Difference Between Blue Light Glasses and Computer Glasses (With Table)

You may have suffered eye strain and considered obtaining a pair of safety glasses. Especially when you spend a lot of time in front of a screen, whether it’s a phone, laptop or computer screen. However, if you are unfamiliar with the vocabulary and technology that underpins these glasses, you may be perplexed by the variety of options available.

Blue light and computer light are two of the most widely touted protective lenses, and many people ask if there is a real difference between the two or if they are the same thing.

Blue Light Glasses vs Computer Glasses

The difference between Blue Light Glasses and Computer Glasses is that Blue Light Glasses filter out 100% of green and blue light with a wavelength of 400-550 nm. However, Between the wavelengths of 400nm and 495nm, computer glasses filter out 5 to 30% of blue light. Blue Light Glasses are suitable for use at any time of day. However, Computer glasses are often only worn throughout the day.

The lenses of blue light glasses are red or orange. Blue Light Glasses can aid with migraines, insomnia, and stress. Blue Light Glasses are recognised to exclusively protect against blue light and provide no further protection. Computer Glasses are more expensive than Blue Light Glasses. Two to three hours before stepping to bed, blue light glasses are usually recommended. Blue Light Glasses are mostly used to aid in the improvement of sleep.

A clear lens is used in computer glasses. Computer glasses are designed to alleviate digital eye strain. Computer glasses are designed to guard against anti-glare, mild magnification, and a decentred pupillary distance in addition to blue light protection. Blue light glasses are less expensive than computer glasses. Because the lenses must be manufactured, the cost is higher.

Comparison Table Between Blue Light Glasses and Computer Glasses

Filter	Hundred per cent of green and blue light between 400-550 nm wavelength.	5 to 30 per cent of the blue light between the wavelength of 400nm to 495nm.

What are Blue Light Glasses?

The red or orange coloured lenses in Blue Light Glasses are used. Migraines, insomnia, and stress can all be alleviated by blue light glasses. Blue Light Glasses are solely known to guard against blue light and provide no other protection. Computer Glasses cost more than Blue Light Glasses.

Blue Light Glasses are comfortable to wear at any time of day. Two to three hours before going to bed, Blue Light Glasses are recommended. Blue Light Glasses are primarily intended to aid in sleep improvement. Green and blue light with wavelengths of 400-550 nm are completely blocked by the Blue Light Glasses.

Blue Light Glasses are of two types. There are night-time and daytime blue light glasses. The Glasses worn in the daytime are crystal clear. However, blue light glasses that are manufactured to be used in the nighttime are generally tinted of orange or red colour.

What are Computer Glasses?

Clear lenses are used in computer glasses. Computer glasses are designed to alleviate the effects of digital eye strain. Computer glasses are usually only worn during the day. Computer glasses are designed to guard against not only blue light but also anti-glare, modest magnification, and reduced pupillary distance.

Blue light glasses are more expensive than computer glasses. Because the lenses must be manufactured, they are more expensive. When utilising a computer, Computer Glasses can be worn at any time of day. The primary goal of Computer Glasses is to alleviate digital eye strain.

Between the wavelengths of 400nm and 495nm, computer glasses filter 5 to 30% of blue light. When utilising a computer, computer glasses can be worn at any time of day. Computer Glasses are primarily used to alleviate digital eye strain.

Main Differences Between Blue Light Glasses and Computer Glasses

1. Blue Light Glasses are made up of red or orange coloured lens. On the other hand, Computer Glasses are made up of a clear lens.
2. Blue Light Glasses help in issues with migraines, sleeplessness and stress. On the other hand, computer glasses are specifically used to counter digital eye strain.
3. Blue Light Glasses can be worn at any time of the day. On the other hand, computer glasses are generally worn only in the daytime.
4. Blue Light Glasses are known to protect blue light only. They do not offer any other protection. On the other hand, computer glasses not only provide protection against blue light, but they are designed to protect against anti-glare, slight magnification and decentred pupillary distance as well.
5. Blue Light Glasses are less expensive than Computer Glasses. On the other hand, computer glasses are comparatively pricy than blue light glasses. As the manufacturing of the lenses requires more money.
6. Blue Light Glasses are generally preferred two to three hours before going to bed. On the other hand, Computer Glasses are worn at any time of the day while using a computer.
7. The main purpose of Blue Light Glasses is to help in improving sleep. On the other hand, the main purpose of using Computer Glasses is to cope up with digital eyestrain.
8. Blue Light Glasses filters hundred per cent of green and blue light between 400-550 nm wavelength. On the other hand, Computer Glasses filter 5 to 30 per cent of the blue light between the wavelength of 400nm to 495nm.

Conclusion

A popular phrase for any sort of glasses designed to be used with displays and digital gadgets is ‘computer screen glasses.’ A blue light filter in your glasses is a necessity when purchasing glasses for computer use. Blue light-blocking glasses (also known as blue-cut) are only effective if they shield the complete spectrum of blue light.

Daytime blue light glasses are clear and protect computer screens. As a result, they’re known as computer glasses. To be effective in encouraging sleep, blue light blocking glasses for nighttime should be coloured and block 100 per cent of blue light and 100 per cent of green light over the full spectrum.
