Impact of using smartphones

Negative impact of using smartphones

Most of us already get to know that at a certain point there will be a stage in our life of where digital devices will be the most popular and important things in human life. Now we already knew that it is true as our routine life will be missed out without connecting ourselves with this kind of latest technologies such as smartphones, laptop, computer, TV, ipad and many more. But do we aware of the negative impact of using smartphones or any other devices without knowing the proper fact and features about it?

Eye strain and digital devices

While our work are mostly rely on this devices everyday, do remember that smartphones, computer, or laptops are all knows as light transmitting devices. To keep your view much clearer and focused, lights do play an important role to make sure you received a sharp and clear clarity image. However, the blue light in particular may be toxic for your eyes.

Scientists from The University of Toledo have discovered that how blue light emitted from your technology has a potential to lead to an eye disease such as macular degeneration —known as one of the leading causes of vision loss in the United States. Macular degeneration occurs due to the result of photoreceptor cell death in the retina. Its not a new thing for us to know that blue light harms our vision by damaging the retinal layer of our eye.

Photoreceptors cells are function to capture visual images and signal them to the brain using an eye molecule named retinal. Blue lights will get triggered by the retinal produced by our eye and it causes various chemical reactions. These reactions produced by the chemical mechanism can be poisonous to our eyes. Thus, when these photoreceptor cells die, there’s no regeneration.

But, do not freak out! There are many ways for us to avoid all these to happen. Protecting yourself may seem as easy as avoiding blue light — but it may not be that straightforward. That is why we need to always set our screen time accordingly. Also be aware of the brightness of your view from screens, your sitting posture and environment reflections.

Eye strain and digital devices

Computer devices, gadgets and all other VDU devices are the main emission of blue light. Based on studies, blue light entering human eyes help in boosting attention, reaction and mood during the day. However, the blue light can cause damage to the retina. Blue light has the shortest wavelength and contains the highest energy in the visible light spectrum, it can cause eyestrain, headaches, and including macular degeneration after long exposure.

Essilor blue capture lens

Essilor Blue UV Capture lens provides a feature of blocking at least 20% of harmful blue-violet light, up to 3 times more protection against harmful blue-violet light than regular prescription lenses.

Harmful blue light

Ordinary blue cut lens usually appear yellowish, giving a less cosmetic feature and lack of natural colour. This is due to cutting blue light leads to a yellow residual tint on lens. According to physics, blue and yellow belongs to complementary colours, when blue light is absorbed, the yellow as the other complementary colours will appeared. In order to remove the yellow tint appearance, Blue UV Capture is added with a colouring agent that neutralize the yellow residual tint for creating a optical clear lens.

Yes. Blue UV Capture provides 100% UV protection as it filters out harmful violet light spectrum this includes UV-rays emits from the hot sun.

2. What is the difference between Blue UV Capture and normal blue filter lens?

Blue UV Capture is the new molecular technology material used to build the lens, is inside the lens, while blue filter is only the coating on the surface of the lens.

3. Why blue light is not 100% filter?

Not all the blue light is harmful. Filtering all the blue lights will affect the natural colour as it lost the blue colour. Blue light is distinguished into blue-violet and blue turquoise. Blue-violet belongs to high energy harmful wavelength  in the light spectrum, which are harmful to the eyes, filtering it and left over the harmless blue turquoise light preserve the natural vision with consists blue colour.

Adakah kanta penapis cahaya biru baik untuk mata?

Kanta penapis cahaya biru adalah pilihan yang baik untuk menyaring sinar biru yang berbahaya. Cahaya biru adalah salah satu cahaya yang dapat dilihat dari spektrum cahaya. Cahaya biru mempunyai frekuensi pendek, sehingga menghasilkan daya hidup yang lebih tinggi. Kajian menunjukkan bahawa, setelah beberapa lama, pengenalan warna biru pada cahaya boleh menyebabkan kerosakan jangka panjang pada mata anda. Cahaya biru mempunyai panjang gelombang antara lebih kurang 380nm dan 500nm; menjadikannya salah satu panjang gelombang tenaga terpendek dan tinggi.

Is blue light glasses good for eye protection

Mata tidak menghalang cahaya biru masuk. Sinar UV disekat oleh kornea dan lensa dari sampai ke bahagian belakang mata (retina). Cahaya biru melalui struktur ini dan boleh sampai di retina.

Cahaya biru boleh meningkatkan bahaya degenerasi makula dan menyumbang kepada ketegangan mata digital. Menjadi terlalu dekat dengan skrin anda tidak bagus. Orang cenderung meregangkan otot mata ketika fokus dekat.

Panjang gelombang pendek, cahaya biru tenaga tinggi menyebar dengan lebih mudah daripada cahaya yang kelihatan lain, ia tidak begitu mudah difokuskan. Semasa anda melihat skrin komputer dan peranti digital lain yang memancarkan sejumlah besar cahaya biru, visual yang tidak fokus ini mengurangkan kontras dan boleh menyumbang kepada ketegangan mata digital.

Penyelidikan telah menunjukkan bahawa lensa yang menyekat cahaya biru dengan panjang gelombang kurang dari 450 nm (cahaya biru-ungu) meningkatkan kontras dengan ketara. Oleh itu, cermin mata komputer dengan lensa berwarna kuning dapat meningkatkan keselesaan ketika melihat peranti digital untuk jangka masa yang panjang.

Waktu skrin yang panjang menyebabkan hilangnya corak rehat, kerana cahaya biru mempengaruhi tahap melatonin – hormon berehat dalam badan kita. Cahaya berkurang sekitar waktu petang, menghentikan badan untuk membuat hormon rehat seperti melatonin. Cahaya biru menimbulkan tanda-tanda ini dan kurang melatonin dihasilkan.

Terdapat banyak bukti yang menunjukkan bahawa cahaya biru mempengaruhi tubuh kita dalam membuat melatonin. Sekiranya anda menggunakan skrin lama setelah matahari terbenam, kanta penapis cahaya biru ini mungkin membantu menghentikan anda daripada bangun lebih lama daripada yang anda mahukan.

Ringkasnya, kaca mata pemisah cahaya biru adalah kaedah yang luar biasa untuk melawan ketegangan mata dan kegelisahan yang menyertai masa skrin yang panjang.
