Have you ever faced eye redness? Or have witnessed blurry or foggy vision? Or experiencing halos around lights? Or nausea and vomiting are very common for you. You may well be suffering from Glaucoma which needs immediate attention.
Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.

Glaucoma is a condition that damages the nerve of the eye. The increased pressure in the eye, which is known as intraocular pressure, can damage the optic nerve which is responsible for sending images to the brain. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years. According to WHO, there are different kinds of glaucoma, though, the two most common are, primary open-angle glaucoma (POAG), having a slow and slow and asymptomatic onset, and angle-closure glaucoma (ACG), which is less common, yet more acute. Hence, it is important for everybody over the age of 40 years to have a regular eye check-up.
The eye disorder may be treated with the help of eye drops prescribed by Ophthalmologist. There are various options available to lower intraocular pressure to the desired level. Depending upon the need of the patient, doctor may recommend combinations of eye drops, but it is of utmost importance to use the drops on a regular basis. However, consulting a specialist should be the first priority if diagnosed with glaucoma, but most of the population will first opt for home remedies then will consult chemists' shops for medicines and if the issue is still not resolved then will they think of a specialist. There is a need to modify the mindset of the people and when it comes to sensory organs zero negligence rule should be followed.

Awareness is the key to managing Glaucoma better. The need of the hour is to include eye care as part of the health check-up. Timely detection of Glaucoma will lead to proper medication and diagnosis by an Ophthalmologist. Talking about prevention, early detection will help in managing glaucoma before significant damage occurs. Glaucoma can be because of genetics as well hence knowing the family's eye history is important. Regular and moderate exercise may help prevent glaucoma by reducing eye pressure also eye drops can significantly reduce the risk that high pressure will progress to glaucoma.
Also, there are few home remedies that anyone can follow to avoid glaucoma. Consuming healthy food, using eyewear, avoiding head-down position, keeping oral hygienic, and protecting eyes from sunlight are a few of such remedies. One should be mindful of the fact that Glaucoma is irreversible blindness and awareness can help us in fighting it. Depending on the condition an Ophthalmologist may prescribe an oral medication or may suggest therapies. In severe conditions, doctors can also recommend surgeries like Laser therapy, Filtering surgery, Drainage tubes, minimally invasive glaucoma surgery (MIGS). (IANS/ MBI)

Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a new study. The study, published in the journal Scientific Reports, found there was, on average, a 17 per cent improvement in participants' colour contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week.
However, when the same test was conducted in the afternoon, no improvement was seen. "We demonstrate that one single exposure to long wave deep red light in the morning can significantly improve declining vision, which is a major health and wellbeing issue, affecting millions of people globally," said lead author, Glen Jeffery from the University College London.

For the study, the team involved a small yet significant number of participants aged between 34 and 70, had no ocular disease, completed a questionnaire regarding eye health prior to testing, and had normal colour vision (cone function). This was assessed using a 'Chroma Test' -- identifying coloured letters that had very low contrast and appeared increasingly blurred, a process called colour contrast.
Using a provided LED device, all participants were exposed to three minutes of 670nm deep red light in the morning between 8 a.m. and 9 a.m. Their colour vision was then tested again three hours post exposure and 10 of the participants were also tested one week post exposure. On average there was a 'significant' 17 per cent improvement in colour vision, which lasted a week in tested participants; in some older participants, there was a 20 per cent improvement, also lasting a week.
A few months on from the first test (ensuring any positive effects of the deep red light had been 'washed out') few participants, carried out the same test in the afternoon, between 12 p.m. to 1 p.m. When participants then had their colour vision tested again, it showed zero improvement.

Our eyes play an important role in our lives. They are the sensors that relay information about the environment to our brain. Eyes alert the brain to the prospect of both a safe environment and lurking danger. Our eyes work all the time - from getting out of bed in the morning to sleeping at night. In modern lives, we have another source of strain on our eyes - mobile phones, laptops and TVs. Studies have shown that unabated exposure to light emitted by these gadgets are harmful for our eyes.
Why eyesight could take a hit?
Technically, our eyesight can take a beating from refractive errors, the normal aging phenomenon (presbyopia, where individuals at 40+ years face difficulty in reading the small print on medicine bottles, and packet contents, among others), eye problems/diseases/infections, and injuries. Natural light is very important for our eyes to remain healthy. In children, a lack of time outdoors could increase their chances of developing short-sightedness. If you notice your eyesight is deteriorating, the most important thing to do is to immediately visit your eye care practitioner for an eye examination / eye test. The practitioner will be able to identify underlying issues that are causing the eyesight to go bad.
Ananthalakshmi. N, Head-Education & Professional Services, Essilor India lists out ways to help keep eyes healthy:
• Eat right - Eat a healthy and balanced diet rich in Vitamin A
• Harmful Lights - Prevent your eyes from harmful radiations / light, especially ultra violet radiations & harmful blue lights
• Sun & the eyes - Sun is the biggest natural source of UV and Light. A healthy amount of sunrays are good for the eyes, looking at the sun directly can cause damage ? even lasting damage ? to the eyes.
• Artificial sources - Today, we all are exposed to a number of artificial sources of light, including LED/ LCD used in artificial lighting (bulbs / tube lights); displays on TVs, mobiles, laptops, desktops, etc. Though not as powerful as the sun, prolonged exposure / proximity to the eyes / angle of exposure, can cumulatively, have a negative impact on the eyes and its well-being.

