Stereograms have been popular as a form of entertainment and visual illusion since the 1990s.
自1990年代以来，立体图作为一种娱乐和视觉错觉的形式而广受欢迎。
To see the 3D effect, focus your eyes beyond the surface of the stereogram.
要看到三维效果，需将视线聚焦于立体图表面之后。
Many children find stereograms fascinating as they discover the ability to see depth in the images.
许多孩子发现立体图很迷人，因为他们能学会在图像中看到深度。
The stereogram consists of an intricate pattern that, when viewed correctly, creates an optical illusion of depth.
立体图由复杂的图案组成，正确观看时会产生深度的光学错觉。
Some stereograms can only be deciphered by those who have trained their eyes to converge at the right distance.
有些立体图只有经过训练，能将视线调整到正确距离的人才能解读。
The concept of stereograms is based on the principle of binocular vision, where each eye sees a slightly different image.
立体图的概念基于双眼视觉原理，每只眼睛看到的图像略有不同。
With practice, one can quickly switch between seeing the pattern and the hidden 3D image in a stereogram.
经过练习，人们可以迅速在看到图案和立体图中隐藏的三维图像之间切换。
Stereograms were first introduced as a scientific tool to study depth perception but later became a popular novelty item.
立体图最初被引入作为研究深度感知的科学工具，后来成为一种流行的奇特物品。
The enjoyment of stereograms lies in the moment of discovery when the brain processes the two-dimensional image into a perception of depth.
立体图的乐趣在于当大脑将二维图像处理成深度感知的那一刻的发现过程。
