The booming market for digital devices has flooded us with plenty of options to choose from, for various purposes ranging from entertainment to educational and professional uses. Mobile phones, tablets, laptops and video gaming devices have come to play an important part in our daily lives, however, they have also impacted our lifestyles, resulting in some new types of health issues. One of the most common results of the improper/excessive use of digital devices has been an unpleasant eye condition called ‘digital eye strain’.

What is digital eye strain?

Digital eye strain results from spending long hours on digital devices. Common symptoms include watering, itching, stinging or burning sensation, with tired and achy eyes. Sometimes there may be blurring of vision and headache after intense use of digital devices.

Until recently, this condition was commonly seen among IT professionals. But lately, we see many children as young as 4-5 years old being brought to the Ophthalmologist, with digital eye strain.

What has changed for these children? With the shifting of schools to online learning due to the current pandemic, children now spend longer durations with gadgets. It is important that we teach our children on ways to use digital devices without straining their eyes.

Dos and Don’ts for children while using digital devices for long durations

1. Make sure that they sit in well-lit rooms.

2. The device must have a large screen. Avoid small screens like mobile phones or tablets.

3. The screen should be about 40-50 cm from the eyes with a tilt of 10-20 degree and just below the eye level for comfortable viewing.

4. Encourage them to take a break from the screen every 20 minutes or so, and look at some far off object about 20 feet away for 20 seconds before resuming work on the screen. This is called 20-20-20 rule which gives much needed relief for the muscles of the eyes.

5. Use break times to rest and relax the eye. Avoid using digital devices during breaks.

6. Encourage them to blink more often. The blink rate of eyes comes down to about 3-4 from a normal blink rate of 12-15, as one works on the screen for long periods. This hampers the spreading of tear-film, causing dry patches and discomfort in the eyes.

7. For any online extracurricular activities, it’s a good idea to cast it on television which has a bigger screen and can be viewed from far off distance without strain on the eyes.

8. Avoid screen-related activities about 1-2 hours prior to bedtime.

When to consult a doctor

Following the tips outlined above will go a long way in avoiding digital eye strain, especially in young eyes. In spite of all these precautions, it’s not unusual for the child to complain of redness, watering, itching, blurring, headache and in severe cases, even squinting of eyes.

In any of the aforementioned cases, immediate consultation must be sought from a qualified Specialist Ophthalmologist who will thoroughly evaluate their eyes and give appropriate treatment. It’s not unusual for the ophthalmologist to detect refractive problems or squint in eyes which the child and parents may not be aware of.

The only connect for our children with the outside world in these challenging times is through these digital devices! Let us not chide them for using these devices, but teach them the proper way of utilizing them for their benefit!

Union Finance Minister Nirmala Sitharaman, on Friday, said that the Bharatiya Janata Party (BJP) plans to reintroduce electoral bonds in some capacity following extensive consultations with all stakeholders, should it come back to power in the 2024 general elections, according to a report in the Hindustan Times (HT).

HT cited Nirmala Sitharam as saying, “We still have to do a lot of consultation with stakeholders and see what is it that we have to do to make or bring in a framework which will be acceptable to all, primarily retain the level of transparency and completely remove the possibility of black money entering into this.”

However, the Centre has not yet decided whether to seek a review of the ruling made by the Supreme Court (SC), she said.

She further added, “What the scheme, which has been just thrown out by the Supreme Court, brought in was transparency. What prevailed earlier was just free-for-all.”

Launched in 2018, electoral bonds were accessible for acquisition at any State Bank of India (SBI) branch. Contributions made through this programme by corporations and even foreign entities via Indian subsidiaries received full tax exemption, while the identities of the donors remained confidential, safeguarded by both the bank and the recipient political parties.

On February 15, a five-judge Constitution Bench struck down the scheme, deeming it ‘unconstitutional’ due to its complete anonymisation of contributions to political parties. Additionally, the Bench stated that the articulated objectives of curbing black money or illegal election financing did not warrant disproportionately infringing upon voters’ right to information.

FM Sitharaman said, some aspects of the scheme need improvement and they will be brought back following consultations.

She also lashed out at the Opposition’s claims that the BJP disregarded criminal charges against leaders who switched from other parties to join the ruling party.

The HT quoted her as saying, “The BJP can’t sit here and say, you come to my party today, and the case will be closed tomorrow. The case has to go through the courts that have to take a call; they will not just say, “Oh, he’s come to your party, close the case.” Doesn’t happen that way. So is this washing machine a term they want to use for the courts?”

She further said that the Union government plans to simplify the process of taxation and make it easy for investments to come through into the country.

New Delhi: Seventeen Indians are on board an Israeli-linked container ship that has been seized by the Iranian military amid heightened tensions between Iran and Israel.

Official sources said India is in touch with Iranian authorities through diplomatic channels, both in Tehran and in Delhi, to ensure the welfare and early release of the Indian nationals.

The Iranian action came amid increasing fears that Tehran may launch an attack on Israeli soil in retaliation to a strike on the Iranian consulate in Syria 12 days ago.

"We are aware that a cargo ship 'MSC Aries' has been taken control by Iran. We have learnt that there are 17 Indian nationals onboard," said a source.

"We are in touch with the Iranian authorities through diplomatic channels, both in Tehran and in Delhi, to ensure security, welfare and early release of Indian nationals," it said.

Reports said Iran's Islamic Revolutionary Guards seized MSC Aries on Saturday morning when it was sailing through the Strait of Hormuz.

An Indian-origin woman studying at the prestigious Princeton University in the US is among two students arrested over pro-Palestine protests on the campus, reports student and alumni newspapers.

Tamil Nadu-born Achinthya Sivalingan and Hassan Sayed were arrested after the protesters set up tents for an encampment in a university courtyard early Thursday morning, according to the Princeton Alumni Weekly (PAW).

The two graduate students were arrested on charge of trespassing and have been "immediately barred from the campus", said Jennifer Morrill, a university spokesperson, adding that setting up tents on the campus violated university policy.

However, they have not been evicted and will be allowed into their housing, another varsity spokesperson Michael Hotchkiss confirmed to the Daily Princetonian.

Ms Sivalingam is a student of Masters in Public Affairs in International Development at Princeton while Mr Sayed is a PhD candidate there.

In a statement, Morill said the students were given "repeated warnings from the Department of Public Safety to cease the activity and leave the area" and they now face disciplinary action. After their arrest, the other protesters "voluntarily" packed away their camping gear, she added.

Hotchkiss said the university did not evict anyone on Thursday and that the university allows students barred from campus to stay in their university-owned housing.

The undergraduate students were warned against occupation and encampment exercises in an email Wednesday, according to the Daily Princetonian.

Princeton students, faculty and community members, and even outsiders were part of the demonstration, the PAW cited organizers of the protest as saying. Large, white tents were set up nearby for upcoming reunions and other events.

A student who chose to be identified only as Urvi termed the arrests as "violent", which included the students being zip-tied around their wrists. The university, however, contested this and said the officers did not use any force and the arrests were made without any resistance.

Pro-Palestine protests have rocked the top US universities as thousands of students have hit their campuses to demonstrate against the Gaza deaths due to Israel’s inhuman military operation. 

The protests, which began at Columbia University in New York, have to colleges across the country and saw hundreds of students confronting cops and raising pro-Palestine slogans.
