Scleral lenses are a unique type of specialty contact lens used for patients with irregular corneas, dry eyes, corneal scarring or other eye conditions that make regular contact lenses difficult to wear. These large-diameter (19-24mm) rigid gas permeable (RGP) contact lenses vault over the cornea and rest on the white part of the eye called the sclera to provide continuous hydration, dry eye relief and comfort.
They also serve as a great choice for those with presbyopia or post-surgical ametropia who are unable to wear other forms of vision correction. The larger diameter of scleral lenses allows them to cover the full length of the cornea and to vault over the iris, making them easier to handle, more stable and less likely to cause discomfort.
The FDA classifies these colored contacts as medical devices, meaning they are regulated under the same laws and standards as other medical devices. This means that these lenses must be evaluated by an ophthalmologist or optometrist to determine whether they are safe for you to wear.
These colored contacts come in a wide variety of materials and designs, allowing you to choose the perfect pair for your unique personality. The most common materials used for cosmetic colored lenses are hydrogel and silicone hydrogel, which have a higher oxygen permeability than standard lenses.
Some of these colorful contact lenses are also available in natural effect. These natural circle lenses are designed to mimic the shape and size of your own iris and they are made of soft material, ensuring that they are comfortable and durable.
You can find these circle lenses in many colors and effects including hazel, green, yellow, red, pink, blue, purple and more. They are perfect for adding a dramatic touch to your look and can even make you feel more confident in social situations.
Colored contacts come in a wide range of sizes, so there is sure to be a pair that will fit your needs. At CandyLens, we have a wide selection of circle lens types, brands, prescription and diameter to suit your preferences.
Big eyes circles and colored contact lenses are not only a trend in Asia, but they have become a safe and popular way to express yourself as a fashion statement or just for fun. The biggest problem with this trend is that people are wearing these lenses too big and they are causing the eyes to become over-exposed to light.
This can be uncomfortable for some people and lead to eye irritation and other health problems. To avoid this, always clean your lenses and their cases daily, especially if you are wearing them regularly or if they are very large in diameter.
Most of the circle lenses are produced in Korea and Japan, but they have been growing in popularity all over the world, with celebrities and models from around the globe showing them off in their everyday lives.
It is important to know that these are not legal in most countries, so you should be careful if you are thinking about trying them out for yourself.
