Glasses Lens Technology for the Eyes
Digital devices and usages are increasing the demands on our eyes. Closer and variable reading distances, smaller and more pixelated characters and longer exposure to screen glare are causing tired eyes and potentially exposing our eyes to the longer-term consequences of harmful blue-violet light. As many as three out of four people feel that they suffer from visual fatigue.
Protection Against Blue Light
Eyezen is a new range of lenses designed for a connected life. It draws on extensive Essilor research, and includes two important technologies. The first: Eyezen Focus lens technology brings extra power optimized according to wearers’ profiles in the bottom part of the lens to support the eye’s effort in focusing at ultra-near distances that are typical of handheld devices. The second is Light Scan, a unique light filtering technology drawn from Essilor’s landmark Crizal Prevencia innovation, which protects eyes from the harmful blue-violet light emitted by digital screens.
Request an appointment at Eye Care Associates of Nampa today to find out if Eyezen lenses are right for you. Our Nampa optometrists will spend time with you at our Nampa eye care center and show you why Eyezen lenses represent the latest in technological innovation – both relaxing eyes from digital eyestrain and contribute to protecting visual health over the long-term.
Computer Vision Syndrome
Computer Vision Syndrome is an increasingly common condition as digital devices become more ingrained into our daily lives. Computer vision syndrome (CVS) results from extended exposure to digital screens such as computers, smartphones, tablets and televisions. A combination of factors including the blue light radiation emitted from the devices and the pixelated content that is difficult for our eyes to focus on, contribute to the effect these devices have on our eyes.
Symptoms of computer or digital eyestrain tend to be noticed after someone has used a digital device for as little as 2 hours a day. Studies show that 60% of people spend more than 6 hours a day in front of a digital device and 70% of adults report some symptoms of computer vision syndrome (CVS) which include:
- Blurred or double vision
- Physical and mental fatigue
- Dry or watery eyes
- Red or irritated eyes
- Difficulty focusing
- Sensitivity to light or
- Neck, shoulder or back pain (caused by compromised posture to adjust to vision difficulty).
Digital eye strain also impacts your ability to focus and lessens productivity. Most people do nothing to ease their discomfort from these symptoms because they are not aware of the cause. However, our Oaklawn eye doctors have several tips to help you reduce the damage done to your eyes by blue light.
Protecting Your Eyes from Digital Eye Strain and Blue Light
There are a number of options for reducing digital eye strain and your exposure to blue light which include workspace ergonomics, computer glasses, specialized lenses and protective coatings. The first step is to get a comprehensive eye exam, making sure you speak to your eye doctors in Nampa about how often you use a computer and digital device. This will help our eye care team to get the full picture of your eye and vision needs in order to determine which option is best for you. It was also help the doctor to identify any underlying issues that could be worsening your symptoms.
Alleviating Digital EyeStrain
Proper Lighting and Screen Brightness: You want the screen to be as bright as the surrounding environment or the brightest object in the room (depending on what is most comfortable for you). Therefore interior lighting or sunlight from the outdoors should be dimmed or blocked. Use fewer light fixtures or lower voltage light bulbs and close curtains or blinds when possible. Adjust the brightness and contrast of your monitor to the levels that are most comfortable.
Reduce Glare: Glare is a significant cause of computer eyestrain so it is important to minimize it as much as possible. Set up your computer where glare from windows won’t affect your screen or cover windows when this is not possible. Glare can also reflect from walls and shiny finishes on desks and other surfaces. An anti-glare screen on your monitor or an anti-reflective (AR) or anti-glare coating applied to your eyewear can also help to minimize glare and the strain it causes to your vision.
Screen size and distance: You want to make sure you are using a high quality (such as a flat LCD) screen that has a relatively large display (look for a diagonal screen size of at least 19 inches) and is located directly in front of your line of vision. Your viewing distance should be about an arm’s length away with the top of the monitor at about eye level or slightly below.
Keep Eyes Moist: When viewing a digital screen or monitor for an extended period of time, we tend to blink less frequently (about ⅓ as often as we should). Blinking however, is critical for keeping the eyes moist, which allows them to remain clear and comfortable and to avoid dry eyes, irritation, blurry vision or eye fatigue.
Focus on blinking by setting a timer for every 20 minutes and slowly closing and opening your eyes 10 times. Keep a bottle of artificial tears handy to use when your eyes are feeling dry.
Give Your Eyes a Break: Schedule and take frequent breaks from your screen. Follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. Take this time to stand up and stretch your back, neck and legs as well.
Computer glasses reduce eye strain by adjusting the focus slightly so your eyes feel like they are focusing on something further away. They also have a tint to remove the glare and block blue light from entering into your eyes. There are a number of options for computer eyewear, both if you need prescription eyewear and not. Speak to your eye doctor about what the best options are for you.Learn more about computer glasses here.
It is important to know that both adults and children alike are susceptible to computer eye strain from computers and digital devices. With the growing use of such devices in our everyday lives it is important to start educating ourselves and our children on how to combat the negative effects of these habits.
