Ocushield & Optometry – Looking After Our Eye Health in the Digital Age
If you are an Optometrist in the UK, or have recently watched Dragon’s Den, the name Ocushield may be familiar to you. Their Medical Grade blue light filter is available across businesses in the healthcare industry such as Superdrug Opticians, as well as in popular retailers, such as Urban Outfitters and Nordstrom. Their products work to protect our eyes from strain and eye health issues. Whatever your knowledge of the brand and its products, we are here to help you. We have created a useful guide to Ocushield and looking after your eye health in the Digital Age.
What is blue light?
According to Ocushield, blue light is everywhere, but it is especially common when it comes to digital devices. An excessive amount of time spent staring at a screen can lead to eye health issues. These include: headaches, fatigue, dry eyes, eye strain and blurry vision.
Moreover, founder Dhruvin Patel emphasised in their Dragon’s Den pitch that using your electronic devices late at night can actually suppress one of your hormones: melatonin. This is the hormone that signals to your body that it is time to go to sleep; therefore, excessive blue light exposure prior to bedtime can cause difficulties, both with getting to sleep and staying asleep.
How does blue light work?
Blue light can be split into two categories: below 380nm-450nm, and between 470-500nm.
High energy visible light (below 380-450nm
This is the most harmful level of blue light, causing the aforementioned troublesome symptoms.
Blue light within this range is generally considered to be ‘good’. This is due to its use in treatments such as insomnia and seasonal depression.
However, if you are exposed to this level after sunset, this may keep you awake. This is because your body will be convinced that it is daytime due to the light levels present.
How can I protect my eyes from blue light?
According to the Royal College of Optometrists, there are many ways in which you can protect your eyes whilst using a screen. These include:
Using the 20-20-20 rule
The 20-20-20 rule suggests looking at something 20 feet away for 20 seconds every 20 minutes, to rest your eye muscles.
Make sure to blink regularly, as focusing on a screen may make your eyes dry due to a lack of natural blinking.
Wear appropriate eyewear
It is recommended that you wear specialised glasses that filter out blue light to avoid eye strain.
Make adjustments if needed
Altering your font size and screen height can help you to ease the discomfort that comes with prolonged screen use. Changes such as tilting your screen away from you at a 10-20 degree angle can make a huge difference in terms of avoiding eye strain.
You can find out more about adjusting your screen, as well as other eye health tips on their website.

Why is Ocushield important for Optometry?
As Tej Lalvani mentioned within his offer, it is a lesser-known fact that healthcare and technology often go hand in hand. Within any healthcare field, the patients are of the highest priority; Patel himself cites the main goal of Ocushield as, “enabling people to live a healthier life with the increasing amount of digital technology.”
The international expansion of this UK-based healthcare business will allow optometrists to help their patients across all aspects of their life, working with, and not against, technology.
