♦ You can choose between HD Glasses and SD Glasses.
♦ The SD Glasses have a “heavy” plastic Frame and the HD glasses have a more “light” frame.
♦ The SD glasses have on both sides prism glasses and make a strong 3D Effect.
♦ The HD 3D glasses have only on one side a prism glass and make a light but more clear effect.
♥ I prefer the HD one because you can see more details and its more comfortable for your eyes.
