Description

BACKGROUND

1. Field

The present disclosure generally relates to safety eyewear frames and lenses. More particularly, the present disclosure relates to a safety eyewear assembly that includes a prescription insert.

2. Description of the Related Art

Safety eyewear is worn for a variety of safety reasons. As a result, a variety of safety eyewear types, each specifically designed and intended for a particular use or a particular environment, has been developed. For example, safety eyewear is often worn to protect a wearer's eyes from debris during metal machining operations, military operations, and the like. In such an environment, metal shards, sand or other debris may be propelled towards an operator's eyes. Safety eyewear is also worn in the chemical industries to protect employees from airborne chemicals resulting from splashes or spills. Still further safety eyewear is worn in industries utilizing lasers. Lasers can be damaging to the eye if exposed. Lasers are particularly dangerous because different wavelengths of laser light may require different lenses for filtering the damaging light.

Because of the proliferation of safety requirements now requiring greater numbers of employees to wear safety eyewear, cost, ease of replacement of the lenses, the ability to accommodate prescription lenses, and fashion have now become prime concerns for customers of these safety products.

DETAILED DESCRIPTION

Referring now to the Figures for the purpose of illustration, it is to be understood that standard components or features that are within the purview of an artisan of ordinary skill and do not contribute to the understanding of the various exemplary embodiments are omitted from the Figures to enhance clarity.

FIG. 1 illustrates an exemplary safety eyewear 10 that includes a removable lens carrier 12, a lens 14, a frame 16, and a removable prescription insert 18. The removable lens carrier 12 is removably attached to the frame 16 and the removable prescription insert 18 is also removably attached to the frame 16. The safety eyewear 10 can also include a strap 20 is used to secure the safety eyewear 10 to the user.

In one embodiment, the frame 16 is made of a semi-flexible material, which provides a connection point for removable lens carrier 12. The frame 16 and the removable lens carrier 12 may connect to one another using a variety of attachment mechanisms including, but not limited to, a tongue and groove junction, a male and female flange connection, a latch, or the like. In one embodiment, the frame 16 and the removable lens carrier 12 may form an airtight seal. The frame 16 may also include a face seal gasket 22 that provides a seal between the frame 16 and the users face. The removable prescription inset 18 may be attached to or detached from the frame 16 when the removable lens carrier 12 is not attached to the frame 16.

The removable lens carrier 12 is removably attached to the frame 16 and permanently attached to the lens 14. The lens 14 may be provided with a variety of tints and coatings. The removable lens carrier 12 and the lens 14 may have a variety of shapes and sizes that are each specifically designed and intended for a particular use or a particular environment. The removable lens carrier 12 is designed such that a user may detach it from the frame 16 while the user is wearing the frame 16. For example, a user may be able to change the type of lens used without having to completely remove the safety eyewear 10. The removable lens carrier 12 allows the user to use a single safety eyewear in a variety of different environments and for a variety of different uses.

In exemplary embodiments, the removable lens carrier 12 may completely encase the lens 14 or may only partially encase the lens 14. In one embodiment, the removable lens carrier 12 may not cover, or attach to, a bottom portion of the lens 14, which may increases the available viewing angle to the user. For example, traditional safety goggles include a thick frame on the bottom portion of the safety goggles that may obstruct the user's field of vision. The use of a removable lens carrier 12 that does not cover, or is attached to, the bottom portion of the lens 14 provides the user with an unobstructed field of vision. Additionally, the frame 16 may also have a reduced thickness on the bottom portion of the safety eyewear 10 to provide an increased field of vision to the user.

Referring now to FIG. 2, another exemplary safety eyewear 100 that includes a removable lens carrier 112, a lens 114, and a frame 116 is illustrated. The safety eyewear 100 is designed to provide an unobstructed field of vision to its user. Accordingly, the frame 116 extends from a lower portion of one side of the safety eyewear 100 across the top of the safety eyewear 100 to the lower portion of the opposite side of the safety eyewear 100. In addition the removable lens carrier 112 only covers the sides and upper portion of the lens 114 thereby providing the user with an unobstructed filed of vision.
