7 Easy Habits That Will Support Your Eye Health This Summer
Your skin isn't the only part of your body that needs to be protected from the sun's UV rays. The same goes for your eyes, especially during the summer months. The World Health Organization reports that 15 million people worldwide are blind from cataracts, and for up to 10% of these people, the cause of their condition may have been exposure to ultraviolet radiation.
Fortunately, there are simple habits you can adopt that will keep your eyes healthy and happy as the summer sun beams down.
How to protect your eyes from the sun
There are plenty of ways to protect your eyes in the heat, from wearing sunglasses to following a balanced diet. Here are some science-backed tips for summer eye care.
Wear sunglasses
One of the easiest -- and most stylish -- ways to take care of your eyes is by wearing sunglasses during the day. When your eyes aren't protected from the sun, they're exposed to multiple types of UV rays, which can increase your risk of certain diseases, including photokeratitis and cataracts.

Consider polarized lenses: Polarized lenses are designed with a special chemical that filters more light than other sunglasses. They also reduce glare from reflective surfaces, like water and snow, so they're a good option if you spend a lot of time outside.
Choose the right lens color: While it may seem like darker lenses would provide more protection from UV rays, the opposite is true. Extremely dark lenses force your pupils to open wider, allowing more sunlight into your eyes. Instead of dark lenses, opt for gray or smoke-colored lenses to get the most sun protection.
Keep your eyes hydrated
During summer, your eyes can dry out quickly, particularly if you live in a dry climate, sit in air-conditioned spaces regularly or spend lots of time in swimming pools. Dehydrated eyes can have uncomfortable consequences, causing burning, irritation and light sensitivity, which may get worse if you wear contact lenses.
Avoid alcohol: Drinking alcohol can also dry out your eyes, so reducing your booze intake may help keep your eyes more lubricated and stave off dehydration.
Use eye drops if your eyes are dry: If you have a moderate case of dry eyes, you may find some relief from over-the-counter eye drops. But if the irritation continues, talk to your doctor about getting prescription-strength drops.

Eat a balanced diet
Following a nutritious diet can also benefit eye health. Specifically, you'll want to aim for a well-balanced meal plan that includes a variety of antioxidant-rich foods.
For example, vitamin C may help lower your risk of developing cataracts. Good sources of this vitamin include raw bell peppers, oranges and carrots. Similarly, vitamin E protects your eyes from free radicals, which can damage and break down the tissue in your eyes. You can find vitamin E in seeds, nuts and sweet potatoes. Finally, vitamin A also supports proper eye function and is found in foods like leafy greens and orange vegetables.
In contrast, there are also foods that aren't great for your eye health. Sugary drinks and fried foods, for instance, can raise your risk of diabetes and, later, diabetic retinopathy.
Limit screen time
Staring at a laptop or phone screen for too long can irritate your eyes and lead to eye strain. Common symptoms of eye strain include headaches, light sensitivity, itchy eyes and blurred vision.
However, depending on your job, avoiding screen time may not be realistic. However, there are some eye care tactics you can use to limit the effect that digital screens have on your eyes. Notably, the American Optometric Association recommends following the 20-20-20 rule while you're using electronic screens. This means taking a 20-second break from all screens at least once every 20 minutes to look at an object that's 20 feet away.
Other strategies to protect your eyes from digital screens include lowering the brightness on your devices, switching to dark mode and wearing blue-light-blocking glasses, though research is iffy on these glasses for eye health.
JoseAvoid looking directly at the sun
Staring at the sun for too long isn't just uncomfortable -- it can cause serious, and sometimes permanent, damage to your eyes. When the sun's UV rays enter your eyes, they can form free radicals and harm your retinas, potentially causing a condition known as solar or photic retinopathy.
Milder symptoms of solar retinopathy can range from watery eyes to eye discomfort to headache. If your case is more severe, you may experience blurred vision or blind spots. For some people, these effects are irreversible. If you've noticed that your vision has worsened after viewing an eclipse or looking at the sun, make an appointment with your doctor as soon as possible.
Protect your eyes while outside or playing sports
Aside from wearing sunglasses, there are other effective ways to protect your eyes while you're spending time outside.
For example, if you're gardening or hiking, you can wear a wide-brimmed hat or visor to keep your eyes covered. If you're headed to the beach or pool, grab a pair of goggles to protect your eyes from the water, salt and chlorine and ward off swimmers' eye. Similarly, if you're playing sports, make sure to put on protective glasses to lower your risk of eye injury.
No matter what you're doing, you should also wear sunscreen on your face to prevent burns on your eyelids or the sensitive skin around your eyes.
Get quality sleep
If you've ever woken up from a poor night's sleep with dry and itchy eyes, you've experienced how a lack of quality sleep can impact your eye health, and science backs that up. In one study, researchers found a correlation between low-quality sleep and dry eye disease, noting that subpar sleep quality can aggravate the effects of DED.

