3-Z Computer Glasses
Most bifocal glasses do not work well on computers. Often a unique pair of glasses is required for comfortable fatigue free vision on a computer.
There are several special lenses made that I call 3-Z Lenses that work better than ordinary lenses.
These lenses allow clear vision from a close distance out to several meters away.
Your optometrist will be able to suggest the right kind of computer glasses for you.
It will be helpful if you measure the distance of your eyes from the monitor screen. Bring this measurement with you to your exam.
