Blue Blocker Glasses

High-energy visible (HEV) light (commonly called blue light) makes up approximately one-third of all visible light. The main source of blue light is sunlight, but the screens of our computers, tablets, smartphones, and other digital devices emit a sizable amount of blue light too. This amount isn't enough to present any immediate danger, but spending a large amount of time in front of screens (or looking too closely at them) is what may have a negative long-term effect on our eyesight.

Although we try to lower our exposure to screens, this can be challenging particularly in today's context when we are dependent on them for all activities. An easy way to prevent damage is the 20-20-20 rule- this means that every 20 minutes, you spend at least 20 seconds looking at something 20 feet away. It helps but isn't enough and work shouldn't come at the expense of health. Good digital wellbeing habits and a good quality pair of blue light blocking lenses help to filter out this harmful light and ease the strain on the eyes.

If you, like most of us, spend much of your day in front of a screen, you might need blue light glasses. They help to protect your eyes from digital eye strain and can prevent computer vision syndrome. We like blue light glasses, as they protect your eyes from the blue light emitted from the screens without compromising your vision.

Blue-light blocking glasses are designed with filters in their lenses. These filters may reduce, block or absorb blue light, preventing retina exposure to this type of light. Thanks to this technology, it has been reported that blue light glasses could minimize the side effects of prolonged screen use such as insomnia, digital eye strain, and headaches.

Blue light glasses may help protect your eyes from the blue light rays emitted by most digital screens.

Blue light blocking glasses can be worn any time you're in front of a desktop monitor or laptop computer. We also recommend using blue light glasses when using your mobile devices such as a smartphone and a tablet.

It is fine to wear blue light glasses all day and doing so should not cause any negative effects to your vision. In fact, wearing blue light glasses all day may actually help protect your eyes.

Blue light glasses are safe for your vision and should not cause any damage to your eyes. On the contrary, wearing blue light blocking glasses is possibly one way to protect your eyes from blue light.

Blue light glasses should not hurt your eyes the first couple of times you wear them, however there's a slight period of adjustment especially if you've never worn any kind of clear glasses before.

Purchasing your glasses from a reputable brand is the best way to ensure that they come with a blue light protection as promised.

In the early days of blue light glasses, the lenses were a distinct yellow, and the frames were notoriously uncool. However, these days, blue light glasses are super-stylish and designed to only filter out blue light at the higher end of the spectrum. The lenses are not noticeably yellow at all. So, while they are imperceptibly yellow (and have to be in order to work), no one will ever know, unless you tell them.

Generally speaking, you should look for the same things you look for in any pair of glasses. Start by choosing frames that are the right size for your face shape. Then, find a pair of blue light filtering glasses that match your personal style. If you need reading glasses, consider a pair of glasses with SightRelax lenses. If you wear prescription glasses, you can just add a blue light filtering feature to your prescription at checkout.

Only if you need a prescription normally. If you don’t need prescription glasses to begin with, you don’t need a prescription for computer glasses. Blue light filtering glasses, also known as computer glasses, can be bought with both prescription and non-prescription glasses.

Blue light blocking glasses are, as the name suggests, used for the sole purpose of blocking blue light from screens like computers and smartphones. While they work for those who don't require any vision correction, blue-blocking lenses are also suitable for those who:

• - Need prescription eyewear for presbyopia.
• - Wear reading glasses.
• - Wear progressive lenses.
• - Wear bifocals.

Blue light glasses are also great for people who have visual impairments over intermediate distances and want to achieve a sharper focus and enhance visual clarity. At Optical4U, we're proud to offer a variety of lens customization options for your blue-blocking prescription lenses to maximize your eyesight and comfort. These include scratch-resistant, anti-reflective, UV400, and superhydrophobic coatings, all purpose-built to protect your glasses (and your eyes) from everyday stresses and strains.

Digital eye strain, or computer vision syndrome, is discomfort that usually occurs after a few hours of screen usage. As previously mentioned, most digital screens emit blue light that can be harmful to your eyes. Excess exposure to blue or high-energy visible (HEV) light may also lead to other eyesight problems in the long term.

Computer vision syndrome symptoms include:

• - Dry eyes.
• - Eye fatigue.
• - Watery eyes
• - Burning sensation
• - Blurry vision.
• - Pain in the back, neck, and shoulders.
• - Headache.
• - Difficulty concentrating.

Many of these symptoms can be alleviated by using the right sort of glasses. As we've said, blue light blocking lenses are designed with preventing these symptoms in mind. Luckily, we offer an effective solution over at Optical4U...

By blocking blue light, you let your bod's normal hormonal rhythm take place, an especially important factor for getting a good night's sleep. Not only do blue light glasses reduce digital eye strain, but they also allow your body to take its natural cues only from the sun, rather than deceptive screens.

Blue light glasses have been shown to reduce the impact of this spectrum on macular degeneration.

At Optical4U, we're not just committed to bringing you the latest and trendiest eyewear. We're also dead-set on improving people's eye health with our blue light blocking glasses. If any of the symptoms mentioned above apply to you, or you spend hours in front of screens and are interested in checking out some of the fastest-growing subsectors of the eyewear world, we highly recommend blue light glasses.
