Key Information on your Contact Lens

Contact lenses are placed directly on the surface of your eye to correct your vision. They can correct short-sightedness (myopia) and long-sightedness (hyperopia). They can also correct astigmatism and age-related long-sightedness (presbyopia). Contact lenses are a great choice for anyone wants to switch between lenses and glasses frequently.

Most soft lenses are made out of a material known as Hydrogel, a water absorbing polymer that are breathable and uses the water content to transmit oxygen to the eye through the lens keeping your eyes healthy and feeling fresh.

There are different types of contact lenses available to suit your individual vision and lifestyle needs. 1day disposable contact lenses or daily disposable contact lenses are designed to be worn for one day and then thrown away. 1day disposable contact lenses are great for people who are looking for contact lenses that are easy to maintain without having to worry about cleaning them. Wearing a fresh pair of lenses every day is the most hygienic way of wearing contact lenses as there is less time for dirt and allergens to build up on the surface and cause irritation. Reusable contact lenses are contact lenses you wear every day for up to a fortnight, a month or a year. Just clean them and leave them in disinfecting solution before you go to bed. Then put them back in first thing in the morning.

Contact lenses are comfortable and with new lens material available it will not make your eyes feel dry after wearing contact lenses. Try Seed 1dayPure Series of contact lenses, it is created to allow contact lens wearer to realize the comfort of wearing a contact lens again.

People with astigmatism can now wear contact lenses, thanks to our unique toric lens design which helps to provide a stable and comfortable lens fit.

Advancing age is no longer the barrier to successful contact lens wear. With Seed 1dayPure Multistage contact lens, a contact lens developed for presbyopia patients you do not have to go through the hassles of switching between reading glasses and regular glasses for distant vision.

High minus power should not stop you from wearing contact lenses, Seed 1dayPure Moisture now comes in powers up to -16.00 diopters, you can continue to have the freedom of movement to live an active lifestyle.

If you follow your eye care practitioner's instructions regarding how to care for your lenses and follow proper care routines wearing contact lenses are very safe.

Contact lens is the barrier which reduces the amount of oxygen reaching the cornea. The value of oxygen permeability is the indicator for measuring this barrier: higher value indicates that more oxygen can reach the cornea. "Oxygen Permeability" is the value for the diffusivity (D) of the oxygen goes through the lens times the solubility (k). Therefore, the oxygen permeability is determined by the "material" of the lens, and has nothing to do with its shape or curve design.

Compared to oxygen permeability, oxygen transmissibility takes the value "t" (the lens' thickness) into consideration; that is, oxygen transmissibility is equally related to the thickness, material, and geometric design of the lens. The value of its thickness is the harmonic mean of the measurements of its thinnest central optic zone. But since the lens with different power has different thickness, we use -3.00 D as the standard reference. (The central optic zone's thickness of soft contact lenses falls between 0.07~0.10mm) Ideally, if the lens is designed to be very thin, its oxygen transmissibility can be greatly elevated even the material has low oxygen permeability. However, if considering the factors such as optical property, physical property, yield rate and usability, more problems would occur if the lens is too thin. Regardless of high water content, SEED 1dayPure Moisture and Multistage excels in morphological stability. Thus, the thickness of the lens centre is 0.07mm (-3.00D), which is the thinnest class among daily disposable high water content contact lenses. Due to high water content and the thin lens design, the oxygen transmissibility becomes 42.9. This value is high enough to transmit adequate oxygen, which is sufficient for human eyes.
