The resolution of progressive cheapest eyeglasses lenses with the same luminosity can be analyzed through wearing or photometric topographic maps.

Multi-focus lenses, also known as progressive multi-focus lenses, refer to the organic connection between the far and near light areas of the same lens in a gradual change of refractive power, from far to near, gradually connecting the far and near light areas. Therefore, a single lens can simultaneously have different luminosity requirements for viewing far, medium, and close distances.

Progressive multifocal lenses are divided into three categories: adolescent myopia control childrens eyeglasses lenses, which are used to alleviate visual fatigue and control the speed of myopia development. Adult anti-fatigue lenses are used by close-range and computer users to reduce visual fatigue caused by work. Progressive films for middle-aged and elderly people are used as a pair of glasses for easy vision, far-sightedness, and close-sightedness.

These functional lenses have commonality and are mainly made using the following principles:

Multi-focal lenses: Adding light to the myopic area below the lens increases the positive mirror power, resulting in myopia for the user. Such a design can reduce the use of adjustment during close-range vision for patients. Multi-focus lenses are also designed for different age groups such as kids eyeglasses near me, adults, and middle-aged and elderly people, with different design concepts and uses.

Peripheral high focus design: By changing the peripheral power, the center of the lens is imaged on the macula of the corrected eye, and the peripheral image is also imaged on the retina (anterior) of the corrected eye.

When choosing lenses, it is best to go through a specific functional check and choose the appropriate lens for yourself. Developing good eye habits in daily life and maintaining scientific prevention and control is the key.
