What is the primary purpose of decreasing pantoscopic tilt in eyeglasses?

To improve peripheral vision
To reduce glare from overhead lighting
To enhance cosmetic appearance
To effectively raise the bifocal seg height

The correct answer is: To effectively raise the bifocal seg height

Decreasing pantoscopic tilt is done in eyeglasses to effectively raise the bifocal segment height. This helps to provide clear vision for those who need both distance and close-up correction. It is not done for the purpose of improving peripheral vision, reducing glare, or enhancing cosmetic appearance. These are not the primary reasons for decreasing pantoscopic tilt.
