About Circle Lens
How to Choose the Right Type of Circle Lens?
One should understand the following before choosing circle lenses.
I) Water Content refers to the ratio of water in the lens to the total mass of the lens. It determines the characteristics of the lens. The higher the water content, the more flexible the lens and it will lose its form more easily when handled. In contrast, the lower the water content, the more rigid the lens and the easier it is to handle.
If water content is too high, the lens will reduce moisture in the eye as it absorbs water, causing discomfort. If water content is too low, it will result in poor oxygen permeability, because oxygen passes through the water. This will result in dryness to the eyes as well.
Ideally, water content should be between 50% - 60%, but it varies among people. Experts recommend contact lenses with high water content for those whose eyes do not dry easily.
II) Diameter is the size of the lens. The bigger the diameter, the more obvious the big eye effect, when wearing the lens. Diameter serves as a good base for understanding how big the circle lens and its coverage of the iris.
However, it is the limbal ring, the black outer ring of the lens, which contributes to the enlargement effect of a circle lens. Some circle lenses have relatively small diameters but their enlargement effect is HUGE, thanks to the limbal ring. In short, don’t shop for diameter only, but look at the limbal ring design as well.
If someone has never tried circle lenses, it is good to start with a 14.0mm or 14.2mm diameter. A 14.0mm lens is sufficient enlargement for most people. No one will notice the cosmetic enhancement lenses, unless they get within a half meter and stare into the eyes.
Lenses of 14.5mm create a doll effect and others will notice this, while 14.8mm+ provides a very large-eyed anime look. These types of lenses may be recommended for special events or costume purposes, but it will be very obvious circle lenses are being worn.
III) Base Curve is one of the most important aspects when ordering lenses online. To know what lens base curve is needed, a visit to an eyes doctor (ophthalmologist) is required. Only a professional can check the eyes and tell what kind of contact lens will fit.
Wearing circle lenses with the wrong base curve is the most common reason for discomfort among lens wearers. If the diameter of the lens and the base curve are incorrect, whether it's too large or too small, this can be very uncomfortable.
When a lens fits properly, it should cover the entire cornea and move slightly with each blink. This is the right way to wear contact lenses without taking any risk. If the lens is moving a lot, dryness, irritation, itchiness and discomfort will be experienced. If this happens, take them off immediately and visit an eyes specialist.
If the lens is moving too little, the eye can become irritated and red, causing blurry vision. This happens because the lens will remain too close to the eye ball, similar to wearing clothes so tight they block blood circulation.
Most of the lenses have a base curve of 8.6mm, but not everyone has an 8.6mm BC. What is usually accepted is a +/- 0.2mm deviation. From an 8.6mm BC, there can be an 8.4~8.8mm variable and it should be okay.
If there are any questions, it is best to seek the advice of an optometrist or eye care specialist. They can determine the correct lenses necessary to fit the need.

No need if you already have a valid prescription. Otherwise, it's recommneded to obtain a valid prescription by your Optometrist or Optician before you place your order . If your prescription is still valid, but you are starting to notice some changes in your vision, you should be reexamined.
Q: Can I get a circle lens if they are a different size and base curve than I'm wearing now?
Most of our lens base curve is 8.6mm. But not everyone has a 8.6mm bc, but what is usually accepted is a +/- 0.2mm deviation. As in, for 8.6mm bc, you can be 8.4~8.8mm and you should be okay.
If you are not sure, we suggest you seek advice from your optometrist or eye care specialist.
Q: Can I wear circle lenses / colored contacts if i have astigmatism?
Sorry to tell you that our circle lenses are NOT design for astigmatism. If you have astigmatism, we suggest you purchase from other online store that carry toric lenses.
Q: Will my eye color effect the color of the lens?
To a certain extent, yes, circle lenses will blend in to your natural eye color, so there may have slight difference compare the pictures you saw on our website. (As you know, every people eye color is different). These pictures are only meant to give you an idea of how the colored contact lens will look on the eyes. They cannot be an exact representation because your underlining eye color has some effect as does the color values of your monitor.
However, halloween contacts, crazy lens and UV contacts will replaces the whole original eye colour, so it's regardless of what colour eyes you have. Only non-crazy circle lenses will blend with eye colour.
Q: How long does a contacts last?
All lens can last for 12 months as long as you take care of them properly. But if you wear them everyday, it is recommended that you dispose them off in 6~9 months.
