All About Anti-Reflective Lenses

Anti-reflective lenses are just that. They reflect light and glare thanks to a special coating on the lenses. 

By the numbers:

  • 1% of anti-reflective lenses reflect 1% of available light. 
  • 8% of plastic lenses reflect 8% of available light. 
  • 12% of the high index lenses  reflect 12% of available light 
  • 99% of AR lenses allow 99% of available light to pass through the glasses allowing you to see more clearly than non-AR lenses. 

Benefits to using anti-reflective lenses:

  • Reduce eye fatigue from computer vision syndrome
  • Eliminate glare from overhead fluorescent lighting 
  • Improve vision when watching TV or playing video games
  • Improve your appearance - no reflection coming off the front of your glasses
  • Reduce night vision glare from oncoming traffic

How To Prevent Computer Vision Syndrome

Computer vision syndrome (CVS) is the physical eye discomfort felt by many individuals after two or more hours in front of a digital screen. Believe it or it, up to 90% of computer users can experience computer vision syndrome symptoms, which include: redness, irritation or dry eyes, blurred vision, back and neck pain, and headaches. 

How can relieve CVS symptoms? Try the 20/20/20 rule - every 2 minutes, look at something 20 feet away for 20 seconds. Try stepping away every 30 minutes or so to stretch you neck, arms and shoulders too. 

Ways to prevent CVS:

  • Wipe your screens regularly to reduce glare. 
  • Computer and laptops should be used at arms' length. 
  • Attach a glare reduction filter to your screen.
  • Adjust the brightness of your device. A dim screen makes it harder for eyes to focus. 
  • Screens should be directly in front of your face and below your eye level. 


What The Sun Does To Your Eyes

Those sunglasses are much more than a fashion statement. Sunglasses can shield your eyes from health problems like sunburns, cataracts, and skin cancer. 

Skin around the eyes: The skin around the eyes and, in particular, the eyelids is made up of a very thin tissues. Over time, repeated UV exposure (not to mention constant squinting) can lead to wrinkles and age spots, we well as small cancers around the eye. 

White of the eyes: Sun damage can cause a condition called pinguecula, a thickening of the conjunctiva, which is the clear, thin membrane that covers the white of the eye. This causes raised, yellow spots on the eye, near the cornea. While there's no known danger to vision, it can get irritated and inflames. The conjunctiva can also thicken and grow over the cornea, creating a condition called pterygium (also known as surfer's eye, which might obscure vision. 

Iris: Research has suggested that blue eyed people are more susceptible to macular degeneration. While as this point we don't know the exact reason, we recommend even more strongly that people with light eyes wear sunglasses. 

Retina: The retina is a light-sensitive layer of tissues that lines the back of the eye. The macula is the part of the retina where we have straight ahead and detailed vision. That macula can start to deteriorate, causing a condition called macular degeneration, leading to blurred vision or a blind spot. Some information suggests there could be an association between UV light and macular degeneration. 

Lens: Behind the iris of the eye is a crystalline lens that helps focus light onto the retina. That lens can develop a cloudiness, which is known as cataract. UV light has been implicated in the development of some types of cataracts. 

Cornea: Here's a common summertime scenario: People go to the beach for a day and as they are driving home their eyes feel kind of gritty, like maybe there's sand in there. By 10 p.m. they are in agony and by 11 they've landed in the ER for a sunburned cornea, which can cause tremendous pain and blindness. 

You can avoid all of these issues in the future by just wearing your sunglasses!

Soaking Up The Sun May Not Be A Good Thing

Now that summer is here, most people will be spending more time outdoors. Which is great! We want to give those eyes a break from computers and TVs as much as possible, but you need to remember to protect your eyes while outside. 

UV rays are present everyday of the year, even on overcast days. UV damage to the eyes is cumulative and often irreversible, but so easy to prevent! Always make sure you have UV rated sunglasses on and a hat too to help block the sun's rays to protect those eyes. Your eyes are the only internal tissue that is exposed to UV rays. 

Children and individuals who have light colored eyes are most at risk to UV damage. Some studies even show that UV rays may be tied to:

  • Cataracts
  • Eye cancer
  • Temporary sun blindness
  • Growths on the eye 

So make sure you cover up and protect your eyes this summer with sunglasses and a hat!

How To Keep Your Eyes Healthy At Work

In an office job, you're likely to stare at a computer screen for 7 hours a day. That's 35 hours a week and 1,820 per year. On top of that, when we get home we tend to use smartphones, televisions, tablets and laptops. Our eyes never seem to get a break from digital devices. There are some things you can do, however, while at work that can help alleviate the change of computer vision syndrome (CVS). 

Having a bad desk layout is on of the most common causes of CVS in the workplace, yet it's actually the easiest to fix. The top of your monitor should be at your eye level or just below it, and should be an arm's length away. 

When staring at a monitor all day, it's important to give you eye muscles a chance to relax. Take short breaks throughout the day like walking to the printer, making a cup of tea, or chatting with a coworker. If you can't get up or take a long break, remember the 20/20/20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds. 

Brightness in the office can make a huge difference too. Your monitor should not seem any brighter or any darker than the lighting in your office. If you're struggling to read what's on your screen or your screen is an obvious light source, your need to change settings. Lastly, you can use an anti-glare screen filter to reduce the amount of light reflected off your screen.