When you're tired, you're also more likely to rub your eyes, which could lead to eye damage or an infection. Separately, not getting enough sleep has been linked to other irritating but nonserious health issues, including myokymia (eye twitching), bloodshot eyes and puffiness and under-eye bags.

As Trump administration eases EPA regulations, Houston could pay a price
Washington — Since President Trump took office in January, his Environmental Protection Agency has been both slashing and reconsidering dozens of rules designed to fight pollution. The White House is also firing many of the EPA staffers who enforce the rules that remain. This week, CBS News visited a Houston neighborhood that's near an NRG Energy coal-fired power plant, the largest in Texas. When CBS News visited the same neighborhood in December, Mr. Trump had just been elected to a second term, promising the energy industry that he would roll back environmental regulations that protect air quality. "I think of pollution as a silent and invisible killer," Dr. Winston Liaw, chair of the Health Systems and Population Health Sciences Department at the University of Houston, told CBS News. Liaw treats patients who run a higher risk of lung disease, asthma and heart attacks due to emissions from oil refineries, chemical plants and coal plants in the Houston area. He explained how the air in Houston can impact human health. "There are these tiny particles, and they're so small that they bypass a lot of our defenses," Liaw said. "And then they start injuring all sorts of tissue in our body." A 2018 study from Rice University found that pollution from the NRG plant contributes to 177 premature deaths per year. In April, the Trump administration gave 68 plants — including the NRG plant in the Rice study — a two-year exemption from complying with federal regulations intended to lower mercury emissions, a powerful toxin that can affect the brain. CBS News analyzed the Trump administration's exemptions and found that nearly 65% of these plants are located within 3 miles of low-income, minority communities. "Bottom line is, who's more at risk are poor people," said Ben Jealous, executive director of the Sierra Club, an environmental advocacy group that has led an effort to try and close almost two-thirds of the nation's coal plants. "When you start increasing production of coal-fired power plants, you're going to kill more people, and you're going to cause more heart attacks, and you're going to cause more asthma attacks," Jealous said. In a statement provided to CBS News, NRG Energy said its "coal units operate in compliance with the current Mercury Air Toxics Standards (MATS) and will operate in compliance with any future MATS requirements." In a separate statement, the Trump administration said Biden-era coal plant regulations "stacked burdensome regulations on top of the longstanding Mercury and Air Toxics Standards, raising the risk of coal-fired plants shutting down – which would eliminate thousands of jobs, strain our electrical grid, and undermine our national security by leaving America vulnerable to electricity shortages." Jealous argues that coal is not a more reliable energy source than renewable energies. "The argument that coal gives you more reliable energy isn't valid," Jealous said. "Solar, wind and batteries gives you the most reliable, the most resilient grid." More importantly, he said, for the people of Houston and across the country, renewable energy means less pollution.

