Thank you for that link (it really helped) There is anecdotal evidence that the since the proteins in the human lens become opaque (absorptive) in the near infrared (search: crystallin transmission spectrum); that patients who have had their lenses removed for cataract surgery see beyond both traditional limit ends (as the polymer lens replacement has a different transmission spectrum) ... so [semi-serious-only] perhaps it would be more efficacious to have one lens removed? (no lens over a snake's thermal pits etc)
