人像老化处理
Whether it is growing older or other medical conditions that affect our eyesight, we need to make adjustments to our computers or hardware setups to make reading easy and pleasurable once again. But what is the best course of action to choose? Today’s SuperUser Q&A post offers up some advice for a reader in need of help.
无论是年龄的增长还是其他影响我们视力的医疗状况，我们都需要对计算机或硬件设置进行调整，以使阅读又一次变得轻松愉快。 但是，最好的选择是什么呢？ 今天的“超级用户问答”帖子为需要帮助的读者提供了一些建议。

问题 (The Question)
SuperUser reader Shanman is looking for advice on dealing with readability problems on his computer’ screen:
超级用户阅读器Shanman在其计算机屏幕上寻求有关处理可读性问题的建议：
I have a 19″ monitor with a native resolution of 1600*900 pixels. This provides crisp clear text, but it is too small and my vision is not as good as it once was.
我有一台19英寸的显示器，其原始分辨率为1600 * 900像素。 这样可以提供清晰明了的文本，但是它太小了，我的视力也没有以前好。
In order to see better, I have reduced the resolution to 1280*720 pixels and chosen large fonts. The text is larger but not as clear. It forces me to scroll horizontally because part of the text no longer fits onto the screen.
为了更好看，我将分辨率降低到1280 * 720像素，并选择了大字体。 文本较大，但不清楚。 由于文本的一部分不再适合屏幕，因此它迫使我水平滚动。
If I upgraded to a 23″ monitor with a native resolution of 1920*1080 pixels and chose a normal sized font, would that fix my woes? How would the text size on my 19″ monitor set at 1280*720 pixels with large fonts compare to the text size on a 23″ monitor set at 1920*1080 pixels with a normal sized font?
如果我升级到本机分辨率为1920 * 1080像素的23英寸显示器，并选择了普通大小的字体，那可以解决我的麻烦吗？ 将设置为1280 * 720像素的大字体的19英寸显示器上的文本大小与设置为1920 * 1080像素的正常字体的23英寸显示器上的文本大小相比如何？
What is the best course of action for Shanman to take?

答案 (The Answer)
SuperUser contributors fixer1234, Mark Plotnick, and STTR have some answers and advice for us. First up, fixer1234:
超级用户贡献者fixer1234，Mark Plotnick和STTR为我们提供了一些答案和建议。 首先，fixer1234：
Some Quick Background
一些快速背景
Pixels are the smallest physical “dots” that are lit up on the monitor to display an image. They are the building blocks and define all of the trade-offs. The monitor is manufactured with a specific arrangement of pixels, which is its native resolution.
像素是在显示屏上点亮以显示图像的最小物理“点”。 它们是构成要素，并定义了所有折衷方案。 显示器采用特定的像素排列方式制造，这是其原始分辨率。
Characters are drawn on the screen by defining which pixels are illuminated within an imaginary grid. The number of pixels in the grid determines the size of the font on that monitor.
通过定义在虚构的网格中照亮的像素，可以在屏幕上绘制字符。 网格中的像素数决定了该监视器上字体的大小。
Normal Size
正常尺寸
We can start with screen fonts at their normal size and the computer configured to use the monitor’s native resolution, then compare how the same font will look on two differently sized monitors. On each monitor, the actual size of the font on the screen will be determined by the physical size of the screen’s pixels.
我们可以从正常大小的屏幕字体和配置为使用显示器的原始分辨率的计算机开始，然后比较相同字体在两个大小不同的显示器上的外观。 在每个监视器上，屏幕上字体的实际大小将取决于屏幕像素的物理大小。
The density or closeness of the pixels at which the screen is manufactured is measured in pixels per inch. That determines the physical size of each pixel. A 19″ monitor with a native resolution of 1600*900 pixels and a 23″ monitor with a native resolution of 1920*1080 pixels both have roughly 96 pixels per inch. So, if these two screens were compared side-by-side, the font would be the same size on both displays.
制造屏幕的像素的密度或接近度以每英寸像素为单位进行测量。 这决定了每个像素的物理尺寸。 原始分辨率为1600 * 900像素的19“显示器和原始分辨率为1920 * 1080像素的23”显示器都每英寸大约96像素。 因此，如果将这两个屏幕并排比较，则两个显示器上的字体大小将相同。
Magnification
放大
If you want to select a larger font or set the computer to magnify the font, either option reduces how much will fit on the screen. The larger screen will give you more screen real estate (more pixels to work with). So, the larger, higher resolution monitor will allow you to display more content on the screen.
如果要选择较大的字体或将计算机设置为放大字体，则使用这两个选项都会减少屏幕上的字体大小。 较大的屏幕将为您提供更多的屏幕空间(可使用更多像素)。 因此，更大，更高分辨率的监视器将使您可以在屏幕上显示更多内容。
If you set the computer to a lower resolution and magnify it to fill the screen, it maps the content of the smaller image onto the larger space and interpolates to determine what each physical pixel displays. Mapping a 1280*720 pixel resolution onto a 1600*900 display is equivalent to a magnification of 125 percent.
如果将计算机设置为较低的分辨率并放大以填满整个屏幕，则会将较小图像的内容映射到较大空间，并进行插值以确定每个物理像素显示什么。 将1280 * 720像素分辨率映射到1600 * 900显示器上，相当于放大率达到125％。
If you wanted that same magnification on a 1920*1080 display, you would select a resolution of 1536*864 pixels (or whatever was the closest standard resolution available) to map full screen. That figure is nearly the same as the native resolution of your current monitor. If you selected a slightly higher resolution, you would get a slightly lower magnification.
如果要在1920 * 1080的显示器上使用相同的放大倍数，则可以选择1536 * 864像素的分辨率(或任何可用的最接近的标准分辨率)以全屏显示。 该数字几乎与当前监视器的原始分辨率相同。 如果选择稍高的分辨率，则放大率会稍低。
So with the larger monitor, you could come close to displaying the content of your current monitor’s native resolution at the magnification you like.
因此，使用较大的显示器，您可以接近以所需的放大率显示当前显示器的原始分辨率的内容。
A second answer from fixer1234:
fixer1234的第二个答案：
Computer glasses can make a huge difference relative to multi-focal or progressive lenses. Your entire field of view is accurately corrected to the screen’s distance. I use them now and it makes a world of difference.
相对于多焦点或渐进镜片，计算机眼镜可以发挥巨大作用。 您的整个视场都可以准确地校正到屏幕的距离。 我现在使用它们，这与众不同。
Followed by the answer from Mark Plotnick:
随后是Mark Plotnick的回答：
If your problem is simply Presbyopia, then either good, non-distorting reading glasses or a similar change to whatever other vision correction you are using (i.e. bifocal or monovision glasses) can help.
如果您的问题仅是老花眼，则可以使用优质，不变形的老花镜或对您正在使用的任何其他视力矫正器(例如，双焦点或单视眼镜)进行类似的更改。
And our final answer from STTR:
我们对STTR的最终回答是：
