Understanding Colored Contact Lenses

How Colored Contact Lenses Work

Tint Types

Colored contact lenses come in three main types of tints, each serving different purposes:

  • Visibility Tint: These are lightly tinted lenses, usually in light blue or green, to help you see them during insertion and removal. They do not affect eye color.
  • Enhancement Tint: These translucent lenses enhance your natural eye color, making it appear more vibrant. They are best for people with light-colored eyes.
  • Opaque Tint: These lenses completely change the color of your eyes. They are designed for people with dark eyes who want to try a different eye color.

Layering Technology

FreshLook lenses use layering technology to achieve their natural-looking colors. This typically involves three layers:

  1. Outer Ring: Defines the iris and gives the eye a larger, more pronounced appearance.
  2. Primary Color: Adds the desired color to the iris.
  3. Inner Ring: Brightens and highlights the pupil area.

Prescription Options

Optical Science Behind FreshLook Contacts

Refraction and Vision Correction in Freshlook Contacts

Refractive Errors

FreshLook contacts lenses correct refractive errors by altering the path of incoming light, ensuring it focuses correctly on the retina. This correction helps in providing clear vision for various distances.

Lens Curvature and Thickness

The curvature and thickness of the lens are precisely designed to correct specific refractive errors. For instance, toric lenses for astigmatism have different curvatures in different meridians to correct the irregular shape of the cornea.

Color Technology in Freshlook Contacts

Pigment Placement

The pigments in FreshLook lenses are placed within the lens material to prevent them from coming into contact with the eye. This ensures safety and comfort while providing a natural look.

Light Filtering

The color technology in these lenses is designed to filter light in a way that blends with the natural iris, creating a seamless color change. This technology helps in achieving a realistic appearance.

Practical Applications and Considerations

Choosing the Right Color

Matching Skin Tone and Hair Color

When choosing FreshLook lenses, consider your skin tone and hair color to find the most natural and flattering eye color. For example, warm tones like honey and brown complement warmer skin tones, while cool tones like blue and gray suit cooler skin tones.

Trying Different Colors

If you’re unsure which color to choose, consider trying a few different options. Many eye care professionals offer trial lenses to help you find the perfect match.

Proper Lens Care

Cleaning and Storage

For non-daily lenses, follow the recommended cleaning and storage guidelines. Use the appropriate contact lens solution to clean and store your lenses to maintain hygiene and comfort.
