The DefenderShield Signature Series are blue light blocking glasses offered with two lens choices: amber lenses that filter about 50% of blue light for daytime use, and orange lenses that filter about 99% for evening use. They are aimed at people who spend long hours in front of screens and want to reduce digital eye strain or protect their sleep. Compared with basic blue light glasses, the two-lens approach lets you match the filter strength to the time of day. Owners rate them highly, though some note the orange tint is very strong and the frames feel less premium than expected.

Reviewers give the glasses high marks for comfort and effectiveness, especially the orange lens for evening use. The main complaints are the strong color shift with the orange lens and a somewhat flimsy feel to the frames.
These blue light blocking glasses place a filtering lens between your eyes and a screen. They come with one of two lens options. The amber lens filters 50% of blue light and is designed for daytime and all-day use. The orange lens filters 99% of blue light and is designed for nighttime use.
The amber lens has a slight tint that looks close to clear glasses and keeps on-screen colors close to their original appearance. It suits office work, browsing, video calls and general screen time in daylight. The orange lens has a deeper tint that noticeably shifts color perception. It is meant for evening screen sessions, gaming, and use within 2 to 3 hours before bed.
The frames are made from acetate, a plant-derived plastic that is lightweight, durable and gentle on skin. The rectangle shape has clear top and bottom edge accents and is unisex with a standard fit. The lenses are CR-39, a shatterproof optical plastic used in prescription eyewear. They have anti-glare, anti-smudge and anti-fatigue coatings.
