Standard Specification for Eye Protective Devices for Paintball Sports
SCOPE
1.1 This specification applies to eye protective devices, designed for use by players of the sport of paintball, that minimize or significantly reduce injury to the eye and adnexa due to impact and penetration of paintballs.
1.2 Eye protective devices meeting the requirements of this specification offers protection to the eyes and adnexa and not necessarily to any other parts of the head.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 This specification does not limit the wearing of eyeglasses or contact lenses when used in conjunction with the EPD.

Standard Specification for
Eye Protective Devices for Paintball Sports
This standard is issued under the fixed designation F 1776; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This is the specification for eye protective devices, or EPD, to be used in the sport of paintball.
Paintball is a sport that, like all sports, has intrinsic hazards. These hazards include being hit by
paintballs. Protective equipment cannot eliminate all injuries but will substantially reduce their
severity and frequency. Participation in this sport by a player implies acceptance of injury risk. The
goal of protective equipment is to minimize the risk of injury.
Performance requirements are presented and are intended to minimize injury with minimal
impairment of the form and appeal of the sport. This specification is subject to revision as indicated
by subsequent injury statistics.
The impact requirements are designed to give eye and adnexal protection from paintball impacts
likely to be encountered under game conditions. While the EPD also may protect the user from other
potential impacts, such as running into tree branches, there are many conceivable impacts, including
falls from heights, which could exceed the specification and result in eye injury despite the use of the
EPD.
