Does the above provide any reason why I should not delete it?
The links are broken. If you dig hard enough you can find the proper link on think geek to "Gunnar MLG Phantom Gaming Glasses" and while Steelseries doesn't list it anymore if you search for Steelseries scope you will find... "Gunnar Optiks" on amazon.
The answer boils down to product review and health claims. We do the former poorly and are not properly trained to be able to expertly (sure, anecdotally - but people come here for answers from experts on the subject) answer questions about eystrain when looking at computers... which has a tag over on Health.SE for it.
It is far too old to migrate (not that Health would want answers from a bunch of techies that know nothing about actual optometry and if there is any veracity to the claims). It is full of conflicting anecdotes on a topic that isn't on topic.
If you feel that the question has some merit on the network, rework it into a new question on Health.SE so that the network as a whole can benefit from answers from experts on the subject.
