GROOVING TO BLUE LIGHT

What is blue light? How does it affect us? And what are blu-blockers?!

If you’re a child of the 80’s, you’d remember BluBlockers – the sunglasses that block blue light, and reduce squinting. Their unique origins came from the space program, as astronauts needed eye protection from the strong radiation of outer space. BluBlockers were designed to not only block all ultra-violet (UV) rays, but all blue rays as well. Research at the time indicated many eye diseases were caused by the spectrum light waves. Blocking the blue light decreased the danger… and so, BluBlockers were born. While a lot has changed over the past 30 or so years, some things have not. Blue light and the effect it has on our eyes, for example, is a continual topic of conversation. So we’ve decided to shine our Groovy spotlight on blue light. 

What is blue light and where does it come from?

Blue light is part of the visible light spectrum, that the human eye can see. It comes naturally from the sun and helps our body clocks determine when to do things, like when it’s time to wake up and to go to sleep. Blue light can also be found in a lot of modern technology; like smartphones, laptops, tablets, TV and artificial lighting.

What’s all the fuss about?

With the constant increase of screen time – particularly since the pandemic – more people are working from home and utilising technology to replace face-to-face meetings. This is evident even for our children, who have had to adapt to online learning, especially during lockdowns. Combined with the amount of choice we have for content these days, it’s no wonder we’re spending so much of our days (and nights) on our screens and devices. In the evenings, our natural body clocks are telling us to unwind and rest. Too much blue light exposure at this time, suppresses productions of our melatonin hormone (the one that helps us to sleep). As you’d expect, this can result in a poor night’s sleep. And we all know how much our bodies need sleep! The long-term effects of sleep deprivation are very real and can affect you physically and mentally. More on that another time…

Okay, so what can we do about it?

There are copious amounts of research about how we could all benefit from less screen time, as well as some great initiatives like ‘Phone Free Day’. Though we understand this can be easier said than done sometimes, as devices are a necessary part of our modern lives and how a lot of us earn our living.

Here’s a few things we can do to help protect our eyes:

1. Make sure you take breaks. We like the 20-20-20 eye exercise: every 20 minutes, look 20 metres away, for 20 seconds. Doing this simple eye exercise relaxes your eyes and shifts your focus, so you’re not always looking directly in front of you, at your laptop, for example. Stepping outside for some fresh air (and not switching one device for the other) is also always a good idea.

2. As well as reducing screen time before bed, you can also adjust the settings on your screen. Lots of devices these days have a night time setting, which changes the colour balance on your phone, tablet or laptop to reduce the amount of blue light you’re exposing your eyes to. Handy huh!

3. Blue light protection filters for your glasses. If you need to be on a computer, laptop or your phone for most of the day, we’d recommend blue light glasses. In the same way that we put on sunglasses when we go outside to protect our eyes, it’s important to protect our peepers when we’re using screens. Blue light protection filters do just that – filter out the blue light from all of our devices. Which means less eye strain and feeling more energised at the end of the day. You can purchase them separately or we can add them to your current prescription glasses.

4. Replace cooler/brighter (blueish-white) lightbulbs with warmer (more yellowish- white) lightbulbs.

VISITING GROOVY GLASSES UNDER “ORANGE”

Groovy Glasses is an essential primary healthcare provider, and so continues to offer a comprehensive and equal service to all regardless of vaccination status.

At Groovy Glasses, we’re passionate about keeping our customers and our teams safe. To do this, we need your help, please read below for more info: 

If you answer YES to any of the following, please call us on 03 3798 747 before heading to the practice, so we can make any necessary arrangements. 

  • Do you have a mask exemption?
    • If YES, please phone us on 03 3798 747. One of our optometrists will call you to discuss a tailored approach for any necessary treatment.
  • Do you, or anyone in your household, have any of the following symptoms?
    • Fever
    • New cough
    • New breathlessness
    • Sore throat
    • Cold symptoms / runny nose
    • Loss of sense of smell
  • Are you, or anyone in your household, awaiting a COVID test result?
  • Have you had a household contact with a confirmed COVID 19 case in the last 7 days? 

When you come instore for eyewear or for any other products: 

  • Face covering. To keep us all safe, all customers and patients over the age of 6 years will be required to wear a disposable surgical mask. If you don’t have a disposable surgical mask, we will happily provide one for you. 

When attending an appointment:

  • Face covering. To keep us all safe, all customers and patients over the age of 6 years will be required to wear a disposable surgical mask. If you don’t have a disposable surgical mask, we will happily provide one for you. 
  • Hand washing or sanitiser. When you enter Groovy Glasses, please use the hand sanitiser provided. This is the most effective way to reduce the transmission of germs, and we appreciate your co-operation.
  • Appointments will run on time. We’ll be making sure we run on time for your appointment, and we ask that you do the same. If you are late for your appointment, please understand that we may have to: a) perform a shorter appointment or b) reschedule your appointment. Having staggered appointments running on time reduces cross-over between patients and allows our practitioners time to perform the disinfection protocols between patients. 
  • Our waiting areas. If you are on-time for your appointment, please come straight in – we will be waiting for you 🙂 If you are early for your appointment, please wait outside or in your car until your appointment time. This reduces the number of patients in our clinical space and helps with social distancing in our waiting areas. 
  • One support person at your appointment. If required, please bring only one support person to your appointment. Your support person must follow the same guidelines as all of our customers (detailed above) and must not be unwell or require isolation. At this time, children are not able to attend your appointment or wait in the waiting area during your appointment. If the appointment is for a child, a parent or guardian is encouraged to also attend, but we do ask that only one parent or guardian attends; no siblings or friends please.  
  • Namaste. No offence, but we’re not shaking hands, hugging and refraining from physical contact as much as possible. Instead, we may welcome you with a namaste to share a little peace and calm. 

Of course, these measures are in addition to the already stringent hygiene standards we are upholding. We do ask for your help in keeping our community safe. Our clinics regularly care for the elderly, infants and those with complex medical conditions.

We ask you to please take the proper health precautions when visiting us, and to reschedule your appointment if you or a family member is either unwell and/or is awaiting a COVID test result. 

We appreciate your support through these difficult times, and we know that we can all get through this together again. 

See you soon, 

The team @ Groovy Glasses
