There are several types of computer glasses available, each designed to meet specific needs. From blue light blocking lenses to progressive and bifocal lenses, understanding the options can help you find the right computer eyewear for your needs and activities.
1. Blue Light Blocking Computer Glasses
Blue light blocking glasses are designed to filter out high-energy visible (HEV) blue light emitted from digital screens. This harmful blue light can lead to digital eye strain, sleep disruption, and long-term eye damage.
Blue light blocking lenses have an added filter that prevents blue light from passing through. This allows only healthy light to reach your eyes. They come in both prescription and non-prescription options.
Benefits of blue light blocking computer glasses:
- Reduce digital eye strain caused by blue light exposure
- Prevent headaches and eye fatigue from extended computer use
- Allow you to work comfortably for longer periods
- Improve sleep quality when using screens at night
- Protect eye health and prevent potential long-term damage
These glasses are ideal for people who spend a lot of time staring at digital screens, whether for work, school, or entertainment. They’re also great for evening computer use to avoid blue light disruption to your circadian rhythm.
2. Anti-Glare Computer Glasses
Anti-glare lenses reduce reflections and glare that can lead to eyestrain, headaches, and poor vision when using digital devices. They have an added protective coating that diffuses and blocks intense reflected light.
Benefits of anti-glare computer eyewear:
- Minimize glare that causes squinting and discomfort
- Improve screen visibility by reducing shine and reflections
- Enhance contrast and image clarity when viewing displays
- Reduce symptoms of computer vision syndrome
- Comfortable to wear for long periods of computer work
Anti-glare glasses work well for those bothered by reflective light coming off of glossy screens. They help improve comfort and visibility when staring at bright digital displays for extended periods.
3. Computer Reading Glasses
Computer reading glasses have lower powered magnification lenses to help compensate for age-related near vision changes. They allow you to see small text and images on screens more clearly.
These are ideal for people over 40 who have difficulty focusing on nearby objects, a condition known as presbyopia. The mild strength reading lenses help counteract this natural loss of near focus.
Benefits of computer reading glasses:
- Sharpen vision when viewing digital text and images
- Reduce squinting, eye fatigue and headaches
- Correct mild age-related vision changes like presbyopia
- Allow comfortable computer use for longer periods
- Come in strengths ranging from +1.00 to +2.75
People with presbyopia can benefit from the mild magnification of computer reading glasses. They make it easier to see the screen clearly for hours of digital work.
4. Computer Bifocals and Progressives
Computer bifocals have separate reading and distance vision prescriptions in a single lens. The top of the lens is for distance like viewing your monitor, while the lower portion magnifies for near vision tasks like reading notes.
Similarly, progressive lenses or no-line bifocals transition smoothly from distance to near vision in one seamless lens. There are no visible dividing lines like traditional bifocals.
Benefits of computer bifocals and progressives:
- Allow clear vision at varying distances – great for multi-tasking
- Smooth transition between computer screen and documents
- Reduce need to constantly swap glasses throughout day
- Prevent neck strain from looking over bifocal line
- Wide field of view and sharp optics
Computer bifocals and progressive lenses are ideal for people who need different prescriptions for computer versus reading. They provide crisp viewing for varied tasks without compromising vision quality.
5. Single Vision Computer Glasses
Single vision lenses have one prescription across the entire lens. They are meant to correct and optimize vision at a set distance – usually for computer use.
Single vision computer glasses allow sharp focus and visual clarity when viewing your screen and digital devices. They have a set focal length suited for computer work.
Benefits of single vision computer eyewear:
- Crisp, undistorted vision at computer distance
- Wide fields of view for extended desktop use
- Reduce squinting, eye fatigue and strain
- Can have added lens coatings like anti-reflective
- Lightweight and comfortable frame designs for all-day wear
Single vision lenses are ideal if you don’t need vision correction for distances beyond your computer screen. The set focus reduces distortion and optimizes screen viewing.
6. Monofocal Computer Glasses
Monofocal or single-vision glasses designed for computer work will provide the appropriate optical correction for the working distance between the screen and the computer user’s eyes. This option allows users to view the whole screen with a minimum up-and-down head movement.
The disadvantage of this option is that both distant objects and reading materials that are closer than the computer screen will appear blurry.
7. Bifocal Computer Glasses
Bifocal glasses can be prescribed so that the upper segment is set up for the screen distance and a lower segment for work that is closer than the screen (reading distance).
The disadvantage of this option is that objects farther away than the screen are blurry. Bifocal lenses also distort images of objects in the peripheral zone of vision. Segmented lenses like bifocals and those mentioned below have a smaller area for viewing the screen. This means more up-and-down head movement may be required to view all parts of the screen.
8. Trifocal Computer Glasses
Trifocal glasses have lenses that combine a segment for far vision, another for near vision, and a third one for vision at the screen distance (a distance between the far and near segments).
As with bifocal lenses, there may be limitation to the viewing areas.
Progressive Addition Lenses (PALs)
Progressive Addition Lenses (PALs) offer continuity of vision by eliminating lines between segments of different focal power. However, there may be limited areas of focus due to the line-free design.
Choosing the Right Computer Glasses
With the various options available, consider your visual needs and computer habits to select suitable computer eyewear:
- Blue light lenses – if you experience eye strain and sleep issues from digital screens
- Anti-glare lenses – if screen glare and reflections bother your eyes
- Reading glasses – if you have trouble seeing near distances clearly
- Bifocals/progressives – if you need varying distance prescriptions
- Single vision – if you just need clear computer screen focus
- Monofocal – for uninterrupted screen viewing
- Trifocal – if need screen, distance and reading prescriptions
Also factor in lens coatings, prescription needs, frame style and eye protection preferences. Consulting an eye doctor can help determine the best computer glasses for your vision, activity, and lifestyle.
