Ever spent more than two consecutive hours looking at a computer screen? Us too. Computers can make us more productive, but the bad news is that too much screen time can also lead to something called computer vision syndrome(CVS). Recognizable as that tired, strained feeling your eyes get after a day in front of a computer screen, CVS affects some 64% to 90% of office workers.

Ever spent more than two consecutive hours looking at a computer screen? Us too. Computers can make us more productive, but the bad news is that too much screen time can also lead to something called computer vision syndrome (CVS). Recognizable as that tired, strained feeling your eyes get after a day in front of a computer screen, CVS affects some 64% to 90% of office workers.

The condition likely doesn’t cause permanent eye damage, but it can still affect computer users’ comfort. The most common symptoms of CVS include eye strain, redness, irritation or dryness, a burning feeling in the eyes, blurred or double vision after computer use, headaches and neck and shoulder pain.

Several factors increase the likelihood of CVS, including uncorrected vision problems, dry eyes, glares on the screen, poor lighting, poor posture and even the angle of the monitor. Another big factor is incorrect prescriptions: almost 71% of people reporting symptoms of CVS wear eyeglasses or contact lenses.

If computer screens are proving a pain in your eyes, here are some guidelines to help ease symptoms:

Have your eyes checked regularly. If you need a new or changed prescription but don’t have it, using a computer will be difficult, period.

Reposition the computer. The screen should be about an arm’s length away and positioned directly in front of your face, not off to the side. Position the monitor so its center is 4 to 8 in. below your eyes, which allows the neck to relax while you read and type.

Follow guidelines for good posture. It’ll reduce strain on the back, neck and shoulders.

Ensure proper lighting. Try the visor test to determine if current lighting is a problem: look at the monitor and cup your hands over your eyes like a baseball cap. If your eyes immediately feel better, then the lighting should be changed. Experiment with brighter and dimmer lighting, as well as the angle of the lights, to find what’s most comfortable for your eyes.

Reduce glare. Installing anti-glare filters on the monitor, adjusting window shades and changing the screen’s contrast and brightness can help reduce glare and reflections.

Blink frequently. It should prevent dry eyes. If that doesn’t work, consider using lubricating eye drops. Also make sure air vents aren’t blowing on your face (this can dry out the eyes), and use a humidifier if the room is super dry.

Take regular work breaks. Stand, stretch or just look off into the distance, away from the computer, every 15 minutes or so to give the eyes a break.

Clean the monitor regularly. Dust can decrease screen sharpness, making the eyes work harder.

Try computer glasses. Unlike everyday eye wear, they’re designed specifically for looking at computer screens.

Consider optometric vision therapy. Some computer users have issues with eye focusing or coordination that aren’t corrected by glasses or contacts. Vision therapy consists of doctor-prescribed activities designed to improve visual functioning (think of it as a workout for the eyes — though no guarantees as to calorie burn).

HealthPlus is experiencing a power struggle 2 years after obtaining $18 m from Alta Semper Capital

A press release apparently released on September 25 by the Board of HealthPlus, one of the largest integrated pharmacy chains in West Africa, confirmed that the company no longer needed the services of its founder, Bukky George, as CEO.

The decision to terminate the appointment of George came with the announcement of Chidi Okoro, the interim leader.

Okoro, a renowned pharmacist and management executive, is to take on the position of Chief Officer of Transformation. Okoro, akin to the position of a CEO, can simplify day-to-day management, help the company scale, and achieve profitability.

And a letter that appears to be from the board of HealthPlus to the Pharmacists Council of Nigeria (PCN) states that George “remains a shareholder of the company, a member of the board of the company, and may engage at board level in the company’s decision-making process.”

Afsane Jetha and Zachary Fond, Managing Partner & CEO, and Director of Alta Semper Capital, respectively, have signed it off.

From investment and partnership to a fight for power

Alta Semper Capital LLP is a private equity (PE) company that invests in Africa-wide healthcare and consumer businesses. In 2017, the PE company invested in Macro Pharma, a medicated cosmetics company in Egypt.

