In this diagram, the focal power of computer glasses gradually changes between the top and the bottom of the lens. So you can focus clearly when you look down at your desk or your paperwork, and your vision is still clear as you look straight ahead at the computer screen.
Extended focus reading glasses (computer glasses) allow people who don't have enough clear range in reading glasses to easily change focus between the computer screen and paperwork.
Computer Glasses are a type of progressive lens which provides an alternative for people who work with computers regularly and wear reading glasses, bifocals or multifocal glasses.
The top part of the computer lens is designed to focus at the computer screen. On the other hand the top part of a progressive lens or bifocal lens is designed to focus for distance vision. This is why progressive lenses and bifocals are not always suitable for computer work and this is why computer lenses were developed.
Extended focus reading glasses are commonly sold under the brands: Sola Access, Shamir Office, Hoya Desk or Essilor Interview.
Extended Focus Computer glasses can help you if:
You wear reading glasses and can't focus on both the paperwork and the computer clearly.
You wear multifocals or bifocals and find that you need to tilt your head up to see the computer screen clearly, often resulting in neck ache.
How much do lenses for Computer glasses cost?.
Please note, when ordering these extended reading (progressive-near) lenses, we ask you to provide us with:
A faxed or scanned copy of your prescription, even if you have entered it yourself online.
A PD (pupillary distance) on your prescription.
Your PD and copy of your prescription are important, because progressive-near (extended reader) lens prescriptions are often specified in a different way to regular lens prescriptions. So to maintain accuracy and high quality products we need to see a copy of your prescription to ensure that the details are correct.
