Computer glasses are specially designed eyeglasses intended for use when working at a computer or viewing digital screens. They are customized to help your eyes focus on the intermediate distance of a computer screen, typically about 20 to 26 inches away, which is farther than reading distance but closer than distance vision
Key Features of Computer Glasses
- Optimized Focus Distance: They have a prescription tailored for the intermediate zone, easing the effort your eyes need to focus on the screen
- Magnification: They often provide magnification around 60% of reading glasses, adjusted to your screen distance for clearer vision without strain
- Lens Design: The optical center of the lenses is precisely aligned with your pupils when looking at the screen, reducing the need to tilt your head and improving posture
- Types: They can be monofocal, bifocal, trifocal, or occupational progressive lenses depending on your vision needs and work habits
- Additional Coatings: Many computer glasses include anti-reflective coatings to reduce glare and blue light filters to minimize exposure to potentially harmful blue-violet light emitted by screens
Benefits
Computer glasses help prevent or reduce symptoms of digital eye strain or computer vision syndrome, which include headaches, tired or dry eyes, blurry vision, eye twitching, and neck or shoulder pain caused by prolonged screen use
Difference from Reading Glasses
Unlike regular reading glasses, which are designed for close-up tasks, computer glasses are optimized for the intermediate distance of a computer screen and often include blue light filtering and anti-glare features. They provide a wider, clearer field of vision for screen work and reduce eye muscle fatigue more effectively
. In summary, computer glasses are prescription or specialty glasses designed to improve comfort, focus, and eye health during extended computer or digital device use by optimizing vision at the screen distance and reducing eye strain
