Oskav is the name of a new UK-based brand specialized in making passive 3D movie glasses with style and at an affordable price. The Oskav 3D designer glasses offer the perfect combination of classic style, sunglasses-quality frames and high density circular polarized lenses at a price that everyone can easily afford (£19.99 UK pounds or about $31 USD). Currently there are three different models available with worldwide shipping (free shipping in UK) that are intended for use by adults, but a specially designed range for children is also expected to be released soon. The designer 3D movie glasses made by Oskav are intended to be used in movie theaters using RealD 3D projection technology, but they are also compatible with a lot of passive 3D-capable HDTVs and could also work with some passive 3D computer monitors as well…

I’ve already mentioned here that I like more the classic designs for 3D glasses and the Oskav 3D glasses’ style is just ideal for every one else with such preferences, but it is not all about the design. The passive 3D glasses made by Oskav have very good technical specifications as well that ensure optimum quality. The use of thicker polarizing filters with 10 composite layers constructing each of the lenses means that you get no image distortion and the lenses are more durable. The optical characteristics of the lenses have been optimized to better light transmittance and to minimize the negative effects such as crosstalk, so that you can get the best experience watching 3D movies. And you can also soon expect a review of the Oskav 3D glasses…

LG Electronics its newest collection of 3D glasses, including a pair designed by the eyewear designer Alain Mikli, that will be introduced in the first quarter of 2012. The new line of passive 3D glasses will offer more stylish looking products – the F310, the clip-on F320 and the Alain Mikli F360 – are lighter and more comfortable to wear on one hand, and on the other the new design also offers features such as curved lenses and clean frame structure. So it seems that LG is apparently starting to move the focus from offering only cheaper passive 3D glasses, to offering affordable and good looking 3D glasses for its range of Cinema 3D TV passive 3D-capable television sets . Because the currently available range of passive 3D glasses that LG offers are not only cheap in terms of price, but also look cheap in terms of design and production and are not very sturdy and durable. Of course the new line of better-looking passive 3D glasses introduced should not be much more expensive than what the company already offers on the market, although prices have not yet been revealed…

The new LG F310 passive 3D glasses are characterized by a distinctive design that combines soft lines within a slim frame. Unlike many previous 3D glasses, the lenses have been curved to better accommodate the shape of the user’s face, as well as to improve the overall 3D viewing experience. The F310 glasses’ weight about 13.5 grams, making it about 20 percent lighter than LG’s previous design. The new LG F320 will be clip-on 3D glasses that are going to be even lighter at a weight of just about 5.5 grams, but these are of course designed to be worn over a pair of prescription glasses, so they need to be lighter. And the third new model has been developed in collaboration with Alain Mikli, the LG F360′s half-rim frame design is sportier and has a weight of only 16 grams. The lenses of the LG F360 passive 3D glasses have been curved and cover most of the user’s face, for a deeper immersion and better stereoscopic 3D experience. Besides being compatible with the Cinema 3D TV range of 3D-capable TV sets from LG, the new passive 3D glasses are also compatible with some 3D movie theaters that use RealD projection technology, as well as other compatible passive 3D displays.

We know that with 3D vision 2 active shutter glasses Nvidia has increased the size of the lenses used by 20%, but what this means in terms of the increase of the width and height of the lenses? On the photo above you can see 3D Vision 2 (left) compared to MonsterVision Max 3D glasses (right) with the Monster glasses being the ones with the biggest lenses I’ve seems so far among active shutter glasses. On the photo you can see that Nvidia’s new 3D glasses are almost catching up to the Monster’s 3D glasses in terms of size, so here is the width and height of the visible size of the lenses between these three 3D glasses, measuring roughly the size with the minimum and maximum height and width:

3D Vision:
Lens height – 26-32 mm
Lens width – 36-54 mm

3D Vision 2:
Lens height – 30-35 mm
Lens width – 36-58 mm

MonsterVision Max 3D:
Lens height – 30-41mm
Lens width – 38-58 mm

And since the lenses of the glasses are not with an exact rectangular size it is harder to confirm these 20% size increase between the first and second generation 3D Vision, but let us believe Nvidia on this one. I was personally more interested by the fact that the lenses of the new 3D Vision 2 glasses have roughly the same width as Monster’s 3D glasses, although they are not as high. This is a good news, considering the fact that all 3D Vision ready 3D LCD monitors are wide aspect ones, but with 3D projectors there are still quite a lot of models with 4:3 or 16:10 aspect ratio and for these bigger not only in width, but also in height lenses can be considered better.

And now for what is the weight of the old and new 3D Vision shutter glasses. As you can see from the photos, the 3D Vision glasses (on top) are a bit lighter at about 51 grams and the new 3D Vision 2 glasses (on the bottom) have a bit of extra weight for a total of about 56.2 grams. Not much of a difference, but the weight is increased a bit. According to Nvidia the new glasses should be able to provide you with up to 60 hours of usage on a single charge, the same amount of time you get with the revised version of the old 3D Vision glasses. As I’ve already mentioned in a previous post the new 3D Vision 2 glasses use a built-in 70 mAh lithium-ion rechargeable battery. And just as a comparison some of the 3D HDTV manufacturers have managed to reduce the weight of their active shutter 3D glasses to less than 30 grams (with less usage time on a single charge however), so there is more to be desired in terms of weight reduction for the next generation… ;)
