Colored contact lenses are well-established as one of today’s most popular fashion accessories. You can wear colored contacts to alter the appearance of your natural eye color, whether or not you need prescription eyewear.
Colored contact lenses are oh-so-easy to use, but there are a few things you’ll need to keep in mind if you’re going to be sure to find the best contacts for you, and you’ll need to know our top tips on how to take good care of them!
What is a colored contact?
There are two basic types of colored contact lens.
The first are prescription color contacts.
Following an eye exam by your optician, you can be prescribed colored lenses to correct near-sightedness (myopia), farsightedness (hyperopia), and irregularly shaped corneas (astigmatism). Corrected vision and the opportunity to enhance or completely change your eye color in one!
The second type of colored contact is a plano.
You’ve got 20/20 vision? These are the lenses for you! With zero power of vision correction, when used for purely cosmetic purposes they offer the same full palate of options for changing or enhancing the color of your eyes!
Beyond this, it’s good to know how they work, and how they are created in a way that mimics your eyes’ natural look!
The colored part of your eye – the iris – is comprised of many colors… and many shapes. Look closely, and you’ll notice that today’s colored contacts include countless colors dots and a swirl of colourful lines – the combination of these helps give the lenses a natural look when placed on the eye. The center of the lens – the area that cover your iris (essentially, the viewing part of your eye!) is left clear – so the tinted lens doesn’t color your view of the entire world!
Contact lenses materials
There are three colored contact lenses materials: Common regular materials, silicone hydrogel materials and non-ionic materials.
Note: Higher moisture does not mean better
Why: After wearing high-humidity lenses, they will be more moisturizing and comfortable. However, after wearing contact lenses for a long time, the contact lenses themselves will lose water due to evaporation. In order to maintain the original moisture content, it is a sponge-like polymer structure that can absorb the moisture in the eyeballs, resulting in dry eyes.
Low moisture levels can cause insufficient breathing in the pupils, which can lead to hypoxia and red blood vessels.
Conclusion: Low water content lenses are recommended for patients with dry eye
1. Daily Lenses
- High moisture content, good breathability, high comfort, easy to use, safe and hygienic, no after-sales
2.Weekly, monthly and half-yearly
- Short cycle, high cost performance
3. Yearly Lense
- High cost performance, low moisture content, not easy to dry, more color choices
But note: Pay attention to hygiene, it is recommended to wear it for 8-10 months.
1. Ensure pinch off the contact lenses when sleeping to offer corneal more breath and oxygen.
2. Due to different wear place, for example, the frame glasses is on the front of your eyes, while the contact lenses is so near to corneal that don’t have the distance effect like frame glasses, in some degree, for myopia, the degree of contact lenses is less than frame glasses.
3. Ensure pinch off your contact lenses when swimming just to avoid these microorganism in water will pollute the lens.
