If you have two distinct prescriptions, bifocal glasses are worth acquiring since they can fit both in one lens, allowing you to effortlessly transition between the two.

Wearers can, for example, spend the most of their time gazing through the distance component of their lens, then rapidly switch to near-sighted activities like gazing at their phone or a computer screen by staring through the bottom section of their lens. This is more convenient than continually switching between two pairs of glasses.

The bottom half of a bifocal lens, which accommodates near vision, can be designed in a variety of ways. The form of this part of the lens changes based on the demands of the wearer. A half-moon, circle, narrow rectangle, or the whole bottom half of the lens are all possible shapes.

Varifocal lenses combine three prescriptions, generally far vision, intermediate vision, and close vision. Bifocal lenses combine two prescriptions, but varifocal lenses include three prescriptions.

Varifocals, unlike bifocals, easily transition between prescriptions with no discernible line between them. As a result, they appear more like regular spectacles in Bangladesh, whereas bifocal glasses are more noticeable.

It gets more difficult to read or focus on stuff up close as we become older. Presbyopia is a condition that occurs as people become older and is a natural component of the aging process. You may be experiencing presbyopia if you find it difficult to use a phone or read a book up close and must hold objects far away to see them well.

It may be time to acquire bifocal or varifocal spectacles if you currently wear glasses and notice presbyopia. If you don’t currently use glasses, single-vision lenses may be all you need. Our varifocal lenses are accessible to see on the prescription journey, but if you’d like to learn more about our bifocal alternatives, make an appointment with one of the recognized opticians in Bangladesh to discuss your alternatives.

Because podcasting appears to be all the rage these days, it’s no surprise that there is a slew of episodes devoted to the big, vital issue on everyone’s mind: climate change. It’s difficult not to think about it when the world is burning, hurricanes are destroying houses, people are losing their jobs, and, well, you get the picture. But why has podcasting become a popular medium for discussing climate change? Earther spoke with Mary Annase Heglar, one of the co-hosts of the Hot Take podcast, which investigates how the media covers climate change, to get some insight on the subject. Climate change, in Heglar’s opinion, is a large issue that may be discussed in a variety of ways. On the other hand, there are so many ways to communicate about climate one podcast that it might be confusing. And in those circumstances, Heglar says, it’s best to simply hash it out like you’re talking to a buddy, which is a lot simpler to do on a podcast than in writing.

Climate Cash is a three-part audio series produced by the World Wildlife Foundation’s Australian division. Dr. Gilly Llewellyn, the Foundation’s Conservation Director, speaks with public and private sector specialists, local leaders, and government officials on the challenges that pose the greatest to Southeast Asia and the Pacific area. They also talk about what Australia can do to mitigate the harmful effects of climate change. MIT Climate produces a podcast called Climate Conversations. MIT Climate is the central point for all scientific studies on changing climate at the Massachusetts Institute of Technology.

The institution hopes to “connect questions to answers, research to solutions, and knowledge to action” via MIT Climate. Climate Conversations make climate science simple and easy to grasp, especially for science n00bz like myself, if you want to know what’s going on from a scientific standpoint. For news on climate change that is succinct and informative, go to the podcast to listen to is NPR climate change podcast. Episodes range in length from five minutes to over an hour, depending on the day and the guests, so you’ll always have something to listen to, whether you’re cleaning your teeth in the morning or driving to work. Costing the Earth is a BBC podcast about climate change that airs on the other side of the Atlantic. The program focuses on “man’s influence on the environment and how [the ecosystem] reacts,” as they put it. They cover a wide range of issues, from golf courses built on dunes to the impacts of climate change on human and animal reproduction. The thing I like best about Costing the Earth is that they question commonly held climate change “trends.” For example, in the episode “Plasticphobia,” host Tom Heap speaks with specialists on whether plastic is as horrible as popular discourse portrays it to be.
