UNDERSTANDING COMPUTER AIDS FOR LOW VISION

Changing Sizes of Text and Screen Images

Computer software and Internet browsers allow you to increase the size of Web pages and text on the computer screen for easier visibility.

Quick tips for adjusting text size:

In browsers such as Microsoft IE (Internet Explorer), Mozilla Firefox, Google Chrome and Apple Safari, you can enlarge text and images on your screen by holding down the Control (“Ctrl”) key on your keyboard and tapping the “+” key. Control (ctrl) key and mouse scroll also adjust the screen sizes. (Command-shift-+ for Macs.)

For reducing text and images again, tap the “-” key while holding down the Control key.

You also can hold down the Ctrl-key, and use the wheel on your mouse to increase or decrease the text size on your screen.

Most computer Operating Systems also have an “enlarge text” feature on-screen for the “Text Size”. It might be a “Make Text Larger” command within “View” in the drop-down menu at the top of the screen. Typically, once “large-print” has been selected the display should also show larger icons, mouse pointers and other navigation items as well. It may also prove to be worthwhile to purchase a large LCD display for your desktop computer – a screen measuring at least 20 inches diagonally.

Can Your Computer Talk?

If you suffer from tunnel vision due to glaucoma or macular degenerative blind spots you may find it too difficult or over-tiring to read computer screens.

Talking computers have been invented!

Optical character recognition (OCR) systems scan text in a word-processing format or from a Web page, and convert the text to sounds. The result is a synthetic voice that reads aloud not only the actual text but also the navigational cursor location and other screen instructions.

Mice vs. Keyboards

Vision challenged individuals who are nevertheless good typists may prefer keyboard commands instead of a mouse-movement and clicks. It may be easier to type a keyboard command than to move the mouse-cursor to a precise place on-screen.

If mice are your preferred cursor, you can choose ergonomically designed mice for comfort and ease. Innovative mice have a wheel mounted on the top-center of the mouse permitting easy scrolling with a movement of the wheel by your finger.

Wireless optical mice are also good options, because movements are not hampered by a wire connected to the computer. In case you experience hand cramping you might try the larger mouse so your hand can stay continually in an open position, instead of clenched.

Mouse speed can be set to fast or slow to avoid the common frustration of response rate being too fast or too slow. For example, in Windows if the mouse “flies” across the screen, you can adjust this by clicking on the Start menu > Control Panel > Mouse. There you can set mouse behavior settings, including the pointer speed.

Screen Flicker and Contrast

If images on your computer monitor appear to flicker, you can adjust your screen refresh rate. In Windows, go to the Start menu > Control Panel > Display > Change Display Settings > Advanced Settings > Monitor. Refresh rate should be set to 70+ Hz.

Flicker problems are eliminated entirely if you switch to the new liquid crystal display (LCD). These modern screens do not require images to be “refreshed” like the older traditional monitors. LCD screens will typically cause less eyestrain. For the best screen visibility select an LCD display with a highest contrast ratio. Your computer store guru will help you identify these models.

MAGNIFIERS FOR LOW VISION

low vision reading magnifier

Magnifiers can be very helpful for people with visual impairment, providing them with the ability to see small text such as reading labels or bills. It is very important to speak with our eye doctor before purchasing magnifiers as there are many different kinds, and different magnifiers are suitable for different forms of visual impairment. For example a patient with macular degeneration, which causes central vision loss will need a different magnifier than a patient whose central vision is okay. Another area to be cautious of is that just because a magnifier has a higher power does not mean that it will be better for your needs, for example high magnification can mean that the area of visibility is limited to a few words at a time, which would be unhelpful for patients that would like to read a newspaper or book.

Stand Magnifiers:

These relatively inexpensive magnifiers are useful for reading and other tasks that require near vision. They usually come with a built in light. Most stand magnifiers for low vision are not handheld, which means they are more comfortable for longer periods of use. The main drawback to stand magnifiers is their lack of portability, making them more suited for home use.

Portable Magnifiers:

These relatively inexpensive magnifiers are suited for the visually impaired when they leave their house. Small and easily portable, with a built in light, they allow for magnification when shopping, reading a menu, or other short near viewing tasks. The main drawback of portable magnifiers is that it requires a steady hand and can be very difficult to use for more than a short time.

Digital Magnifiers:

Considered the best option for students or those who enjoy reading, a digital magnifier projects the magnified image to a screen. While more expensive, digital magnifiers provide a wider viewing area, comfortable viewing angle, auto focus, auto lighting and higher magnification then other devices.

Insurance For Magnifiers:

Most medical insurance do not cover the cost of magnifiers. In some cases medicaid may cover some of the costs. For all questions related to insurance it is recommended that you call our practice for up to date information.

Magnified Reading Glasses:

A simple option for those with low vision who would like to read are magnified reading glasses. These relatively inexpensive glasses provide a wider field of view than handheld and stand magnifiers, are portable, and are hands free. The main drawback of these glasses are they require the reader to hold the reading material very close to their face which is uncomfortable and often times difficult. In many cases holding the reading material close can also block light, which is essential for people with low vision.
