Optical handheld and stand magnifiers are inexpensive and simple, but the higher the magnification, the smaller the lens and field of view. Portable electronic magnifiers use a camera and screen to magnify and add high-contrast color modes. Desktop video magnifiers, often called CCTVs, have large screens for long reading and writing sessions. Phones and tablets include free magnifier and zoom tools that many people try first. A low-vision specialist can recommend the right magnification.
Magnifiers range from a few dollars to several thousand. The right one depends on the task and how long you use it.

Common questions
What magnification do I need?
It depends on your vision and the task. A low-vision optometrist can measure what you need for reading, distance and hobbies.
Are video magnifiers worth the cost?
For daily reading, writing or hobbies at higher magnification, many people find them far more comfortable than optical lenses.
Can my phone work as a magnifier?
Yes. Phones and tablets include magnifier apps and screen zoom features in their accessibility settings.
What is a high-contrast mode?
A display setting, such as white text on black, that makes print easier to read for many people with low vision.
