Semi-finished 1.67 Blue Cut UC/HC/HMC Lens

A 1.67 blue-block semifinished lens would be lightweight, thinner than traditional lenses (even for stronger prescriptions), and offer protection against blue light exposure. This makes it a great option for individuals who spend a lot of time in front of screens and want to avoid the discomfort of heavy, thick lenses. It’s also good for anyone looking for modern eyewear with a combination of style and eye health benefits.

1. 1.67 Index
● Advantage: A 1.67 index is a high-index material, meaning the lenses are thinner and lighter than standard lenses (which are often made from materials with a lower refractive index, such as 1.49 or 1.56 or 1.61). This makes them especially useful for people with stronger prescriptions, where a higher index helps keep the lenses from becoming too thick or bulky.

2. Blue Block (Blue Light Filter)
● Blue light filtering lenses are designed to reduce the amount of blue light that reaches your eyes. Blue light, emitted from screens and LED lights, can contribute to eye strain, fatigue, and interfere with sleep patterns.
● Advantage: Reduces digital eye strain, potentially improves sleep quality by blocking blue light exposure at night, and can decrease the risk of long-term eye health issues like macular degeneration.

3. Semifinished Lens
● A semifinished lens is a lens that has been pre-milled to a basic shape but is not yet ready for full use. The lens will still require further shaping and finishing to fit the individual’s prescription and frame.
● Advantage: Allows for faster production times and flexibility in creating custom lenses for different frame styles and prescriptions. It also gives opticians the ability to adjust the lens for specific vision needs.
