Bifocal Corrective Lenses (RX)

Franklin bifocal lenses for a diving mask are an optical solution that integrates two different corrective areas in one lens. The upper part of the lens provides clear distant vision, which is ideal for observing underwater landscapes, while the lower part allows for clear close-up vision, making it easier to read diving instruments. This allows divers to enjoy the full spectrum of vision underwater, without having to change masks or use additional corrective lenses.

Choose these lenses if you wear bifocals or two pairs of glasses every day. Different values ​​of lenses for sharp vision of objects located near and far.

Franklin bifocal lenses are a classic optical solution that consists of two separate correction zones in one lens. The upper part of the lens is designed for distance vision, allowing you to see objects at a distance clearly. The lower part of the lens is designed for near vision, allowing you to read, write, and perform other activities that require sharp close-ups.
Key Features of Franklin Bifocal Lenses:
- Dual Zone: Two separate viewing zones - one for distance, the other for near.
- Visible dividing line: A clear line separating the two correction zones.
- Functionality: Ease of adaptation and use in everyday situations.
- Durability: High-quality materials ensure long-term use.
Franklin bifocal lenses are a popular choice among people who need vision correction at various distances and appreciate the simplicity and effectiveness of this solution.

Diving Mask Lens Material

Index 1.5 mineral lenses
Lenses with an index of 1.5 are standard optical lenses that have a refractive index of 1.5. This index describes how light passes through the lens compared to air.
Properties:
- Thickness: Lenses with this index are relatively thicker than those with higher indices.
- Weight: Due to the greater thickness, they are slightly heavier.
- Light transmission: They provide very good image quality, although they are thicker than lenses made of materials with a higher refractive index.
Destiny:
Lenses suitable for those with minor vision impairments, ranging from -4.00 to +4.00 diopters. They are a popular choice due to their affordability, durability and wide availability. Index 1.5 lenses are a solid solution for those looking for reliable and standard vision correction options.

Mineral Lenses with Index 1.6
Mineral (glass) lenses with an index of 1.6 are characterized by a higher refractive index compared to standard lenses. Made of high-quality optical glass, they are thinner and lighter, which provides greater comfort of wearing and an aesthetic appearance.
Properties:
- Thin and light: Thanks to their higher refractive index, 1.6 mineral lenses are thinner compared to those with a lower index, and also lighter, which increases wearing comfort.
- Durability: Mineral lenses are less susceptible to scratches than their plastic counterparts, making them more durable.
- Aesthetics: Due to the thinness of the material, the lenses look more aesthetically pleasing in frames, which is especially important for stronger visual impairments.
Destiny :
Mineral lenses with an index of 1.6 are especially recommended for people with higher visual impairments, above -4.00 and +4.00 diopters. They are an ideal choice for those looking for a combination of comfort, high durability and better appearance. These lenses are an excellent solution for users with high optical requirements, combining the strength of glass with modern optical properties.

Mineral Lenses with Index 1.7
Mineral (glass) lenses with a refractive index of 1.7 have advanced optical properties, making them thinner and lighter than lenses with lower indices. Thanks to the use of high-quality optical glass, these lenses provide excellent clarity and comfort.
Properties:
- Thin and light: 1.7 index mineral lenses are significantly thinner and lighter, providing greater comfort and aesthetic appearance.
- Durability: The optical glass used in these lenses is more scratch-resistant compared to plastic lenses, which increases their durability.
- Aesthetics: Thanks to their reduced thickness, the lenses look more aesthetically pleasing when worn with glasses, even with higher prescriptions.
Destiny:
Lenses with an index of 1.7 are ideal for people with higher visual impairments, usually above -6.00 diopters, and who value comfort and aesthetics. Due to their optical properties, they provide excellent quality of vision, while maintaining the lightness and thinness of the lenses.
These lenses are an excellent choice for demanding users who need an effective and comfortable optical solution without compromise.