• To protect Eyes from Harmful lights, radiation, glare and to maintain good eye health, the use of good quality Polarised lenses/ Photochromic (Light Management lenses) / Blue Filters are recommended
• Digital hygiene - 20-20-20 rule ? The 20/20/20 rule says that after every 20 minutes of use, one should look 20 feet away for 20 seconds. This will relax the eye muscles.
• Quit smoking - The development of age-related macular degeneration (AMD) and cataract has been linked to smoking. Smoking doubles the chances of losing your sight and can exacerbate diabetes-related vision problems.
• Yearly eye check-ups - Children should be made to undergo an eye check-up before they start school, and thereafter, every year. The most important step you can take to keep your eyes healthy is to undertake regular eye check-ups. An eye test does more than just determine whether you need glasses or a stronger prescription. Your eye care practitioner will also examine the overall health of your eyes, which means he/she will be able to detect early stages of eye diseases, such as cataract or glaucoma, even before you notice any symptoms.

• Wear good quality spectacle lenses - Remember, prescription power only gives the quantity of vision, but the quality of vision is enhanced by choosing a trusted brand of spectacle lens.
Now is the opportunity to develop good eye habits. Taking care of your eyes now, regardless of your age or medical history, can help you avoid vision-related difficulties later in life. If you're in your 20s or 30s, you probably don't give your eye health much thought. It's time to change that perception any give eye-health its due importance.

The COVID-19 pandemic has brought in its wake a burgeoning epidemic of digital eye strain. Digital eye strain can affect anyone with prolonged exposure to screens like smartphones, computers, TV, tablets and video games. Increased screen time has always been a cause for concern among parents and this worry has been intensified of late due to online schooling. Although parents were relieved that classes could continue online, their relief was short-lived as children started to complain of headaches, eye pain and discomfort due to increased screen time. Apart from the usage of devices for online classes, homework and assignments, children increasingly have no choice but to turn to the online platform for socialising with friends and entertainment. This results in screen time of more than 7-8 hours every day and its consequence-digital eye strain.
The commonly reported symptoms among children who suffer from digital eye strain are eye fatigue, eye discomfort, headaches, dry eyes, blurred vision and watering. Prolonged near work and reduced time spent outdoors has also resulted in the new onset of myopia (short-sightedness) and faster progression of myopia in young children.
With schools opting to adopt a hybrid model for the safety of children, prolonged screen time will continue to affect the eye health of students. Therefore, to minimise the adverse effects of increased screen time, it is important to take measures to manage eye strain at home.
As a first step, evaluate your child's virtual study environment and make adjustments if needed.
1. Distance between the eyes and the screen: Make sure the computer screen is about 1.5 to 2 feet or an arm's length away from where your child is seated. Adjust the device so that the top of the screen is at or slightly below eye level. This will ensure that your child is not tilting his/her neck to view the screen.
2. Adjust the light of the surroundings: The room should be well lit. There should not be too much difference between screen brightness and room lighting. Advise your child to avoid using electronic gadgets in the dark. Ensure there is no glare from the screen due to the reflection of light from a window or a light source in the room.
3. Adjust screen brightness: Parents should ensure that the brightness of the screen is optimal (not lighter or darker than the surroundings) and increase the contrast for better viewing. This will also avoid unnecessary strain.

4. Increase font size: Instead of straining to focus when the font size or the object is not visible, it is advisable to zoom the page and read.
5. Use colour settings: The blue light emitted by the screen can hamper your child's sleep especially when the device is used close to bedtime. Decreasing evening screen time and setting devices to night mode may help prevent sleep disruption.
6. Bigger screens are better-: For online classes, use laptops or desktops instead of smartphones as much as possible. For entertainment, watching on a TV screen or casting from the smartphone onto the TV is a better option to prevent eye strain.
Practising good eye habits and eye exercises can also prevent eye strain.
1. Do not look at the screen continuously; Follow the 20-20-20 rule: Our eye muscles relax when we look at objects far away and work hard to focus at a near distance when we are continuously working on a screen. So, reminding your child to take a 20-second break every 20 minutes while using screens will help. They can close their eyes for 20 seconds or look outside their window for a distance of 20 feet or more. Short frequent breaks will help prevent eye strain.
2. Remember to blink while using devices: Blinking keeps the eye surface lubricated with tears. However, we tend to blink less than half as often while using screens. This can make eyes feel dry, heavy, tired, itchy or irritated. Consciously remembering to blink can prevent dryness and eye irritation. Lubricating eye drops can provide relief and can be used when needed as advised by your eye doctor.

3. Ensure off-screen activity: Spend time away from the screen after online classes to give enough rest to the eyes. Engage kids in activities like gardening, cycling, indoor games etc.
4. Regular eye checks are a must to detect if there is an eye number and need for glasses. Wearing the correct prescription glasses helps in preventing eye strain.
Though it is recommended to avoid prolonged exposure of eyes to screens, however, when it becomes unavoidable the next best thing is to fix the surroundings and make smart use of your devices to minimize the stress and ill effects of screen time. Following the above steps may help to minimise eye strain in children while using screens. Healthy diet, hydration and getting adequate rest are a must to ensure overall good health including eye health.
