Aspheric Multifocal Magnifying Glass
Normal eye can see near objects because there is a short focus on the retina when the ciliary muscle is contracted and refracting power of the crystalline lens is increased. However, the aging process decreases elasticity of the crystalline lens, which means the refracting power does not increase and consequently a blurring of near vision occurs. As accommodation power decreases as part of presbyopia progress, people need two eye glasses for distance and near vision.  
 
Reading glasses are custom-made for individuals, meaning that they use single vision lenses. As reading glasses are designed for only near vision, they should be taken off to gaze distant objects. Wearing reading glasses for long hours may cause head ache and eye strain. A magnifier is an optical device designed to produce an image of object enlarged to a certain ratio and used by people who are experiencing presbyopia. However, a high magnification ratio can cause optical distortion and reduce clarity, resulting in a disparity between central and peripheral vision and eventually eye fatigue
 
To resolve the weakness of the pre-existing optical devices, Neon Loupe Co has developed aspheric multifocal Magnifying Glasss for the first time in the world using its technology. This aspheric multifocal Magnifying Glass is characterized by its aspheric lens which combines several lenses that have variable refracting power. Therefore, it provides clear sharp texts and images without distortion around the periphery regions of the lens. In particular, this Magnifying Glass does not cause eye strain or headache, making it suitable for those who use their near vision at work or those with low vision. Also, this Magnifying Glass comes with a magnification controller, which can be adjusted according to vision of users in all age groups. In addition, its wide field of view also makes it comfortable to use for extended time.
 
What's an aspheric lens?
Aspheric lens
 Conventional lenses are spherical although they vary depending on type and design. These spherical lenses are widely used because they are easy to produce at a low cost. However, spherical aberration is caused by lens design, and this effect becomes more significant in the periphery of the lens.  
 Aspheric lens was alternatively developed to eliminate spherical aberration. Given its shape that is neither spherical nor cylindrical, it is called aspheric lens. Aspheric lens designs reduce optical distortion and provide more natural view of the world no matter where your gaze is directed.
 
Features of aspheric lenses
-Distortion can be reduced
-The oval shaped peripheral edges provide wider field of view.
-The greater diameter of lens, the greater the decrease in chromatic aberration, distortion and astigmatism.
-Significantly thinner, shallower and lighter than spherical lenses.
 
What is a multifocal lens?
-Multifocal lens
 A multifocal lens comprises an upper distance vision portion and a lower near vision portion of different refractive index. Bifocal or trifocal lenses are not considered aesthetic because boundaries between different refractive powers are easily seen. Also those boundaries cause image jumps in the visual field. Multifocal lenses overcome these disadvantages by utilizing several glasses with different refractive indices without boundaries and provide clear vision in all directions. Consecutive changes in refractive state reduces image jumps in the visual field and dizziness without causing a gap of blurry vision and chromatic aberration.  Boundary-less also makes multifocal lenses aesthetic. However, the intermediate vision portion is narrow, and the near vision portion is smaller, compared with other portions of the lens. Severe flickering sensation occurs as a result of distortion and astigmatism in the lateral blending region, and wearers usually take some time to get used to the lenses.
 
 

  • Advantages of multifocal lenses
  • - Aesthetic without boundaries
  • - Low image jumps in the vision field and low incidence of dizziness
  • - Middle range vision is provided
  • -There is no chromatic aberration.
  • -Consecutive changes in refractive state from distance to near range vision eliminates the gap in blurry vision.
  • Disadvantages of multifocal lenses
  • -Peripheral distortion and flickering sensation occur.
  • -The intermediate vision portion is narrow and unstable, making the use of lenses for extended time difficult.
  • -The near vision is narrow
 
Aspheric Multifocal Magnifying Glass
 
-Aspheric Multifocal Design
-Texts and images remain consistent without being distorted amid changes of diopters when the stand moves in a longitudinal direction.
-Texts and images are clear without being distorted when the stand and object are positioned on a slope.
-Less fatigue during reading or using computers for long hours, compared with reading glasses.
 
-Polycarbonate materials
-Portability is enhanced with compact, lightweight lens of the Magnifying Glass
-Strong shock-resistance reduces the risk of damage.
-Increased durability extends the service life and ensures safety
-The elastic nature of the polycarbonate material protects the lens against damage although the width of the lens is narrow.
 
Treatment reinforced to improve functions of lens
-Hard coating increases abrasion-resistance.
-Multicoating leads to reflection-free clear images
-ITO(EMI) treatment prevents electromagnetic wave and static electricity
-Super hydrophobic treatment reduces contamination and prevents scratching
 
-The size of texts or images can be controlled by adjusting the distance between the target object and the stand.
-All age groups can use the magnifier
-Comfortable gazing with a wide field of view
-The field of view is wide enough to cover a book.
-Usable for long hours without feeling headache and eye strain.
 
Applications
This Magnifying Glass provides distortion-free clear magnification of any object in all directions. It can be used anywhere, including offices, homes, hospitals and plants.
 
-Potential users
-Nearsighted people in their late 30s
-Those who have headache and eye strain when using reading glasses
-Suitable for those with anisopia because less image disparity is produced.
-Those who have difficulty wearing progressive lens
-Those who want to further magnify objects while wearing their reading glasses (This Magnifying Glass can be used in addition to reading glasses)
