Digital rules, and most people these days are glued to a screen for several hours a day, slowly eroding away their precious eyesight.

Whether at home, at the office, or even while travelling, it is almost hard to imagine life without mobile screens, computer screens and the television! For corporate professionals, both their professional and social life often involves staring intently at a screen.

For these reasons, a lot of computer users today are developing edigital eye strain’ or ecomputer vision syndrome’ and experience symptoms such as eye strain, headaches, dry eyes and blurred vision, says Dr. Mahmood Husein, MBBS; DOMS; FCPS; MS. HOD Ophthalmic Department, Saifee Hospital.

If you spend a lot of time looking at a screen and have started to experience any of these symptoms, the first thing to do is to reduce your screen time. The doctor, who is also associated with mfine, a virtual hospital on the cloud, shares useful tips to take better care of your eyes:

1. Place the computer screen at least 20 inches away from you

Ideally, the computer screen should be between 20-40 inches away from you. If it is too close or too distant, it may cause you to sit in an awkward position. Also, the top of your computer screen should be at or a little below eye level, to minimise any strain on the eyes.

2. Ensure that the screen is not too bright

When your screen is very bright, you are exposed to more eblue light’. This type of light can harm the eyes and affect your vision. Moreover, if you are sitting too close to a window or you can see reflected light in your computer screen, it can lead to eye strain and fatigue. Instead, ensure that the room is well lit. Reduce the brightness of your screen and add a glare filter if possible. Also, reduce the colour temperature of your display in order to reduce the amount of blue light emitted by the monitor.

3. Use a separate pair of computer glasses if necessary

Some people who do not need glasses for everyday use may benefit from using glasses specifically prescribed for computer use. Others who are nearsighted may find that their current prescription is not ideal for the computer; they could also benefit from special glasses meant for intermediate distances, rather than progressive or bifocal lenses.

4. Take a break and look away from your screen

If your work requires you to look at a computer screen for a long time, make sure you take regular breaks. Follow the 20:20:20 rule to reduce eye strain: every 20 minutes, look at an object about 20 feet away for 20 seconds. If possible, walk away from your desk every hour or two, and look at a distant object through a window. This change in focus helps to exercise and thus relax the muscles of the eye.

5. Keep your eyes refreshed

When you stare at a screen, you tend to blink less, which tires and dries the eyes. This, coupled with the air-conditioning of most corporate offices, may result in the eyes becoming very dry. To avoid this, take a break every couple of hours to splash some cold water on the eyes. Remember to blink more often to keep the eyes lubricated. Cooling drops can also help to refresh the eyes.

If you still experience trouble with your vision despite taking all these precautions, you are encouraged to visit an ophthalmologist at the earliest and get your eyesight checked. (IANS)

We are part of a thriving, young, and vibrant nation. We also belong to a civilization that is timeless in age backed by a culture that has gifted the world spiritual enlightenment, technological progress and unbound and selfless wisdom. At no point in time were we anything but givers to the global community as a whole. Today, as the winds of technology blow, Indian minds are not just powering this revolution but leading it as well.

A nation of our stature also attracts the attention of the wrong kind. In the last few years, we have seen reports of how actors backed by nation-states and non-state actors consistently attacking our critical and non-critical infrastructure for various reasons. These attacks are not limited to the defense sector alone. Healthcare, transport, IT, telecom have each been attacked in the recent past. Such attacks point to the activation of bot farms consisting of millions of zombie devices that have been hacked to serve as a source of processing capacity for launching cyberattacks on India.

Some of these attacks are being carried out with the discipline of a regular army. It carries all the signatures thereof — including high levels of research and reconnaissance, multiple attacks to gain entry, precision targeting, disciplined and patient approach towards creating a beachhead, and, last but not least, persistent attempts to hack and acquire information. Such attacks need to be countered at various levels, and we need to evolve and deploy a cybersecurity doctrine that affords us protection and secures our infrastructure, minds, and resources.

The environment

There is a rapid deterioration of international stability across our immediate neighborhood, the Middle East, Eastern, and Central Europe alone with continuing geopolitical turmoil that is shaping foreign and domestic policy decisions around energy and defence. The challenge for all of us is the character of the competition being fueled by nefarious means is being conducted by authoritarian opponents who are part of nations that have not tasted democracy in its entirety ever. They also have armed forces who have been issued carte blanche by their political masters to indulge in international chicanery that ends at the doorsteps of democracies like ours and harms our growth aspirations.

Our adversaries are not just attacking the foundational pillars of our existence as a nation but also attacking our way of life and our freedoms in a manner that is quite difficult to defeat without undermining those very freedoms we seek to protect. Our adversaries are making a concerted attempt to undermine cohesion, erode economic, political, and social resilience, and challenge our strategic position in our part of the world. Such efforts have to be met with a level of resistance that doesn’t merely defeat these machinations but also serves to deter future attempts.

The increasing digitization of our growth is opening new ways to execute a type of “political warfare” that relies on the use and abuse of information, online espionage, state-backed cyberattacks, and intellectual property theft, among other things. The chain doesn’t stop here. It is often backed by the promotion of misinformation and fake news in cyberspace.

Our response

We need to address this challenge through a strategic response that integrates all levers of power and operations. We need to bring in a renewed coherence and consistency to our defence strategy for the next decade, which will be a critical one as we aim at becoming a $5 trillion economy. We need to be able to strike and protect a dimension that emerges from the integration of five domains that are space, cyber and information, air, maritime, and land. This integration will change the way we fight and the way we develop the capability to protect and defend.

Our armed forces, in the future, will have to develop and deploy a strategy that gives them the ability to operate at a micro and nano levels with a small force while moving faster relying on a very high degree of mobility, electronic warfare and passive deception measures to maintain the information advantage we possess now. More and more automated, supervised, and autonomous platforms will be integrated in a manner to enable the faster introduction of new tech as also the ability to defend or strike hard as required while maintaining a deterrence posture that conveys strength and resilience. Disabling of adversarial infrastructure for the short or long term will be a part of this measure.

Such a high level of modernization will need us to embrace information-centric technologies and approaches. We also need to recognise the need for the application of a blend of technologies such as computing power, connectivity, machine learning, IoT and artificial intelligence [AI],

automation, autonomy, and quantum computing to attain the disruptive power we need.

The path ahead

We need to initiate work on multiple projects in parallel to support the goals I have outlined previously without losing focus. These projects should focus on areas where ethical technologies and a high level of automation can bring a plethora of advantages while we redefine data as a strategic and uncompromisable asset. The industry in India needs to back us on this front.

We must embrace open, outwardly facing innovation across all segments and outsource to strategic partners. No one can do everything anymore, as this leads to erosion of core competencies and dilution of strengths. A high level of collaboration with the academic and entrepreneurial ecosystem is the need of the hour. We must utilise technology scouts to amplify our R&D capabilities and support universities, research centres, startups, and established companies looking to develop strategic alliances with the right partners.
