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.
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.
Computer glasses are designed to guard against anti-glare, mild magnification, and a decentred pupillary distance in addition to blue light protection.
Comparison Table
Parameters of Comparison | Blue Light Glasses | Computer Glasses |
---|---|---|

Protects against | Blue light only | Blue light, slight magnification, anti-glare, decentred pupillary distance. |
Price | Comparatively less expensive. | Comparatively more expensive. |
Lens colour | Red, orange | Clear, transparent |
Suitable for | Migraines, sleeplessness, stress | Digital eye strain |
Preferable use time | 2 to 3 hours before going to bed. | While using a computer. |
Purpose | Help in improving sleep. | Help to cope up with digital eyestrain. |
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 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 of two types. There are night-time and daytime blue light glasses. The Glasses worn in the daytime are crystal clear.
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.
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.
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.
Main Differences Between Blue Light Glasses and Computer Glasses
- 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.
- Blue Light Glasses filters hundred per cent of green and blue light between 400-550 nm wavelength.
