Sega Master System 3D glasses

I recently obtained sega 3D glasses for Master System but in my opinion glasses does not work correctly.

When I start any non 3D game I have visible picture on left eye but partially dimmed picture on right eye (left part on right eye is more visible than right part of right eye). Is this normal ? Probably picture should be dimmed almost completly on right eye exactly the same on whole right eye field.

I started Blade Eagle 3D. Title looks ok (eagle is clearly deeper than logo) but in game moving ship up and low with button produces 2 pictures of ship instead feelling of going up and doing down not too mention game play area when I also does not feel deepth.