It made deals with HealthPlus and the Moroccan oncology and radiology clinic, Oncologie et Radiologie du Maroc (ODM), the following year.

The HealthPlus investment was $18 million.

HealthPlus, founded by George in 1999, has expanded to more than 90 retail outlets, employing over 850 employees, including more than 150 pharmacists. In Nigeria, the company claims to be present in 11 of the 36 states in the world.

Operating branches in strategically placed suburban areas, airports, and shopping malls are also recognized.

Alta Semper Capital ‘s investment was to help HealthPlus grow its store footprint. In addition, to attract more talent, grow fulfillment centers and pursue initiatives in eCommerce.

The cash inflow, however, is said to have given the PE firm a majority stake in the company, which is one of the reasons why the company is facing problems at the moment.

Coronavirus: The Covid Tracker software from Ireland is out

Ireland’s just-released contact-tracing app this morning, where it joined Germany’s Corona Warn-App, which was released three weeks ago.

Gibraltar recently released its Beat Covid Gibraltar app, based on the Irish code.

The Republic’s Covid Tracker software is also the foundation of an app. Northern Ireland is promising to release within weeks. And now there’s a hint Wales could go the same way.

The focus henceforth would be on building a “decentralised” app with the toolkit offered by Apple and Google, which is also being used by Germany and Ireland among a growing list of others.

On Monday, Baroness Harding gave evidence to the House of Lords Science and Technology Committee alongside Simon Thompson, the Ocado executive she drafted in to take responsibility for the app.

Mr Thompson started by saying how urgent it was to get the job done. He went on to stress that collaboration with other countries and with Google and Apple meant that “we have growing confidence that we will have a product that will be good, so that the citizens can trust it in terms of its basic functionality”.

Bluetooth doubts

Now it is true that there is very little evidence that Bluetooth-based apps have so far been successful in tracking down people who came close to someone diagnosed with the virus.

People who point to the success of countries like South Korea ignore the fact that its efforts have been based not on Bluetooth but on the use of mass surveillance data, which would almost certainly prove unacceptable here.

Scientists at Trinity College in Dublin who advised the Irish app development team have produced a number of studies showing Bluetooth can be a very unreliable way to log contacts.

After tests on a bus they warned “the signal strength can be higher between phones that are far apart than phones close together, making reliable proximity detection based on signal strength hard or perhaps even impossible”.

‘Good enough’

Germany has celebrated the fact that in three weeks its app has been downloaded by 15 million people out of a population of 83 million. But there is little or no information about whether it is performing well in its core mission of contact tracing.

Then again, countries like Germany, Ireland and Switzerland have taken the view that an app does not have to be technically perfect, and that if there is any chance of it making even a small contribution to the battle against the virus, it’s worth a go.

Countries like Germany might be tempted to point out that they have had that “cake” in the form of an effective manual tracing programme all along. Incidentally, if public trust is vital to the app’s rollout, the people of the Isle of Wight may have something to say about that.

Following the trial of the original, scrapped NHSX app on the island, some residents have been asking what will happen to their data. We’ve asked too – and have yet to receive an answer.

While the Covid Tracker app has been launched by the Health Service Executive (HSE) in the Republic of Ireland, people living across the border in Northern Ireland are able to download it and use it.

Its terms and conditions state that it is intended to be used by anyone living in or visiting the island of Ireland.

They also state that its availability for people living or visiting in Northern Ireland “is intended to help us to inform people living in border areas and to trace cases in those areas”.

Anyone using the app in NI is able to activate the contact tracing facility and can also self-report symptoms using the “Covid Check-In section”.

However, in the section which asks users to enter personal details, including gender and age-range, those living in Northern Ireland can’t add their county of residence. Only counties in the Republic of Ireland are listed – not the six in NI.

It isn’t yet clear what impact this has on the functionality of the app for NI users.
