Astigmatism: An eye condition caused by a curvature of the front surface of the lens. It can lead to stretched vision causing headaches and eyestrain.

Blue Light Filter: Lens technology that protects your eyes from harmful blue light by blocking UV rays emitted from digital devices.
Bridge: The section of the frame that goes across the nose.
Convergence: When the eyes move inwards towards each other.
Cornea: Allows light to enter the eye through the transparent front portion covering the iris, pupil and anterior chamber.

Farsightedness: Also known as hyperopia, causing near objects to appear blurry.
Floaters: Undissolved vitreous humor that causes lines in front of the eye.
