There are several models of frames, namely, World Champion 1, World Champion 3, World Champion 4, Olympic Champion, Olympic Offset / Archery Champion, and the SuperOlympic Champion.
World 1 is our entry level Champion glasses, the frame is made of aluminum alloy. Its lens holder can be adjusted up and down, moved along the frame left and right, be turned left or right on a vertical axis, and offers tilt adjustment on a horizontal axis just above the lens holder ( not along the frame like other makes of shooting glasses, which is high above the lens holder and affects the lens-to-eye distance ).
World 3 offers height-adjustable nose-piece stem and silicone nose-pad instead of plastic ( as on World 1 ). It combines comfort, convenience, and versatility at a very affordable price. Other features are same as the World 1.
World 4 features an improved nosepiece stem which can be adjusted by turning a knob on the top. This makes adjustment while wearing possible.
All the above models can be fitted with the optional sides with adjustable elastic band for a more comfortable and personal fit.
Olympic is the most popular model with all the sophisticated designs for maximum flexibility in adjustments and comfort. The frame is made of titanium, offering light-weight and strength. Micro adjustment rings allow adjustments while wearing the glasses. Spring loaded sides offer snug fit.
Olympic Offset / Archery has a unique yet useful design. On loosening a set screw the nosepiece stem can be rotated along the top frame on the front either left or right so that the vertical part of the nosepiece stem is out of the way of the nose thus allowing the positioning of the lens-holder directly in front of the shooter's nose. This may be required when the shooter is employing an extreme aiming position often found in the standing position in rifle 3P and in archery.
SuperOlympic is the latest technological marvel in shooting glasses. With a number of ingeniously devised micrometers the shooter is able to, while wearing the glasses, made fine adjustments to the aiming lens without any tools. Turning knobs is all it takes. Adjustments include left/right shift, left/right rotation, up/down shift, and front/back tilt. This proves to be an invaluable feature while on the firing line during a match, and certain environmental element calls for changes in your glasses settings.
Champion shooting glasses is the choice of numerous world class shooters - perhaps for good reasons. The Olympic Champion series of shooting glasses are precision instruments and, as such, require careful calibration during set up to ensure perfect results.
They are not cheap, so aren't Ferraris and Lamborghinis. However, you want them when performance counts.
Lens holders come in three sizes: 42 mm, 32 mm, and 25 mm. 42 mm is recommended for pistol shooters because it offers maximum eye coverage. 25 mm is mostly used by rifle shooters. 32 mm is an alternate choice between the other two. For trap and skeet shooters there are special lens holders that are not round but oblong, providing a wider field of view for the moving target.
The new SuperOlympic Champion uses its own range of lens-holders which have a straight stem at the top instead of an "L" shape stem.
Champion designed a unique two-in-one shield called the combi-shield. It actually is two shields in one. It consists of a grey shield in front of a white shield, each connected to the main stem via its own axis. The shooter can lift up the grey shield and just use the white shield, or lower the grey shield in front of the white one for maximum light blocking. It can be fitted for the left side or the right side by simply flipping the sides in the opposite direction.
The current ISSF rules limits the front eye-shields to a maximum width of 3 cm ( there is no limit on its vertical dimension ), and no side flaps are allowed ( exceeds the 3 cm limit ). A separate ISSF shield is available for that purpose.
The ISSF compliant side shields have a depth of 4 cm, and comes in either gray or white for personal preference.
With the introduction of the purple filter, there are now 6 different colour filters to choose from. The use of filters is a very subjective choice, but there are some general guidelines for the novice shooter to follow:
- latest addition to the Champion coloured filter line-up, the purple filter provides cool filtering of warm spectrum light such as indoor incandescent lights or strong direct sunlight outdoors, greatly clarifying target image.
- used in dull weather, cloudy or heavy overcast days, it increases contrast on the target
- for bright sunny days, it cuts down the glare on the target
- a cross between yellow and grey, it improves contrast and cuts down glare
- a versatile colour that seems to suit every lighting condition and improves visual acuity
- by rotating two filters at different angles one can achieve varying degrees of darkness to block out extra light
By adjusting the size of the aperture in the iris one can control the depth of field and achieve certain sharpness effects on the sights. Rifle shooters have their iris on the rear sight, pistol shooters have to put the iris on the glasses ( behind the lens and in front of the eye ), but they do a similar job. Shooters with astigmatism usually find iris can help achieve a better sight picture whereas lens alone, even with proper prescription, may not be totally satisfactory.
