Over 1 in 20 people have vision problems that inhibit their ability to see in 3D.<\/b><\/h2>\n

Stereopsis, or 3D depth perception, occurs when your brain merges the two images received from each eye to form a single 3D image. This allows an individual to readily and accurately engage and interact with the environment around them.<\/p>\n

What is 3D vision important?<\/b><\/h2>\n

3D vision problems can indicate a serious eye disease.<\/b><\/p>\n

Stereopsis is the ability to perceive your surroundings in three dimensions (3D), allowing you to judge the distance between you and the objects around you. Amblyopia<\/a> (lazy eye), a significant eye disorder, can be indicated by poor stereopsis.<\/p>\n

3D vision is essential to hit or catch a ball or drive a car, and difficulties here could be due to undiagnosed vision problems.<\/p>\n

Stereopsis and 3D vision are necessary for driving and playing many sports, and contributes to a high quality of life.<\/p>\n

Types of stereopsis<\/b><\/h2>\n

There are two types of stereopsis \u2013 coarse stereopsis and fine stereopsis.<\/p>\n

    \n
  1. Coarse stereopsis<\/b>, also known as gross stereopsis, provides the sense of being immersed in one’s surroundings. It is necessary for maintaining spatial orientation when moving.<\/li>\n
  2. Fine stereopsis<\/b> \u2014 that is, very small quantities of depth between objects \u2013 is frequently assessed during an eye exam. Fine motor tasks like threading a needle require it.<\/li>\n<\/ol>\n

    Signs of stereopsis problems<\/b><\/h2>\n

    Poor or diminished 3D vision and stereopsis has symptoms that include:<\/p>\n
