GLARE, NO MORE!

Nature is congregated with many miracles, waiting for us to discover them. These miracles have led to technological advancements, which have aided humans significantly, for a long time now. This progress has made a powerful impact on our lifestyles, promising us for a better future, and at the same time trying to make every minor thing better.

One such research promulgated that a moth’s eye is made up of such nanoparticles which have anti-reflective property. Antireflective property suggests that a surface has high absorptive power due to its configuration and reflects back less light. Antireflective materials (also referred to as antiglare or AR coating) are used in eye lenses, for better visibility and less strain.

It is surprising enough that such a complex material is also found in such a small being! Moths are basically nocturnal creatures, and therefore require better visibility during night. This coating helps them locate insects at night and avoid predators. A typical moth eye consists of extremely tiny protuberances called corneal nipples, arranged in a well-defined hexagonal pattern, allowing low reflectivity. This discovery has inspired scientists to use such a coating on electronic devices to reduce glare. The moth-eye structure can be bio-mimicked and applied to solar cells, cell phones, monitors, etc.

One of the best pertinence of this new technology would be its use in mobile phone screens. It will benefit each one of us as we will be able to see our screens clearly even in bright daylight, without the need of finding shade here and there. A very famous American physicist, and a professor at the University of Central Florida, Shin-Tson Wu estimated that such an antiglare screen can improve readability by the user up to 10 times in sunlight.

Apart from providing better readability, this screen is scratch-resistant and self-cleaning. Also, this film will turn out to be inexpensive for all its users as soon as it comes to the market. This screen can also be tested in laptops. It will give users an option to operate laptops at dim light, thus saving battery and energy. Similarly, trying this in televisions and monitor will reduce strain on the eyes of the user.  This can also be experimented with solar panels, it will boost efficiency in gaining power.

 

Therefore, nature has options to solve every problem and to fulfill every need of the humans. We just need to be a little more critical, curious and alert to our surroundings. Who knows, we might end up discovering something fantastic for the mankind.
