Lens Designs Help

Traditional design lenses are your everyday conventional lenses that are made using a standard base curve and a generalized prescription model. They don’t account for individual visual behavior, frame shape, or how the lenses sit on your face. While they can still provide good vision correction, they often lack the sharpness, comfort, and customization of more advanced digital or freeform lenses. These lenses are best suited for basic prescriptions and are generally more affordable, but may not deliver optimal performance in all lighting conditions or for all users.

 

Digital / Freeform key features:

• Digital lenses allow for complex prescriptions and individualized lens designs. This customization can address optical aberrations, improve peripheral vision, and provide a wider and clearer field of view.
• Digital lenses can be designed to be flatter and thinner, making them more aesthetically pleasing and comfortable, especially for individuals with higher prescriptions.
• Digital lenses are particularly effective for progressive lenses, where a smooth transition between distance, intermediate, and near vision is crucial.

 

Digital lenses may be made digitally on both the back and front sides of the lens or only the back side of the lens. Both front and backside digital lenses are referred to as "Freeform" lenses.

 

FreeForm Digital (Both sides)

FreeForm digital lenses apply digital technology to both the front and back surfaces of the lens and offer a higher degree of customization than standard digital backside-only lenses. 

Digital Backside only:

The digital technology is applied to the back surface of the lens, which is the side facing the eye. The front surface of the lens remains conventionally ground.

Reading boost key features:

• Magnification Near Vision
• No visible lines on the lens
• For mild reading powers
• Enhanced Reading Comfort
• Designed for Pre-presbyopia
• Lower cost than progressive lenses

 

Boost power availability:

The powers available for reading boost may vary based on the lens brand.

 

Lens brand	Powers available
Essilor Eyezen	+0.40, +0.60, +0.85, +1.10
ZEISS SmartLife Digital	+0.50, +0.75, +1.00, +1.25
Hoya Sync III	+0.57, +0.95, +1.32

Most lenses are Spheric with a standard conventional design with curvature based on the prescription strength. Aspheric lenses are a type of eyeglass lens designed with varying curvature to achieve a flatter and thinner profile, minimizing the "bug-eye" or "coke-bottle" effect associated with strong prescriptions. These lenses enhance aesthetics, provide improved peripheral vision, reduce image distortion, and offer a lighter weight than traditional spherical lenses. Aspheric lenses are particularly beneficial for individuals with higher prescriptions or astigmatism, providing a more natural appearance and comfortable visual experience. They are functional and contribute to a cosmetically appealing design for eyeglasses.
 

Key features:

• Reduced lens thickness
• Improved aesthetics
• Enhanced peripheral vision
• Minimized image distortion
• Lighter weight

Computer progressive lenses, also known as computer lenses or occupational progressive lenses, are specialized eyeglasses designed to optimize vision for intermediate and close-up distances, specifically for extended computer use. These lenses address the unique visual demands associated with digital devices and the working distances typically encountered during computer work.

Key features:

• Intermediate and near vision correction
• Reduced eye strain
• Wide field of view
• Minimal peripheral distortion
• Adaptation to working posture
• Customization for individual needs

Bifocal & trifocal lenses come in various designs to address different vision needs. The lower part for near vision has a flat or straight top line, creating a visible segment in the lens. Trifocals and Occupational lenses include an additional segment for intermediate vision. Choosing the right design depends on individual preferences and lifestyle.
