Taking a dip while wearing contact lenses may seem harmless. But it isn't at all. Doing so can result in irritation, eye infections and potentially sight-threatening conditions such as corneal ulcer. In fact, you shouldn't even take a shower with them on. "Contact lenses shouldn't be exposed to any kind of water, including tap water and water in swimming pools, hot tubs, oceans and lakes. Lakes and rivers are most likely to host bacteria, but swimming pools and even tap water can harbour dangerous microbes including the Acanthamoeba organism, which causes a painful corneal infection that is difficult to treat and can cause permanent vision loss," says Dr Leo Seo Wei, a senior consultant ophthalmologist at Mount Elizabeth Hospital. She adds that the chemicals in swimming pools are more likely to irritate your eyes if you're wearing contacts because they're porous and absorb chemicals. Plus, water can wash away the eyes' natural tear film, making them drier. CAN I AT LEAST SLEEP WITH … [Read more...] about Ask a doctor: Can contact lenses get lost in my eyes?

Watch more in iWant or TFC.tv Vic Herrera has been fishing in Pasig River since the late 1970s. He knows the ebb and flow of the once biologically dead river, which he said “dies” or becomes foul-smelling during summers. In the months that it is alive and infused by rainwater and the Laguna Lake, the 58-year-old vendor brings out his fishing rod in search of tilapia. “Malinis pa ito (noong 1977),” Herrera says. “Biya, talangka, hipon at saka gurami. Maraming isda dito nu’ng ’70s. Mababaw ’yan, kita mo pa ang buhangin d’yan. May mga tulya dito noong araw.” (It used to be clean in 1977. There were gobies, crabs, shrimp and gourami. There were a lot of fish here in the ’70s. The river was still shallow and you could see the sandy bottom. There were also clams.) In the 1990s, Pasig River was declared biologically dead because of extreme water pollution that made it impossible for living organisms to thrive in. Herrera points … [Read more...] about ‘Monster fish’ in polluted Pasig River explained
In April 2018, the Sangguniang Bayan of the small town of Majayjay in Laguna took action against indiscriminate dumping of waste into its rivers. This formed part of its moves to help agencies comply with the Supreme Court’s order in 2008 to continue cleaning up Manila Bay and restoring its waters to Class SB level, or those used for public bathing and swimming or fish spawning. After all, human and hog waste released into practically all of Majayjay’s water bodies find their way into Manila Bay, although in dissolved and diluted forms, depending on weather and water conditions. Save for Maimpis River, the Olla, Oobi, and Botocan rivers and the Initian Creek are all linked to Balanac River, which flows into Pagsanjan-Lumban River, which in turn is connected to Laguna de Bay. The Philippines' largest freshwater lake meanwhile flows out into the Pasig River, one of the tributaries of Manila Bay. Recognizing that the town’s waste goes … [Read more...] about Majayjay mounts slow, failing battle vs. sludge from hog farms
