Lang Stereotest I-R

The Lang Stereotest I-R is suitable for binocular diagnosis and screening of stereo vision disorders in young children of pre-verbal age. This test is the revised and improved version of the Lang Stereotest I named after the Swiss ophthalmologist Joseph Lang, as the optical and printing quality has been improved. In addition, this version has no monocular clues when used correctly.


The Random Dot test card is provided with three random dot stereo objects in different disparities. The test is performed with a reading distance of approx. 30 - 40 cm, without the additional use of glasses to separate the visual impressions. This allows the child's eye movements to be observed without restriction.

Busy bone
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves these!! Great busy bone! And they can hold it with her paws really well. It does kill your foot if you step on it barefoot in the middle of the night. This is a picture of the bone after 7months.

My Dog Loves this!
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves her Nubbies! My Dog chews her Nubbie every morning after she has her breakfast. She sometimes wants my husband or I to hold it for her while she chews on it. I think it is really good for her teeth and gums. These last a few months for our dog who chews it every morning. After a few months the edges get a little rough from all the chewing so I throw it out and replace with a new one. These are very reasonably priced, so I always have a fresh one ready to go. She gets very excited when we get a new one out of the package..

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

Great toy to relieve stress in a dog.
Color: Orange
He actually cares FOR this toy. I think he thinks its alive. I put it in his Kong weeble wobble thing because that thing actually is indestructible, thinking he'd be able to play with it but not be able to tear it up and he started yelping like he was hurt. I do expect him at some point to tear this thing up if he gets bored with it. He's a shredder and the material looks shred-able. But right now he loves this thing. First toy he takes to bed with him. ;)
