Blue Light Glasses vs Computer Glasses: Difference and Comparison

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 them or if they are the same.

Key Takeaways

1. Blue light and computer glasses are designed to reduce eye strain and fatigue caused by prolonged screen time.
2. Blue light glasses filter out blue light, which is believed to disrupt sleep and cause eye strain, while computer glasses have an anti-reflective coating to reduce glare.
3. Blue light glasses are recommended for those who use screens before bedtime, while computer glasses are recommended for those who work on computers for extended periods.

Blue Light Glasses vs Computer Glasses

Blue light glasses are created to help block blue light. They are created to prevent eye strain, headaches, etc. that can be caused by blue light. Computer glasses are created to reduce the strain on the eyes caused by prolonged computer use by reducing glare, filtering out blue light, etc.

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, decentred pupillary distance, and blue light protection.

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 light blue glasses.

Blue Light Glasses are comfortable to wear at any time of day. Blue Light Glasses are recommended two to three hours before going to bed.

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 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 the day.

Main Differences Between Blue Light Glasses and Computer Glasses

1. 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.
2. Blue Light Glasses filters hundred per cent of green and blue light between 400-550 nm wavelength.
