The truth is, blue light isn’t all bad. It shouldn’t be blocked at all times. It can help memory, boost alertness, and elevate your mood! Still, the eye cannot take blue light all day long and it can easily contribute to eye strain especially when it is coming from computer screens and iPads and cellphones.
These days, we’re working, learning, and relaxing in front of screens emitting blue light all throughout the day—and night. Even your average indoor lightbulb can give off blue light.
You’re probably wondering. Okay, but what is blue light anyway?
Blue light is the highest energy visible light on the UV spectrum, and prior to the advent of technology, the sun was our only significant source of blue light. Problems arise, however, with the amount of blue light to which we are exposing our brains and bodies, potentially causing undue stress to our eyes and even making it hard to sleep at night.
There are a few ways to avoid this strain. First, let us introduce you to one of the best options on the list: blue light blocking lenses.
What are blue light blocking lenses?
Good question. Glasses equipped with lenses with blue light protection are a simple solution to combat the symptoms caused by increased screen time. The technology in these lenses has a subtle tint that softens harsh blue light rays as they pass through, reducing the amount of blue light to which the wearer’s eyes are exposed. They aren’t heavy or thick and can be made without a prescription attached to them. They can be made to fit adults, teens, and children and are safe for all to wear. All blue light blocking glasses aren’t made the same. They can be made to block a certain percentage of blue light. How much you decide to block, well, that is up to you. Give our practice a call and we will gladly talk you through your options!
What else can I do to block blue light?
While you won’t be able to block it without the correct lens as your shield, you can still manage it.
When working at a computer, for example, you’re often looking up and down, from screen to paper, and your eyes are moving around and refocusing time after time. This is where the 20-20-20 rule can come into play. For every 20 minutes you’re in front of a screen, turn your head and look at something at least 20 feet away for 20 seconds. Just, give your eyes a break.
Another option: simply lower the brightness. The display settings for your screen on your phone or computer allow you to adjust the amount of light seeping from the screen. If your screen looks like a light source, lower the brightness. If your screen looks dull and a bit too dark, it’s okay and probably for the best to brighten it up. A dull screen can also strain your eyes.
Bottom line, protect your eyes the best way you can, and remember that we are here to help! Looking to get a pair of blue light protection glasses that fit your lifestyle and your budget? Here at Karoo, we can customize any style of frame and lens prescription with blue light blocking technology.
Fun fact: 80% of the sensory information that reaches our brain comes from our eyes.
With so much uncertainty as our kids, teens and young adults go back to school this fall, one thing is for sure… our eyes are remarkably important to learning. Not only does 80% of the information to our brain come from our eyes, but also 80% of learning is through our eyes.
Learning and behavioral disorders should not be impulsively assumed without investigating the full spectrum of eye health, especially since vision and eye health issues are not always obvious.
Children who can see well outside of class may still struggle with their vision while learning. Eye alignment, eye teaming, eye movement and coordination, eye focus and dry eyes all influence how we all visually perform.
Take this story, for example. A New York Times article published by Laura Novak in 2007 narrates about a young girl who was prescribed three medications for attention deficit disorder and depression only to find out later that she had been living with convergence insufficiency since birth.
Convergence insufficiency, as outlined by the Mayo Clinic, is a condition where your eyes are unable to work together when looking at nearby objects. It can cause difficulty reading, resulting in school-age children promptly deciding to close the book and take on a new task, making it understandable for a parent to conclude that attention deficit is the dilemma.
Parents and educators alike often assume that if our child passes a vision screening, they are ok. Vision screenings are not comprehensive eye exams.
Vision is a sense that is not always automatic. It develops in our formative years, between birth and eight years of age. Comprehensive eye exams can detect issues that once addressed, can have lifelong impacts. For school-aged children, the American Optometric Association recommends annual eye exams begin before 1st grade and are maintained each year thereafter.
Let’s give our children the best chance at success! Make sure you get your child’s annual eye health and vision exam checked off your list!
Countless people around the world wear daily disposable contact lenses or dailies. These popular single-use lenses are removed and discarded at the end of each day, and a new, fresh pair is inserted the next morning. Used properly, dailies promote eye health, and they’re comfortable and convenient.
Despite the many advantages associated with wearing daily disposables, keep in mind the following tips to help maintain proper eye and vision health.
1. Don’t Touch Contacts with Dirty Hands
Before touching your lenses, make sure to wash your hands thoroughly with soap and water. By touching your contact lenses with dirty hands, you transfer bacteria to your lenses, which can lead to an infection. Preferably dry your hands with a disposable paper towel rather than a cloth towel and ensure that no remnants of the towel remain on your fingers.
2. Don’t Expose Your Contacts to Water
Any source of water, whether tap, pool, or lake water, can change the shape of your lenses and cause micro-abrasions on your cornea. Plus, the water may contain bacteria that can wreak havoc on your eye health and cause you to experience temporary vision loss or even permanent blindness.
If you must get in the water with your contacts on, make sure to wear waterproof goggles. If you do get water on your contact lenses, dispose of these lenses and insert a new pair. Exposing contact lenses to chemicals like chlorine binds to the lens and cannot be cleaned off. It then leeches onto the cornea and causes irritation.
3. Don’t Reuse Your Contacts
Daily disposable contacts are designed to be thrown away after every single use, and people who reuse them risk painful and risky outcomes. Dailies are thinner, more fragile, and don’t hold moisture as well as other contacts.
