Recently i purchased 2 specs having bluecut lenses . I don’t hink those glasses are bluecut . I feel like they are just Normal anti glare lenses.
i know how to check bluecut lens with a uv light but i don’t have one , so if any who purchased bluecut lens from coolwinks and checked for its authenticity can give their views
