Maria Leong –
I’ve had minor issues with the Mares Optical Lens for Rover masks, but overall I am satisfied. The minor complaint I have is when I wore my goggles underwater, the lens would change its view but would take a few seconds to return to the normal view after I removed the mask from the water.
Astrid Lee –
Good fit, perfect for my diving needs. What are the differences between this negative lens and the positive one?
Imran Hanafiah –
Thank you for your review, Astrid. The main difference between our negative lens and positive lens is the curvature of the lens. A negative lens is designed to spread light, creating a wider field of view, whereas a positive lens is designed to converge light, providing a more focused view. This can be beneficial for certain diving conditions and personal preferences. I’m glad this lens fits your needs!
Yasmin Tan –

Isabel Wong –
I’m curious about the impact of the negative lens on the overall image quality. Does it still manage to maintain sharpness under the constant changes I go underwater?
Junhao Lo –
Thank you for your question, Isabel. The Negative lens is designed to reduce glare and improve visibility in underwater environments. Our lenses are made with high-quality materials that maintain their sharpness even in changing light conditions.
