Shermaine Wong –
What are the differences between the Positive and Negative lenses?
Imran Hanafiah –
Thank you for your question, Shermaine! The main difference between the Positive and Negative lenses for the Mares Star SF Mask is the way they correct your underwater vision. The Positive lenses are designed to partially correct nearsightedness, making objects appear clearer and more defined underwater. The Negative lenses, on the other hand, are designed to partially correct farsightedness. This means that with the Negative lenses, you’ll be able to see further underwater than with the Positive lenses. However, if you have perfect vision, you may not notice a difference. We hope this helps, and please let us know if you have any further questions!

How does the Mares Optical lens for Star SF Mask – Negative – Left perform in extremely cold water?
Junhao Lo –
Thank you for your review, Michelle. The Mares Optical lens for Star SF Mask – Negative – Left is designed to provide excellent optical clarity in a wide range of conditions. However, we couldn’t find any specific information on its performance in extremely cold water. The Star SF mask is known for its ability to perform well in various conditions, but its performance in cold water would depend on the specific conditions. We would recommend using a mask anti-fogging treatment or other solutions to help minimize fogging in cold water. If you have any further questions or concerns, please feel free to ask.

Eleanor Wong –
I recently purchased this Mares Optical lens and I must say it’s a game-changer. The image quality is crystal clear, and it’s incredibly easy to install. I’ve been using it for a few weeks now, and I haven’t encountered any issues. The only thing I wish they had included was a carrying case.
Justin Lim –
I’m a bit disappointed that the lens doesn’t come with a warranty. Despite the high price point, I expected a certain level of protection for the investment.
Emily Chen –
Can anyone confirm if this lens is designed for use in low-light conditions?
Junhao Lo –
Thank you for your question, Emily! Our Mares Optical lens for Star SF Mask – Negative – Left is designed to provide clear and precise vision in various conditions. However, regarding low-light conditions specifically, this lens is more suited for improving image quality in bright environments rather than low-light conditions. If you’re looking for a lens for low-light conditions, we may have other options available that might better suit your needs. Please let us know if you’d like to explore those further.
Bernard Tan –
Honestly, I was expecting a bit more from this product. The image quality is good, but it takes some time to get used to the new lens, especially during dives in low light conditions.
Kevin Lee –
Does anyone know if this lens is compatible with prescription masks?

How does this lens compare to the right lens in terms of image quality?
Imran Hanafiah –
Thank you for your question, Rachel. Both the left and right lenses for our Mares Optical lens for Star SF Mask are designed to provide exceptional image quality. However, since you’re looking for a comparison, I can tell you that our testing has shown minimal differences between the two lenses, with the left and right lenses offering identical optical clarity. This is because both lenses are manufactured using the same high-quality glass and undergo rigorous quality control checks. Would you like to know more about the materials or manufacturing process of our lenses?
