How have you found moving into your home office due to the COVID pandemic? I've had some lovely patients ask me about lighting, and I just wanted to share with you some simple information to help your eyes feel more comfortable and reduce eye strain.
Do keep in mind that it's important to have good room lighting too, so that your eyes are not continually trying to adjust between the brightness on your screen / desk, then readjusting to the light in the room, and back and forth and back and forth.
Avoid positioning your monitor right under an overhead light
Cover naked light bulbs with shades to soften and direct light away from your eyes
It's disappointing that there's so much misinformation out there about how 'harmful' blue light is, when in fact there is no evidence to show that normal amounts of blue light from excessive computer or screen use 'damages' your eyes. The amount of blue light that you receive from being on devices all day long is much less than what you are exposed to as soon as you walk outside during day light from the sun.
However, can blue light cause eye strain? In most cases, the cause of your eye strain is related to the need to take more breaks, to blink more, to wear the appropriate glasses for computer use, to have a quality anti-reflective coating on your lenses, the quality of your lenses, and dryness of the eyes. An appointment with an optometrist who has an interest in this area will determine whether glasses, eye drops, blink exercises, or a blue filter may be appropriate for you.
Read an interesting article from CHOICE here that quotes a well respected optometrist and ophthalmologist (eye doctor).
See the Royal New Zealand and Australian College of Ophthalmologists' position statement here, or watch this video from a paediatric ophthalmologist who explains the evidence and lack of evidence very well.
In this case, yes. There is evidence that blue light can affect your sleeping patterns. If you are someone that suffers from poor sleep quality, it could be worthwhile considering blue filtering apps on your devices, as well as blue filter anti-reflective coatings on lenses that are prescribed by your optometrist. Please book an appointment to have your eyes comprehensively assessed and I will advise you whether blue filters may be of benefit for your eyes.
What if I don't like the blue sheen on the lenses on blue filter glasses? There are alternative lenses that cut out blue light without the blue sheen - just ask me during your visit :)
Here's a picture of one my favourite blue filters called 21 Ray made in Taiwan. Click the picture below to see a video of me wearing one of my blue filter prescription glasses demonstrating blink exercises.
