A wearable training apparatus has a vision-control assembly and a head-mounting assembly coupled to the vision-control assembly. The vision-control assembly has a see-through area corresponding to a central portion of the human field of vision (FOV), and a vision-blocking area for blocking the human peripheral FOV except the central portion thereof. The wearable training apparatus may be in the form of a pair of eyeglasses with lenses provided with reduced FOV or alternatively, may be in the form of a goggle with reduced FOV. A training system may comprise one or more wearable training apparatus, one or more imaging devices for recording images and/or video streams of the performance of users wearing the training apparatuses, and one or more computing devices for playing back and analyzing the recorded images and/or video streams.

Virtual reality apparatus, and various methods therefor.

Virtual reality apparatus, and various methods therefor.

Methods for treating Blepharitis, Meibomian Gland Dysfunction and Dry Eye Syndrome include thermal massage, thermal debridement, and thermal expression. Particular embodiments include use of handheld devices that provide the thermal therapy to tissue by contacting a surface heated with thermal energy to a patient's tissue. Thermal energy can be continuously provided during operation. In particular embodiments, a handheld device comprises a base assembly operatively connected to a removeable thermal energy applicator. A wide range of thermal applicators may be connected to the base assembly to provide different treatments, including heat application, debridement, and expression of the treated tissue or gland.
