SOME MORE HINTS
— Everybody knows that vision changes with age, accompanied by rapid reduction in visual performance.Yet there are many people who have not yet corrected their eyesight for their everyday work.
— Remember that requirements for corrective lenses for a VDU or computer screen are different from those for reading a paper copy. A display screen requires a longer viewing distance (more than 50 cm) and a viewing angle that cannot be reached by bifocal lenses.
— Regularly clean your glasses, screen and anti-glare
filter.
