One of the key points of sun protection is wearing sunglasses. Sunglasses not only make you look good, they protect your eyes from the sun’s harmful ultraviolet (UV) rays, prevent your eyes from straining in bright conditions and protect your eyes from bugs and flying debris.

But how do you choose sunglasses to suit your lifestyle? Healthcare Global is here to help. 

What is UV protection?

UV rays can cause all sorts of problems for the eyes including cataracts, cancer and eye disease. The advice is that you should buy sunglasses that block 99-100 percent of all UV rays. These will be labelled as having 100 percent UV protection or alternatively a UV 400 protection measurement. 

There is also a measurement called Visible Light Transmission (VLT) which determines how much light filters through the lenses to your eyes. Measure as a percentage, VLT is affected by the thickness and colour tint of lenses.

Driving and everyday use

For everyday use, style is bound to be a key factor when deciding on a pair of sunglasses and Ray-Ban is the ultimate cool brand as their styles are old-school at the same time as being a modern label must-have.

Polarised lenses are available on the classic Aviator and Wayfarer frames and are ideal for driving in sunny conditions as they eliminate the glare from the road surface, other cars and surrounding buildings. Ray-Ban’s ‘Natural Grey’ lenses have been dubbed as the ‘natural vision lens’, reducing eye strain and squinting but transmitting colours with no distortion.  

Ray-Ban is also leading the way in innovations with Carbon Fibre and CL (Carbon Light) ranges to offer the ultimate in strength and comfort. The lenses in these glasses are good too; polarised with high colour definitions, anti-reflective treatments and glare elimination techniques protects the eyes 100 percent from all UV rays. 


Skiing is one of the most harmful activities for the eyes. Snow is highly reflective and generally speaking UV intensity increases by four percent at every 1000 feet above sea level. Snow blindness is the main concern when in high-altitude areas; a very painful, usually temporary blindness caused by exposure to UV rays reflected from snow. For these conditions you need sunglasses that have five-10 percent VLT and have a UV 400 protection. In terms of the shape of the sunglasses – the whole of your eyes should be covered and the frame should ‘wrap’ around your face.

Why not try the Adidas Evil Eye Explorer sunglasses? Each pair comes with two interchangeable lenses and there are a number of different frame and lens options. The ‘space’ lens is the most appropriate for skiing as it offers protection against extreme radiation and glare. Each lens is polycarbonate to offer strength and has anti-fog technology. The glasses also come with a detachable head strap so they can double up as goggles.

On water

Glare and reflections from water is also harmful to your eyes and polarised lenses are probably the best for reducing eye fatigue as they block the light that is reflected from the surface. Polarisation also enhances clarity and enables you to see below the surface of the water; ideal for fishing and surfing.

Oakley has a number of sunglasses that are suitable for wearing in or near large expanses of water. The Oakley Radar frames are ideal for active water sports because of their Hydrophobic lens coating which prevents water from leaving streaks or smears and impairing vision.

Meanwhile, the Oakley Straight Jacket frames were created specifically for anglers. The Straight Jacket lenses provide you with clear and unobstructed vision at the same time as filtering out 100 percent of harmful invisible UV rays.


High altitude mountaineering or desert trekking requires glacial sunglasses that will protect against harsh, intensive sunlight and reflective glare. Only lenses with a dark or very dark tint are suitable to use in these conditions.

The climate in mountainous areas can change rapidly, so photochromatic lenses which adjust to changing light conditions are good for trekking. Anti-fog coatings and polarised lenses are also useful features in glacial sunglasses.

Julbo is one of the leading glacial sunglass brands. The Explorer frame is Julbo’s top of the line mountaineering sunglasses. The photochromatic, antifog, polarised Camel lenses protect from high-altitude sunlight and its UV rays.  

The removable side shields from Julbo’s MonteBianco frames mean they can be used for everyday wear as well as trekking. These are available with either a Spectron 4 lens (recommended for water, bright sun and altitude conditions) or the Camel lenses of the Explorer.

How healthcare can safeguard itself against cyberthreats

Jonathan Miles, Head of Strategic Intelligence and Security Research at Mimecast, tells us how the healthcare sector can protect itself from attacks

One of the most fundamental lessons from the COVID crisis is that health should always be a priority.  In a similar fashion to the human body that frequently fights off viruses and foreign invaders that intend to cause it harm, the sector itself is now a prime target for another type of external threat: cyberattacks.

The figures speak for themselves: between December and January this year, hospitals in the UK were at 89% capacity, with 7,000 fewer available beds than there usually are. As the pandemic increased pressure on hospitals, clinics, and research facilities to create a treatment for patients globally, it has left the sector exposed to hackers who, like a virus, have been targeting it relentlessly and evolving their tactics. 

