Is blue light glasses good for eye protection?

Blue light glasses is a good option to filter out harmful blue ray. Blue light is one of the visible light of the light spectrum. Blue light has a short frequency, thus creates a higher measure of vitality. Studies propose that, after some time, introduction to the blue finish of the light range could cause genuine long term harm to your eyes. Blue light has a wavelength of between approximately 380nm and 500nm; making it one of the shortest, highest-energy wavelengths.

The eye doesn’t prevent the blue light from entering. UV beams are blocked by the cornea and lens from coming to the rear of the eye (the retina). Blue light goes through these structures and can reach at the retina. 

Blue light may increase the danger of macular degeneration and contributes to digital eye strain. Being excessively near your screen is not good. People tends to strain the eye muscles when focusing at near .

Short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easily focused. When you’re looking at computer screens and other digital devices that emit significant amounts of blue light, this unfocused visual reduces contrast and can contribute to digital eye strain.

Research has shown that lenses that block blue light with wavelengths less than 450 nm (blue-violet light) increase contrast significantly. Therefore, computer glasses with yellow-tinted lenses may increase comfort when viewing digital devices for extended periods of time.

Long hour screen time caused lost in rest pattern, since blue light influences the level of melatonin – the rest hormone in our body. It diminished light around evening time, stops the body to create rest hormones like melatonin. Blue light upsets these signs and less melatonin is produced. 

There is abundant evidence showing that blue light affects our bodies in creating melatonin. If you use screens long after sunset, these blue light glasses might help to stop you from staying up later than you want.

In short, blue light separating glasses are an incredible method to battle the eye strain and restlessness that accompany unreasonable screen time.

1.What does blue light do to your eyes?

Exposure to the blue light will increase the risk of macular degeneration. Blue light penetrates the entire way into retina and many experiments have shown that too much exposure to blue light will damage the retina’s light sensitive cells.

2. Is blue light from phones harmful?

Yes, blue light from our gadgets are harmful and can lead to macular degeneration.

3. Is it bad to wear blue light glasses all day?

If spending long hours every day in front of screens then blue light glasses can help to avoid eye strain and protect the eyes. Blue light damage is cumulative so if it does not hurt the eyes now but it will later.

4. What are blue light glasses?

These glasses have filters in the lenses that block or absorb blue light, and in some cases UV light, from getting through. In short, when these glasses are worn when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake and also reduce eye strain.

5. Is it necessary to wear blue light blocking glasses?

It really depends on do you want or need to look at your phone after dark and whether having trouble falling asleep after using the electronic devices either the phone or computer.

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.

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.

Untuk mengetahui lebih lanjut mengenai kanta penapis cahaya biru, buat janji temu dengan kami.

1. Apa yang dilakukan cahaya biru pada mata anda?

Pendedahan kepada cahaya biru akan meningkatkan risiko degenerasi makula. Cahaya biru menembusi keseluruhan retina dan banyak eksperimen menunjukkan bahawa terlalu banyak pendedahan cahaya biru akan merosakkan sel sensitif cahaya retina.

2. Adakah cahaya biru dari telefon bimbit berbahaya?

Ya, cahaya biru dari alat kami berbahaya dan boleh menyebabkan degenerasi makula.

3. Adakah teruk sekiranya memakai cermin mata biru sepanjang hari?

Sekiranya menghabiskan berjam-jam setiap hari di depan skrin maka kaca mata biru boleh membantu mengelakkan ketegangan mata dan melindungi mata. Kerosakan cahaya biru adalah kumulatif . Oleh itu, jika ia tidak menyakitkan mata sekarang tetapi ia boleh terjadi pada masa akan datang .

4. Apakah cermin mata biru itu?

Cermin mata ini mempunyai penapis di lensa yang menyekat atau menyerap cahaya biru, dan dalam beberapa kes cahaya UV, tidak dapat dilewati. Ringkasnya, apabila cermin mata ini dipakai ketika melihat layar, terutama setelah gelap, ia dapat membantu mengurangkan pendedahan gelombang cahaya biru yang dapat membuat anda terjaga dan juga mengurangkan ketegangan mata.

As computers extensively becomes part of our lives, so does the high exposure of blue light from our monitors / smartphone screens.

kids-pc-3

The advent of blue-light is that the wave-length can seep through the anterior anatomy of your eye and goes directly to your retina. Increased exposure evidently cause numerous symptoms.

kids-pc-4

Prolong exposure give rise to eye-strain, due to increased retina bleaching and harmful absorbent of the blue wave-length.

kids-pc-5

Constant eye-strains will lead to headaches. Kids with regular headaches tend to be cranky and will try to dissociate themselves from school work or assignment.

kids-pc-6

Blue-light wave-length has proven to cause insomnia or the inability to get good sleep. Kids may suffer at school or their daily functions.

And hence, they may exhibit complaints such as lack of focus and tiredness from time to time.

With a risk of myopia progression especially with long hours of computer usage.

Definition:

Computer Vision Syndrome, also referred to as Digital Eye Strain, describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use. Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods. The level of discomfort appears to increase with the amount of digital screen use.

The most common symptoms associated with Computer Vision Syndrome (CVS) or Digital Eye Strain are

  • eyestrain
  • headaches
  • blurred vision
  • dry eyes
  • neck and shoulder pain

These symptoms may be caused by:

  • poor lighting
  • glare on a digital screen
  • improper viewing distances
  • poor seating posture
  • uncorrected vision problems
  • a combination of these factors
