1. How do I choose colored contacts?
- Skin Tone: Warm tones suit earthy browns, golds, and hazels; cool tones complement blues, grays, and jewel shades.
- Eye Color: Dark eyes enhance with rich colors like blue, green, or hazel; light eyes look great with softer shades like aqua or honey.
- Hair Color: Warm blondes and redheads should go for green, hazel, or light brown lenses; browns and blacks are flattered by honey, green, or blue lenses.
Beyond these factors, there are other considerations such as the occasion, personal style, comfort, and prescription needs. For a comprehensive guide on choosing the perfect colored contacts, check out our blog "How to Choose the Perfect Color Lenses for You?"

5. Do you offer contacts for hyperopia?
Currently, we do not offer farsighted/plus power contact lenses. However, our R&D department is actively researching hyperopia contacts. Hyperopia, a common refractive error, causes clear vision of distant objects but blurry vision of nearby objects, resulting from the eye's shape impeding the correct bending of light onto the retina.
6. How to place an order if the left eye and the right eye have different diopters？
We offer separate prescriptions for each eye in one pair of lenses. Please select the diopter of your left and right eye on the page according to your prescription.
7. Can I wear it while sleeping?
No, it is not recommended to wear contacts while sleeping as they can hinder the eye's oxygen and hydration supply, making it more vulnerable to bacterial or microbial infections.
8. Will it come with an applicator?
We will attach a contact lens applicator for all orders with more than 1 pair of contact lenses.
9. What is the base curve and diameter of your contacts?
The base curve (BC) relates to the curvature of the contact lens. .With the right base curve, you can achieve optimal comfort, vision clarity, and good eye health. The majority of persons have an ocular base curve between 8.4 and 8.6, while the remainder fall between 8.2 and 8.9. The diameter (DIA) is the size of the contact lenses. When selecting the proper graphic diameter, the golden ratio can be used as a guide. Sclera: Eyes: Sclera = 1:2:1, at this proportion, your eyes are enlarged naturally.
To cater to the diverse needs of our customers, we offer contacts with a base curve of 8.5-9mm and a diameter of 14-14.5mm. If you're interested in a specific product, please email us at
