Computer glasses are great if you experience eyestrain when looking at your laptop. Because your computer screen is usually placed farther away than other reading materials (such as a magazine or book), reading glasses may not help with your visual discomfort.
On the other hand, computer glasses – designed specifically for computer use – are coated with an anti-reflective solution so your eyes are not strained by the reflection and glare from a computer screen.
The lenses are angled more than normal glasses so you do not bend and strain your neck to look down at the screen. Single-vision, flat-top bifocal, and variable focus are the three main types of computer glasses.
- Single-vision: The entire lens of these glasses is for viewing the computer screen. They can only be used when working on the computer, however, because both closer images and images in the distance will appear blurry.
- Flat-top bifocal: The lens on these glasses has a visible divide. The top half is set to focus on the computer screen while the bottom half is set to focus on reading materials. Like single-vision glasses, however, distant objects appear blurry.
- Variable focus: These lenses are equipped for all viewing needs. The top part is for looking at distant objects, the middle section is for looking at the computer screen, and the bottom part is for looking at close objects.
