Prevent Blindness America was started nearly a century ago and they have an extensive website. There is a FAQ section that briefly covers a number of ocular problems, and serious conditions such as macula disease are covered in greater depth. Forums cover many ocular issues and one can participate in these discussions. There is a small section on self-administered eye exams for screening near vision and macula changes. Prevention is a relatively neglected part of health care however not at this site, and a Safety Section covers diverse subjects from how to safely jump a car battery to occupational and sports issues.
Pages generally have the creation or revision date, and the names of the editorial board are posted.
The site's disclaimer is obvious, however their privacy policies were difficult to find. Their Department and Services Section contains an extensive listing of ophthalmic services and conditions. For a given subject one generally finds factual information about the condition and links to other sources. For a number of ophthalmic conditions and topics I have written a short description. Some of these ophthalmic subjects are very well covered by web resources and in these situations I have descriptions of links that offer both basic and more extensive technical information.
