What is the "Blue color light "of digital devises which is said to
be the cause of glares, flickers: the shorter the wave length of the light is the more energy it has.

2. Progressive Multifocal Lens
♦. Progressive spectacle lenses are corrective lenses used in
eyeglasses to correct presbyopia and other disorders of
accommodation.
♦. The lens location of the correct addition power for the
viewing distance usually only requires small adjustments to head
position, because near vision tasks such as reading are usually low
in the visual field and distant objects higher in the visual field.

(image-jumps) in the visual field created by the majority of
bifocal and trifocal lenses and are more cosmetically
attractive.
