How Do Color Contact Lenses Work?

Feb 03,2023 | Coleyes

Color contact lenses are a popular way to change the color of your eye. They work by filtering light that enters the eye, which allows only certain wavelengths to pass through while blocking others. The result is a hue shift in your natural iris that makes it appear as though you have different colored eyes.

Color contact lenses work by filtering light that enters the eye. The same way sunglasses filter light to tint your eyes and make them appear brown or green, color contacts work by filtering light to change the color of your eye. They can permanently alter the appearance of your iris (the colored part of your eye), or they can temporarily change the appearance for a few hours at a time.
  • Filters: When looking at an object in front of us, we see reflected images from all around us in our retinas. We have three kinds of cones in our eyes—red, green and blue—that are responsible for detecting these colors and transmitting information about them to our brains so that we can see with depth perception as well as detail. Color contact lenses filter out various wavelengths of visible light according to whatever color they’re designed for, allowing only those wavelengths through which would actually produce redness within the iris itself.*

There are two different types of color contact lens materials: hard and soft.

Hard contacts are made of rigid plastic or gas permeable materials.

Hard contact lenses are made of rigid plastic and do not allow oxygen to pass through the lens, which means that they can be worn for longer periods of time. These also tend to be more comfortable than soft contact lenses as they do not require any gels or solutions. They are a good choice for people who have dry eyes or allergies.
Hard contacts tend to have better vision correction capabilities than soft ones. You can get them in both prescription and non-prescription designs; however, you will need an eye exam before purchasing either type so that your optometrist can determine whether or not they’re right for you (and if the prescription is correct).

Soft contacts are soft, flexible lenses that can be worn for longer periods of time than hard lenses.

Soft contacts are soft, flexible lenses that can be worn for longer periods of time than hard lenses. Soft lenses offer a wide range of comfort and vision correction options. They are more comfortable to wear than hard lenses because they're thinner and more breathable, which allows them to move slightly when you blink or talk. They're also more flexible than hard lenses, so they adapt easily to your eye's shape while still being durable enough to keep their shape over time. Finally, soft contact lenses are easier to put in and take out than hard contacts because they don't need to be cut from sheets before use; instead, they come pre-cut from manufacturer-approved materials like silicone hydrogel (SH) material

Color contact lenses are worn on the eye like any other regular lens.

Color contact lenses are worn on the eye like any other regular lens. The only difference is that color contact lenses have a colored tint, while regular ones don't. They can be worn for a long time, but they need to be removed and cleaned regularly.
The most common types of contact lenses are: -Tinted or Colored Contact Lenses: These are used to change the color of your eye, like turning brown eyes blue. They’re made from high-quality plastic and are very comfortable to wear. -Daily Wear Lenses: These lenses can be worn for up to one year without needing to be replaced. They're also easy to care for because you only need to put them in once a day and remove them before sleeping.

Color contact lenses have similar health risks as regular contact lenses, such as eye irritation, dry eye and corneal abrasions.

Dryness is the most common side effect of wearing color contacts. Your eyes may feel dry and uncomfortable for up to two weeks after you start wearing them.
It’s also important to monitor your eyes for any signs of irritation or infection after starting to wear color contacts. If you notice redness, blurred vision or pain in your eyes, see an optometrist immediately!

With proper care and cleaning, color contact lenses can be a safe way to change your eye color

Color contact lenses can be a fun way to change your eye color, but with proper care and cleaning, they can also be a safe way to do so.
  • Wash your hands with soap and water before handling the lenses.
  • Use a sterile solution or hydrogen peroxide (never tap water)to clean them with fresh solution each time you put them in. Never use saliva or other liquids because they may contain bacteria that could harm your eyes.
  • When you remove your lenses, remove them carefully. Do not squeeze or rub them against anything else as this could damage their shape and cause problems when putting them back in. Rinse them with sterile water or solution to remove any debris and store them in a clean, dry container that is unlikely to leak.
 
We hope that this article has given you a good understanding of the benefits and risks of color contact lenses. If you're interested in changing your eye color, be sure to talk with your optometrist about whether it's right for you or not!