Users sometimes attempt to increase the lifespan of these lenses by cleaning them in a disinfecting solution and wearing them for several days or even weeks at a time. This is problematic, as the lens material doesn’t allow for repeated disinfecting. In fact, the process of cleaning the lenses tends to be not only ineffective, but it also breaks down the lens itself, increasing the risk of it falling apart while in the eye. The risk of complications and infection is not worth the few saved bucks.
4. Don’t Insert a Dropped Contact in Your Eye
One of the perks of daily lenses is that they are less expensive (per lens) than other types of contacts. So, if you find yourself dropping a lens into the sink or on the floor, don’t bother placing it back in your eye. Doing so can cost you your eye health.
5. Never Put Contacts in Your Mouth
It seems like a funny concept, doesn’t it? You wouldn’t believe the number of people who do this. If you drop a contact lens, avoid rooting around the floor trying to find it, and if you do, definitely don’t put it in your mouth to lubricate it. Your mouth contains bacteria that can infect your eyes once you reinsert your contacts.
Play it safe by carrying around an emergency pair of glasses or an extra pair of daily disposable contacts in your bag, your car, or at work.
6. Don’t Overwear Your Daily Lenses
Wearing your lenses for long periods of time can damage your eyes, even if they’re daily contacts. The maximum recommended daily use for any contact lens is 14-16 hours, though your eye doctor at Karoo will determine the exact number of hours you should wear your lenses. Your eyes, just like any other part of your body, need to rest. Your corneas receive oxygen from the air, not from blood vessels, and while it’s healthy to wear contacts during the day, wearing them for extended periods can significantly reduce the amount of oxygen your eyes receive, which can lead to complications. If you don’t give your eyes the rest they need, your corneas might get swollen, which can lead to corneal abrasion and even bacterial infection.
7. Don’t Sleep with Your Lenses
Daily lenses should never be worn overnight. You’re risking your sight by sleeping in a lens that’s not approved for overnight use, as it can lead to ocular irritation, swelling, and corneal ulcers.
8. Don’t Insert Contacts Before Completing Your Morning Routine
Avoid inserting your contacts before you shower or wash your face since you risk exposing your lenses to tap water and the bacteria that come with it. We also recommend that you insert your lenses after blow-drying and styling your hair, especially if you’re using hairspray or other aerosols, as these products can dry out your contacts. Additionally, the spray can coat the lenses and leave a film that not only irritates the eyes but can make it difficult to see. If you’re at the hairdresser’s and cannot remove your lenses, shut your eyes when a spray is applied.
9. Don’t Get Makeup on Your Contacts
Insert your contacts before applying makeup, because any makeup residue on your hands, such as mascara, can easily transfer to your lenses.
It’s not uncommon for people to get concealer, eyeliner, or mascara on their contact lenses. If that happens, immediately remove the lens and clean them with a solution. Otherwise, simply replace it with another lens. Avoid wearing waterproof makeup, since it can’t always be removed from your lenses, even when rinsed with a solution.
To prevent makeup from getting on your lenses, don’t apply mascara all the way from the base of your lashes up. Instead, apply it from the midway point. It’s also important not to apply eyeliner on the inner lid of your eye, but rather to the skin above your lashes.
10. Don’t Wear Contact Lenses If Your Eyes Are Irritated
As the saying goes, “if in doubt – take them out!” If your eyes feel irritated, uncomfortable, or if you notice any pain or redness, don’t power through. If your symptoms last a while, contact us at Karoo. You don’t want to let a serious infection go unchecked.
When your eyes feel more rested and are free of discomfort, put in a fresh pair of contacts.
11. Don’t Rub Your Eyes
If your eyes feel itchy or dry, or if a lens feels out of place, you may be tempted to rub your eyes. But rubbing, whether with contacts or without, can lead to long-term ocular issues. This may cause you to experience blurred vision and may even damage your cornea. Instead, your eye doctor at Karoo can recommend eye drops to relieve any discomfort. Make sure to apply them only when contact lenses are removed.

Dr. Gavin Cohen discovered his career as an optometrist through another one of his passions, wildlife photography. Cohen, who was raised in South Africa, started photographing his surroundings at a young age and, now that he lives in Atlanta, he travels back to his birthplace several times a year for photography expeditions. While some people hunt the “big five” game animals — the African lion, African element, Cape buffalo, African leopard and rhinoceros — for sport and to collect them as trophies, Cohen photographs them in their natural habitats.
Cohen’s photographs line the walls at his two Atlanta practices, and he also sells his eye wear brand, Karoo, at his shop at Ponce City Market in Midtown Atlanta. In addition to developing a line of eyeglasses, Cohen has developed his own “orthokeratology” technique, which involves fitting patients with contact lenses they wear overnight to treat nearsightedness, astigmatism and presbyopia by actually reshaping the cornea.

When you walk into the Karoo eyewear store, it feels like you’ve stepped into an upscale travel outfitter. The walls are covered in reclaimed wood and images of far-off locations and exotic animals. Every corner of the store features travel pieces, like vintage binoculars, that seem like they came straight from a wild excursion or luggage that bears the wear and tear of being carried around the world. Even the name Karoo evokes another land far from the hustle and bustle of Atlanta. But as you peruse the boutique and see the gorgeous frames dotting the walls, even hanging from the ceiling as part of the decor, you realize this isn’t your average eyeglasses store.
