What Lens Colors Are Best?

Does the color of the lenses in eyeglasses have a purpose? Simply put, yes. There is more than one purpose of placing a tint on a lens.

Tint Purposes:

  • Bright Light Situations – increases comfort, good for outdoor sports
  • Computer Screen Glare – reduced
  • Fluorescent Lighting – glare reduced
  • Fashion – trends
  • Eye Strain – relaxes the eyes and reduces stress
  • Visual Enhancement – colors are more brilliant and vibrant
  • Medical – blocking light for sensitive eyes

Different Tint Color Purposes:
Yellow: a.k.a. "blue-blocker" – blocks blue light from passing through the lens –haze is decreased, images are sharper and have better contrast – popular color choice for sportsmen participating in activities where these lens characteristics are beneficial such as with target shooting.

Green (G-15): Commonly associated with Ray-Ban lenses color – often used as sunglasses lenses – most popular shades are gray and brown.

Red: color is highly uncomfortable to look through – good for specific ocular pathologies.

To meet the needs of an individual, a pair of prescription eyeglasses can have the lenses can have a custom tint applied in a short amount of time. If the tint is not “built into the lens” but rather, is on the surface of the lens then the tint can be removed at any time. A new tint color or shade may then be applied.

How is color applied to glass lenses?
Most of the time t int is applied to a glass lens during the manufacturing process by adding oxides throughout the lens material. However, a tint can be applied to a clear glass lens after it has been manufactured through a vacuum chamber process, meaning it is applied as a coating using a special vacuum process. However, the process works best during manufacturing. If the color is applied during the manufacturing process of the glass lens, the color cannot be removed.

How is color applied to plastic lenses?
Tinting can be applied to a plastic lens at the time of manufacturing but more commonly this is done after a person has selected their frames and an order is placed with the supplier. There is a large selection of colors and shades that can be applied. It is a simple process of the lens being dipped into a dye repeatedly until reaching the desired opaqueness.

A tint that has been applied to a plastic lens by the dipping process can be removed by bleaching it off. If for some reason one lens requires a tint to be removed, it is more often than not both lenses will be bleached returning both lenses to their natural clear state. This is because it is difficult if not impossible for a perfect match. All material reacts slightly different than its likeness and will produce a different result. For best results it is better to have both lenses treated the same including any stripping of color/tint and reapplication.
