Semi-finished 1.61 Blue Block UC/HC/HMC Lens

1. 1.61 Index Material:
● Thinner and Lighter: The 1.61 index lenses are thinner than standard 1.49/ 1.56 lenses, making them ideal for people with stronger prescriptions. This material reduces the thickness and weight of the lens, offering greater comfort and aesthetics.
● Better Aesthetics: With a higher index of refraction, these lenses provide a more attractive appearance, particularly for those with high prescriptions, where lenses can otherwise become bulky.

2. Blue Block (Blue Light Filtering):
● Reduces Blue Light Exposure: Blue block lenses are designed to filter out a portion of the blue light emitted by digital screens (smartphones, computers, TVs), artificial lighting, and sunlight. This can help reduce eye strain, fatigue, and discomfort from prolonged screen use.
● Improved Sleep Quality: By blocking blue light, these lenses may help in reducing disruption to circadian rhythms, which can improve sleep quality, especially if you use screens at night.
● Prevention of Long-Term Eye Damage: While the research is still ongoing, some studies suggest that prolonged exposure to blue light could contribute to retinal damage over time. Blue-block lenses can help mitigate potential risks.

3. Semifinished Lens:
● Customization: Semifinished lenses are partially processed lenses, often supplied to optical labs where they are further shaped to the prescription and fitted to the frame. This makes them versatile and customizable for different prescriptions and frame styles.
● Efficient Production: Since the lenses are not fully finished, this allows for faster production times and can be adapted more easily to varying prescriptions.