Human-Centric: A Paradigm-Shifting Prescription For Better Leadership
'A lot of people speak about good leadership,' she said. Then she paused, '…but, I find that not a lot of people actually practice good leadership.' Those words caught my attention. Her pause caught my attention. And, her sincerity caught my attention. Why? The words themselves were quite simple. However, the thing that really grabbed my attention was the fact that I didn't know anything about this woman yet. And, still, she began our conversation by talking about a concept that almost all of us find extremely familiar—connection. Human-Centric Leadership Tiana Homsani Yes, most of us have worked for numerous types of leaders throughout our careers. Some are motivating and inspiring. Others can be soul-crushing and demoralizing. And, then, there some leaders that are, well, unfortunately forgettable. 'Can you explain?' I asked her. 'I'm super curious how you're going to define the concept of practicing good leadership?' 'Good leadership is human-centric,' she added. 'Start with the people, and the results will follow.' That's when my mind was blown—with straight-forward, paradigm-shifting, clarity. These words were spoken by Tiana Homsani, a globally-respected executive who has built a stellar career in the pharmaceutical industry, consumer goods, and beyond. She's built a leadership reputation at iconic companies like Abbot, Roche, Novartis, GE, Michelin, and today she works at Takeda. I personally have been writing, researching, and speaking about leadership my entire career. I've interviewed some of the most respected C-Suite Executives, and Thought-Leaders. I've heard all the theories. I've read all the global studies. But, 'human-centric-first' seemed so straightforward. It was almost too simple. 'To say human-centric-first, is one thing,' she said. 'To do it, is another.' That level of simplicity was brilliance. It's not enough to say 'put people first.' A good leader actually has to live by their own words. And, Tiana Homsani has built a career creating stellar results based on this philosophy. 'I took an obscure path,' Homsani told me. 'Obscure?' I asked. 'I'm looking at your LinkedIn profile as we speak. 'Is consistent climbing obscure?' Homsani continued to fill me in on her career path. She explained how she began her career with a degree in mechanical engineering. Then, she shifted into supply chain. And, as she continued to move forward she adjusted her skills into marketing—building a career managing brands, building teams, and understanding that something bigger than job skills, job function, and possibly even experience, education and intellect was the driving force behind her success. 'Yes, it was an obscure path,' Homsani continued. 'But, it gave me insights into something bigger—the act and practice of leadership.' 'What do you mean by that?' I asked. 'I got to experience good and bad leadership. I was able to work for leaders who were high-performing. I worked fear-based leaders. And, I was able to witness different leadership styles across various industries. Of course, I could say that the best leaders are those who are resilient, adaptable, goal-oriented, and even charismatic. And, all of things are important.' 'But?' I asked, feeling like she was leading me up to the big secret. 'You've got me on the edge of my seat. What's the big secret of great leadership?' Homsani paused. It wasn't a pause that made me think she didn't know the answer. Instead, it was a pause that she was too humble to share. 'It's so simple,' she said, 'but once you witness it, you'll immediately recognize the greatest leaders from your past, and realize how you can become a better leader starting tomorrow.' '…and, you've got my attention,' I blurted. 'What is it?' 'It's connecting with people,' she replied. 'Most leadership frameworks are broken because those frameworks ignore the core driver of performance—connection.' She is right. Consider the leaders in your past who inspired the best from you. They weren't the fear-based leaders. They weren't the numbers-based leaders. They were the leaders who actually connected with you. 'Connect with people,' Homsani repeated. 'Great leadership isn't about knowing more than everyone else. It's about connecting with with everyone else and giving them greater opportunities to become the best version of themself. Looking back on my career, I realized that my best leaders were those who allowed me to give more, to give my all, and they actually connected with me as a human, rather than just an employee.' 'I like that,' I replied. I like that a lot. But, let me ask you a question. When connecting with people, what matters more to employees—the big moments or the small moments,' I asked. 'As leader, connections come in both big and small moments,' she replied. 'However, I think the daily small moments are the most meaningful. And, I can explain that. Often times when I'm leading new people, or a new team, and I'm connecting with them, I can clearly see their skepticism. They're wondering why I'm honestly trying to be so helpful—even with the little things. That's the job of a great leader.' How can you connect with people on your teams? I asked Homsani to provide more paradigm-shifting steps any leader can use. It's obvious after hearing how Tiana Homsani thinks and speaks, why she's become so successful as a leader. Her presence (even to a random interviewer like me) exudes kindness, compassion, and transparency. This left me with one final question. 'Tiana, you must get pushback from other leaders who maybe think your approach is too soft. Have you experienced pushback?' And, that question, triggered the biggest smile during this entire conversation. 'Absolutely!' She replied. 'I once worked with another leader who was totally against my theories. In fact, was adamant that my theories couldn't compete. He told me we'd fail. I told him to hold that thought. I went and retrieved my team's numbers. And, just told him to take a look. Then, I waited for his response.' 'And, what'd he say?' 'His response was simply 'When can we start?'' She shifted his leadership paradigm.
