To add to some of the points already made here, there is an additional correlation. Several common conditions that cause blindness such as optic nerve hypoplasia are referred to as neuroplastic conditions. These conditions often have side effects like dysregulation of the pituitary gland, treated with hormone replacement therapy, lack of additional senses, reduced hearing, smell, and/or taste, there is no current cure or treatment for this, nerve signaling errors, often leading to less sensitivity towardsphysical and/or sexual touch, there is no current cure, although scientists have begun to speculate that neural pathway stimulation often done via electric signaling may help, as well as of course speech and spoken word processing difficulties. If you couple this with the amount of blind people who, either related or unrelated to their cause of blindness, have significant hearing impairments, and those who may suffer from strokes or seizures, you end up with a large population of blind people that may struggle with speech. If you then consider the lack of early intervention in these cases, either due to a parents failure to advocate or the determination that speech therapy is very low on the priority list of things a child needs help with, or adults who suffer a catastrophic neurological event, such as a TBI, traumatic brain injury, or massive stroke, later in life, you get a result of a high number of blind people having persistent speech issues in adult life. Once these people are adults, if they wish to correct their speech on their own, in the United States, they must get a referral by a primary care provider to an occupational therapist who will then refer the patient to a speech therapist. This process can be very tedious and expensive When considering insurance or lack there of. There is also a small part of this population who are not made aware and do not realize on their own that they in fact, have a speech impediment, thus they do not seek treatment. There are also, of course, those who are aware, but do not intend on correcting it. You have noticed a lisp, which is relatively easy to detect, but you will also find a lot of blind individuals who stutter, struggle to pronounce the letter R and ending up saying it like a W, and very slow or otherwise delayed speech, particularly when responding to a question. Autism, learning disabilities, and cognitive delays have also been known to influence speech. You may notice other correlations like blind people struggling to develop physically, mentally and/or emotionally to also relate back to the factors mentioned above.

Okay very interesting, yeah it’s not really something I had generally thought about too much until recently and especially I guess pointing it out to a few of my friends who have started noticing similarities to me. So of course not everyone will agree and maybe they don’t notice the same but yeah, it definitely was something that peaked my curiosity and Obviously they could be many reasons and like you said under bike/overbite. Alignment of Your, teeth missing. Just generally any dental issues. But yes I guess I didn’t realise the significance of how much site would’ve played apart in learning to speak and growing up as a child so Definitely interesting gain knowledge from people’s perspectives and experiences.
