blue light when doing computer work. The most common cause of eye strain from looking at digital screens is the damaging blue light that these screens emit.

People often find their eyes sore and dry after locking their gaze on a screen for a long time. This is all because of the blue light as it’s unfocused which creates visual noise and your eyes struggle to focus on the screen.

Although sunlight is the biggest source of blue light, it’s all-natural and thus has more benefits than threats to our health. But, the blue light coming from your devices isn’t natural and long hours of it causes eye strain, dry eyes and sleep loss.

The blue light emitted from electronic devices is only a fraction of that emitted by the sun, but the number of time people spends using these devices often means their eyes are exposed to a large amount of this radiation. Blue light filters in glasses help block out the majority of this blue light radiation before it reaches your eye.

Blue light protection glasses are equipped with an advanced coating that blocks the blue light and prevents eye strain no matter how long you’ve been on your devices. While it’s not scientifically proven, but some experts believe that constant exposure to blue light can lead to retinal damage over time. Thus, blue light glasses are able to prevent that damage as well.

Ultraviolet filter

Blocking the UV rays is the most effective way to keep your eyes healthy for as long as possible and also cut down the risk of certain eye conditions.

Sunlight contains UV light that’s just as damaging to your eyes as it is to your skin. Intense exposure to UV rays can cause photokeratitis or sunburn of the eyes.

Also, long term UV exposure can also increase your chances of developing cataracts or macular degeneration.

If you have sunglasses, you might be wondering why you need UV filters on your prescription glasses as well. But, it’s important to know that UV rays are just as intense on a cloudy day when wearing sunglasses won’t be a practical choice.

Adding UV treatment to your prescription lenses is one smart way to ensure that your eyes are protected from UV damage all the time.

Different lens treatments for UV protection

1. Sun tints

Adding a tint to your lenses offers UV protection to your eyes but enhances your view as well. Tinted lenses can soften harsh or bright lights and relieve eye strain. Not only outdoors, but tinted prescription glasses will protect your eyes from bright indoor lights as well

2. Polarisation

If your vision gets interrupted by glare or bright reflections, then you can use eyeglasses with polarised lenses. These lenses block UV light and also eliminate glare by blocking light reflections from flat surfaces such as a wet road or water.

3. Photochromic solution

Photochromic or transition lenses darken up in the presence of UV light. If you move between indoors and outdoors, you probably need glasses that can work as sunglasses. Well, your search ends here as transition glasses are the end to your misery.

Where the lenses stay crystal clear under indoor lighting, they assume a dark tint when you’re exposed to UV rays. Thus, you only need these glasses to protect your eyes both indoors and outdoors.

Anti-Glare Filter

Anti-glare filters block the bad light and only let good light interact with your eyes. It filters out the light reflected from digital screens or from a flat surface. It improves the quality of your vision by reducing the number of reflections on the lenses.

This coating is available for all lens types including bifocal, varifocal, high-index or standard lenses.

Anti-glare filters also improve the profile of your glasses. When you’re in bright light settings, the reflections on your lenses can prevent people from seeing your eyes. But, this filter solves that problem and give a nice look to your eyeglasses.

All of the sports glasses have this filter, especially the ones used in snowboarding, fishing or skiing.

Anti-Scratch Treatment

Anti-scratch is the most important feature in any pair of glasses. It’s a tough coating that’s applied on the surface of the lenses which makes them resistant to scratches.

As you wear eyeglasses day-in-day-out, it’s normal to drop your glasses that can damage the lenses. This won’t only ruin the look of your specs but you’ll also have to deal with poor vision pertaining to lens imperfections.

If you want your lenses to look as good as new for a long time, we recommend you get an anti-scratch treatment for your glasses. All the prescription or non-prescription glasses at Specscart have this coating along with anti-glare and UV treatment. And the best part is that these coatings are free or complimentary with all our glasses.

Glasses Tint

The right glasses tint can improve your visual experience by increasing contrast and depth perception. Here’s what different lens tints do for your vision.

Amber / Brown lens

They provide excellent depth perception and enhance vision in low or moderate light levels. Amber or brown tinted lenses also work towards blocking the blue light. Consider these lens colours on a cloudy day to make your vision a little brighter.

Yellow / Orange

These lenses work for both indoor and outdoor lighting conditions. They also make your surroundings appear brighter and improve the visibility of objects in low light levels.

Blue / Purple
