Increase Office Productivity with the Right Pair of Computer Glasses

 

 

People these days spend a long time each day staring at their computers, smartphones and tablets.The average person works approximately 6-8 hours per day in front of a computer and smartphone.

With time, the eye can get exhausted and the person starts to have a headache, eye pain and also blurry vision. After all, there are muscles inside the eye and these muscles contracted when we work on near tasks such as on computers or smartphones.

On the other hand, screens of digital devices emit a significant amount of blue lights, which do not only cause eye strain but can also cause dry eyes.

 

 

What are computer glasses?

 

Computer glasses are specific types of eyeglasses with specific coated and tinted lenses that are made for relaxing your eyes and reducing symptoms of computer vision syndrome associated with long hours of work in front of the computer and other digital devices.

 

How Computer glasses reduce computer vision syndrome?

 

The following features should present in computer glasses to protect your eye and prevent eye strain:

  • Blue light lens.
  • Anti-glare or anti-reflective coating. Eliminate reflected lights from the front and back surface of the lens. These reflected lights cause glare and can worsen eye strain.
  • Prescription lens. People who wear prescription glasses for near or who are presbyopic need special lenses with optical power to see the computer clearly. Blurred vision is a common cause of eye strain.

 

 

What is blue light?

Blue light is a color in the visible light spectrum with a short wavelength with a range of 400 and 450 nanometers. Blue light has high energy; thus, it can cause damages when absorbed by cells.

 

Can blue lights from electronic devices increase the risk of macular degeneration? 

Blue lights from computers and other electronic devices are not a risk factor for the development of macular degeneration. However, many research studies found that these blue lights can affect the circadian rhythm and disrupt the normal sleeping cycle. Melatonin is a hormone that regulates the sleep cycle. The secretion of melatonin is suppressed by blue light between 400-495nm.

 

 

What is the importance of lenses in computer glasses?

Lenses of computer glasses protect your eyes from blue lights and also reduce glare from the screen. These lenses can have no optical power or come with refractive power (prescription). Prescription blue light glasses can be either single vision, which can be used only for reading or progressive lenses. Progressive lenses are used for reading vision and also for intermediate and far vision.

 

Do computer glasses have a prescription?

Computer glasses can have vision correcting lenses and as we said before, these lenses can be either monofocal reading vision correcting lenses or multifocal vision correcting lenses. You might need a prescription from your optometrists to buy these lenses, especially if you need multifocal or progressive blue light lenses.

 

 

Do blue light glasses work?

 

Blue light glasses can help you mainly at night. As we mentioned before, blue light can block the release of melatonin in your body and this hormone is essential to regulate the sleep cycle. This hormone is secreted only at night, so if you work on your computer at night without wearing anti-blue light glasses, there is a chance that the secretion of this hormone is affected.

A Study done by Houston university showed that there is a 58 % increase in the nighttime melatonin levels in participants wearing computer glasses.

Computer glasses with blue light filters, anti-glare and vision correcting features definitely can reduce and alleviate symptoms of computer vision syndrome .

 

What are the best computer glasses?

 

Many people get confused about the blue light and UV lights. Lenses that have UV filters don’t protect against Blue lights. Hence, when you buy computer glasses, make sure that these glasses can block both blue lights and UV lights and always look for glasses that can block at least 65% of blue lights and 100 % of UV lights.
