How much blue light do Zeiss lenses block?
ZEISS BlueGuard® Lenses provide sunglass-level UV protection and block up to 40 %1 of potentially harmful and irritating blue light.
What is Zeiss DuraVision BlueProtect?
ZEISS DuraVision BlueProtect is a special lens coating for people who spend a lot of their time indoors and are exposed to the potentially harmful blue light emitted by LEDs, televisions, computer screens or tablets and who are concerned about their exposure.
Do Zeiss lenses block blue light?
DuraVision® BlueProtect by ZEISS, a blue light blocking coating for lenses which partially filters blue-violet light; ideal for indoor activities. PhotoFusion by ZEISS is a self-tinting lens that blocks different intensities of blue-violet light, and also offers sunglass-level UV protection.
Who makes intraocular lenses?
The global intraocular lenses market is dominated by five major players namely, Alcon, Inc. (US), Bausch + Lomb (US), Johnson & Johnson Vision Care (US), Carl Zeiss Meditec (Germany), and HOYA Corporation (Japan); and together these key players accounted for a share of about 67% in 2016.
What is Zeiss SmartLife?
ZEISS SmartLife is a complete premium lens portfolio for consumers of all ages. In addition to offering tailor-made corrective solutions, the lenses are designed for modern, dynamic, connected and on-the-move lifestyles and the associated visual behavior.
What is Zeiss PhotoFusion?
Photochromic lenses that change from clear-to-dark and back. ZEISS PhotoFusion X Lenses adapt quickly to changing light conditions. They darken very fast and fade back to clear up to 4.5 times faster than the most common photochromic brand’s latest generation grey1.
What is DuraVision platinum?
ZEISS DuraVision Platinum is made up of nine ultra-thin layers, an integrated system of coating layers densely packed using ion-assisted deposition results in a lens surface that is three times harder than the previous generation of ZEISS AR lenses.
Who manufactures cataract lenses?
Alcon, Inc.
The global intraocular lenses market is dominated by five major players namely, Alcon, Inc. (US), Bausch + Lomb (US), Johnson & Johnson Vision Care (US), Carl Zeiss Meditec (Germany), and HOYA Corporation (Japan); and together these key players accounted for a share of about 67% in 2016.
What material are intraocular lenses made out of?
silicone
Most IOLs are created from silicone or acrylic. They are then coated with a special material that help to protect your eyes from the harmful ultraviolet rays emitted by the sun. It is important to ensure that you choose the best IOL for your individual needs. Dr.
What is blue light filtering IOL?
The manufacturers of IOLs have now extended the concept of filtering radiation to include short-wavelength blue light (400–500 nm) from the visible spectrum. Blue-light filtering IOLs attenuate wavelengths up to 500 nm.
What is the difference between blue blocking and Violet blocking IOLs?
Violet blocking IOLs reduce scotopic sensitivity loss to 7% but provide roughly the same acute UV‐blue phototoxicity protection as blue blocking IOLs. Blue blocking IOLs provide 23% more melanopsin photoreception than a 53 year old lens but 18% less sensitivity than a conventional UV only blocking IOL.
Are blue-blocking intraocular lenses useful in cataract surgery?
Purpose of review: Ultraviolet-blocking intraocular lenses (IOLs) are used routinely in cataract surgery and are widely accepted. Blue-blocking IOLs, however, have been much debated since their inception.
Do blue-light filtering IOLs affect scotopic vision?
The potential effects of blue-light filtering IOLs on scotopic vision can be examined in terms of transmission of light at 507 nm as this is the wavelength which maximally activates rod cells. A child’s crystalline lens transmits 90 % at 507 nm and an adult lens 60 %.
