The principle ofoperation is based on the alternate placing the different dioptres lens to aneye. In such a way the eye-muscle swinging takes place. The “swinging” method useallows training the change of the eyes focusing during the objects visualperception which are situated in the different distances away and to assure thesteady normal lasting eye refringence. By this any shortsightedness and longsightednessexposures are eliminated. The squint lens use corrects the cross-eye.Thedevice’s existing analoguesdid not get the widespreaddistribution because of their large dimensions andconsiderable materialcapacity.Alongside with this the useof the similar devices is possible only in the specially dedicated hospitalrooms.The main principleof OAED is a new approach to the ophthalmological equipment for the eye sightswinging. The OAED device is compact and stylish what gives the possibility touse it in the everyday life: at home, in transport, at work, at the rest. Itscompactness is achieved by means of a unique lens position structural design:12 lens are located in a closed chain, which is of the Mobius band form.The lens changein the loop is caused automatically by a servodrive every minute. The drive ispowered by the kinetic energy. The battery charges during the motion.The device givesthe possibility to train the eye-muscle, correcting the longsightedness or shortsightednessin any conditions, it is also compacted and fits in a pocket, and it is possibleto set a center-to-center distance on this device individually for a specificpatient.
