Hi,
Most masks have an adjustableT shaped piece that rests against the forehead. Moving the forehead pads further away from your forehead lets the angle of the mask sit closer at the top, forming a tighter seal. minimizing eye leaks. Another thing many new users do is overtighten the lower straps, which also tilts the eye area of the mask away from the face.
Many brands of masks have a size "shallow" cushion. The V at the top of the mask for the nose bridge is not as deep, they recommend it for people with low nose bridges, as in asian faces. Depending on brand, you may not have to replace the whole mask, but can just buy the cushion replacement.
As for triangular nasal masks, I think the best sealing mask on the market is the Activa. It inflates and molds to the shape of your face, and doesn't loose its seal easily with movement.
You don't mention your sleeping position, but sometimes the mask seal is compromised by pressure against a bed pillow.
Another culprit can be allowing the full weight of the air hose to pull against the mask. Supporting part of the hose wt. with clips or eleastic bands/hooks can help reduce tugging at the mask from the hose.
