Integrated-lens system for presbyopia

Abstract

The invention relates to an integrated-lens system for presbyopia, which consists of a single-body lens or individual optical lenses, which are coupled to the pane of a pair of closed goggles, integrated goggles or sports goggles and are transparent and unmoulded, occupying a space in the total viewing area of the goggles pane and leaving free of optical correction 100% of the upper area, 100% of the central area and 50% of the lower area of the pane, such that the right and left horizontal viewing angles are also free of optical correction.

Description

[0001] INTEGRATED LENS SYSTEM FOR PRESY EYES

[0002] TECHNICAL FIELD OF THE INVENTION

[0003] The present invention falls within the technical field related to sports and work equipment, more specifically to protective eyewear.

[0004] It is a frameless, independent optical lens or lens system that is installed in protective sports glasses, work glasses, glasses integrated into protective helmets or other glasses of more common structure, with which to improve visualization and correction of tired eyes or presbyopia.

[0005] BACKGROUND OF THE INVENTION

[0006] Protective eyewear devices are known in the prior art for both sports and work applications. These types of protective eyewear are found in sports and work settings, and are also integrated into other items such as protective helmets. However, these glasses are not currently available with lenses or optical correction (frameless) for presbyopia (age-related farsightedness).

[0007] There is a known invention (patented or not) called a Goggle Insert. It is a type of frameless, temple-less frame without lenses and extensions for attaching to the inside of sports glasses or closed-glasses (only for these). These are only suitable for people who wear regular glasses at all times (for both distance and near vision) and significantly interfere with the field and angle of vision of the protective eyewear. There are also frameless lenses joined together by a type of rubber that attaches to the nose pads of cycling glasses. Other lenses are glued directly to the eyewear lenses. Both types occupy the entire space of the eyewear lenses and are still intended for constant, everyday use.

[0008] DESCRIPTION OF THE INVENTION

[0009] The present invention is set forth and characterized in the independent claim, while the dependent claims describe other features thereof.

[0010] The object of the invention is to incorporate a frameless corrective lens or lenses for presbyopia (age-related farsightedness) into a pair of protective glasses, whether integrated into a helmet or not, such as sports or work glasses, or other more common types without optical correction. These lenses are much smaller than the original lens of the protective glasses. They provide different viewing angles depending on the user's needs at any given time, eliminating the need to constantly carry reading glasses. This leaves a large percentage of the original lens of the glasses free for normal vision without optical correction.

[0027] DETAILED EXPLANATION OF THE INVENTION

[0028] The invention consists of incorporating frameless optical lenses (FIG 6A) or a lens (FIG 6B) for correcting presbyopia or age-related farsightedness behind the visor of closed goggles (FIG 1A), (FIG 3), goggles integrated into a helmet (FIG 5A) (FIG 5B), or other goggles of a more common structure (FIG 8). These lenses may be individually, one left and one right for the nasal area (FIG 1A), a single lens (FIG 1B), or a set of two lenses joined by a link (FIG 6A-8). This lens will normally be transparent, easily removable, and replaceable.

[0029] Placement: The lens or lens will be located, fixed to both sides that form the nose arch of the screen or spectacle shell, in magnified view (FIG 9A) mounted on the Closed-Glass shell (FIG 1A) or (FIG 1B), on the Screen-Glass (FIG 4), on the Integrated Goggle (FIG 5A) (FIG 5B) and on a more common goggle (FIG 8).

[0030] Attachment System: The lens(es) (FIG 6) can be installed to the housing or the visor using a built-in clamping system (FIG 6A-8), screws (FIG 6A-7), magnets, or a factory-installed anchoring system in the housing itself, such as a slot into which the lens fits (FIG 9A-2). Different adjustment positions and lens spacing options are available for vision adjustment. Individual optical lenses can also be joined together by the same material, using a support link, plastic connector, rubber, or other means (FIG 6A-8). The lens(es) have different anchoring points and methods (FIG 6A-8 / 7), (FIG 6B-8 / 7 / 9).

[0031] The lenses or lens (FIG 6) can be fused directly to a Display-Glass (FIG 2-1) or an Integrated-Glass (FIG 5A-6) (FIG 5B-6) in their manufacturing process, thus forming a single body.

[0032] Example: In the closed-glass type with lenses or lens already incorporated (FIG 1A or IB) of motorcycle, skier, we avoid including a common glasses inside the same closed-glass, using the lens already incorporated (FIG 7B-2) lowering the gaze when reading the mobile (FIG 7B-21) (FIG 7A-21.2), some type of brochure, document or follow a GPS navigation map we avoid having to stop, park, be looking for reading glasses, take off the motorcycle or ski helmet.

[0033] The discomfort is avoided, especially with a protective helmet (FIG 5), of having to insert ordinary (near-vision) glasses temples through the sides of the helmet, which are tight and uncomfortable, or in this case, putting closed glasses on top of them.

[0034] Wearing regular reading glasses, we wouldn't be able to continue driving, but with the built-in lens or lens there wouldn't be any problem since it leaves the vast majority of the rest of the screen's vision free of correction.

[0035] In the case of closed-face goggles (FIG 1A or IB) for work or helmet with integrated goggles (FIG 5) that require eye protection, it is the same.

[0036] Example: We're working, we need to see more closely what we're doing, and we already have the optical lens or lenses built in. We're going to cut something and we need to measure a wall, board, iron, or window using a tape measure, and if we can see the millimeters on the tape, we don't need to look for our reading glasses. With integrated goggles (FIG 5A or 5B) in protective helmets, which already include the corrective reading lens(es) (FIG 5A-2 or 5B-10), we wouldn't have to: take off the helmet, put on the reading glasses, see what we need to see, take off the reading glasses (since they are only used for "close" vision), and then put the helmet back on.We wouldn't be able to drive or practice that sport or work with them on (common reading glasses) until the next time we have to visualize another situation of this type and have to repeat the previous operation or, as we usually do, lower the reading glasses to the edge of the tip of the nose and look over them at a distance.

[0037] With the lenses or lenses incorporated into these types of glasses mentioned, people with only near vision impairment could easily perform any action that requires these lenses without having to wear their usual glasses (only for near vision) and without disturbing the rest of the visual field (FIG 7A or 7B) of the screen of this type of glasses.

[0038] With the lens(es) already incorporated (FIG 1A or IB) (FIG 5) (FIG 4) (FIG 8), we would only need to move our gaze downwards to see the GPS navigation clearly (FIG 7B-21) (FIG 7A-21.2) and then upwards to see distant objects with normal vision to continue with our work or driving activity through the remaining areas of the screen without optical correction (FIG 7A-22 / 23) (FIG 7B-22 / 23). The upper area of ​​the screen remains 100% free of optical correction (FIG 7A-23).

[0039] (FIG 7B-23), 100% of the middle zone (FIG 7A-22) (FIG 7B-22) and 50% of the lower zone (FIG 7A-21), having vision without optical correction to see far away through a large part of the lower side zone (FIG 7A-21.1) and (FIG 7A-21.3) of the screen (e.g., view of the rearview mirrors of a motorcycle).

[0040] These vision zones apply equally to the

[0041] Integrated glasses are now the most common structure of sports glasses.
