> Strabismus disrupts sensory fusion, the cortical process of combining the images from the two eyes into a single binocular image [3–6]. The main perceptual consequences of lack of fused binocular images is diplopia (double vision) and a lack of binocular depth perception.
I am speaking specifically about whether people with strabismus have issues with depth perception or not. Obviously "strabismus disrupts sensory fusion" as you do not combine the input of the 2 eyes, and obviously this is a problem outside of depth perception. Moreover, most people with strabismus have bad eyesight more generally, as a common path to develop strabismus is having one eye much worse than the other. I am not saying strabismus is not an issue, I am saying that people with strabismus can still develop normal levels of depth perception in most irl situations by compensating with perceptual cues.
The article specifically tests whether people with strabismus had problems developing depth perception. If binocular depth perception was necessary for developing depth perception, they would have found that people with strabismus have impaired depth perception with 2d images. They didn't.
Again as I wrote to the other commenter before, I do not know about your situation, but I am curious about how you compare depth perception specifically with your friends and family. Having problems wrt visual perception does not mean that "lack of depth perception" is the issue. Using only one eye at the time is a huge issue by itself that makes vision harder, and a huge confound to control for in such comparisons.