From patient records being held ransom, to fake emails claiming to originate from the UN WHO, the NHS, or vaccine centres, through to attacks on the cold supply chain to find out the secret formula of the COVID vaccine, the healthcare industry is facing constant cyberattacks and struggling to cope. This threat is unlikely to go away anytime soon – and as such, the industry needs to take a proactive, preventative stance to stay safe in a dynamic digital world. 

Going digital 

The responsive nature of healthcare – particularly of hospitals – means that efficiency is crucial to the industry’s standard operations. To support this, the sector has been embracing technological advancements that can improve the quality of work, enabling staff to meet pressing deadlines, and enhancing patient care. For example, the industry has been digitising records and improving its ways of working through digital means over the past few years. 

This shift is critical to offer high quality patient care; yet, it also means the sector has become more dependent on IT, which can come with a risk if cybersecurity processes employed are deemed as inadequate. 

Without the correct security measures in place, the desired efficiency gains realised, can be easily lost in a heartbeat. Simply put, an elementary glitch in the system can have a tremendous ripple effect on many areas, from accessing patient records and conducting scans, to maintaining physical security and protecting the intellectual property of experimental treatment development.

To prevent this, healthcare organisations need to ensure they’re considering cybersecurity as part of their overall digital transformation strategy – and setting the right foundations to create a culture where safety goes hand in hand with patient care. 

Strengthening defences

Before implementing cybersecurity process, healthcare organisations need to assess the potential risks they face. Depending on how much confidential data the trust has, where it is stored, who has access to it and via which means, the cybersecurity strategy and associated solutions will change. 

It’s fair to say that a medical device start-up where all employees have a corporate-sanctioned laptop and access data via a VPN will have radically different needs to a large hospital with hundreds of frontline workers connecting to the hospital’s Wi-Fi using their personal device. 

These requirements will pale by comparison to a global pharmaceutical giant with offices in multiple locations, a large R&D department researching new treatments for complex diseases and a fully integrated supply chain. Considering the existing setup and what the organisations is looking to achieve with its digital transformation strategy will therefore have an immediate impact on the cybersecurity strategy.

Despite this, there are fundamentals that any organisation should implement: 
Review and test your back-up policy to ensure it is thorough and sufficient – By checking that the organisation’s back-up is running smoothly, IT teams can limit any risks of disruption in the midst of an incident and of losing data permanently.

In our recent State of Email Security report, we found that six out of ten organisations have been victims of ransomware in 2020. As a result, afflicted organisations have lost an average of six days to downtime. One third of organisations even admitted that they failed to get their data back, despite paying the ransom. In the healthcare industry, this could mean losing valuable patient records or data related to new treatments – two areas the sector cannot afford to be cavalier about.

Conduct due diligence across the organisation’s supply chain – Healthcare organisations should review their ways of working with partners, providers and regulatory institutions they work with in order to prevent any weak link in their cybersecurity chain. Without this due diligence, organisations leave themselves exposed to the risks of third party-led incidents. 

Roll out mandatory cybersecurity awareness training - Healthcare organisations shouldn’t neglect the training and awareness of their entire staff – including frontline workers who may not access the corporate network on a regular basis. According to our State of Email Security report, only one fifth of organisations carry out ongoing cyber awareness training.

This suggests it is not widely considered as a fundamental part of most organisations cyber-resilience strategy, despite the fact many employees rely on their organisation’s corporate network to work. By providing systematic training, healthcare organisations can help workers at all levels better understand the current cyberthreats they face, how they could impact their organisation, the role they play in defending the networks, and develop consistent, good cybersecurity hygiene habits to limit the risks of incidents. 
Consider a degree of separation – Information and Operational Technology (IT and OT) networks should be separated.

Although mutually supported and reliance on each other, employees shouldn’t be accessing one via the other. This should be complemented by a considered tried and tested contingency and resiliency plan that allows crucial services to function unabated should there be a compromise. Similarly, admin terminals should not have internet access to afford a degree of hardening and protection for these critical accounts.

As the sector becomes a common target for fraudulent and malicious activity, putting cybersecurity at the core of the organisation’s operations is critical. It will help limit the risks of disruption due to cyberattacks, reduce time spent by the cybersecurity team to resolve easily avoidable errors, and ensure that institutions can deliver patient care, safe in the knowledge that their networks are safe.  

Fighting future threats

With technology continuing to change the face of healthcare, the surface area and vectors available for attacks by malicious actors is constantly increasing. With the introduction of apps, networked monitoring devices, and a need for communication, the attack vector is ever expanding, a trend that needs to be monitored and secured against.

To prevent any damage to patients, staff, or the organisation they are responsible for, healthcare leaders must put security front and centre of their digital transformation strategy. Only then can the sector harness the full benefits of technology. Doing this should include implementing cybersecurity awareness training to challenge misconceptions around security, encourage conversation, and to ensure employee knowledge of the security basics and threats faced. 

This ultimately allows healthcare organisations to do what they do best: provide the highest standard of patient care, safe in the knowledge that their operations, patients, and data are safe.
