by - October 11, 2017

I know it has been awhile since I write review on lens,
so here is a quick one for today :)

 Tbh, it took me very long to finish my contact lens stock mainly because I am such a hoarder and I enjoy switching between different ones depending on my mood. Tell me if you felt the same too!

Before I begin, I have to enphasize that everyone's eyes condition is different and therefore, what suits me may not work the same for others. I used to think that the higher level of water content in a lens is better (typical Asian mentality) until I learnt more about it.

Here are 3 types of contact lens category
Low water content (up to 45%) – modern silicon-hydrogel contact lenses, used in contacts that are intended for continual wear. They have almost 100% oxygen permeability.

  • Mid water content (up to 60%) – hydrogel contact lenses, suitable for most users.

  • High water content (up to 90%) – hydrogel contact lenses for more sensitive eyes. Suitable for prevention of the dry eye syndrome

  • Basically any lenses with water content above 65% is considered high moisture but that does not mean it increases oxygen transmission. The more water contact lenses contains, the more difficult it is for oxygen to get to the cornea where the surface is dependent on atmospheric oxygen. Irreversible vascularization happens when there is not enough oxygen to reach your cornea, which explains fine red veins forming on the sclera. Those who suffer from dry eyes syndrome should avoid high water content lenses as it can have adverse reaction as moisture in the lens can draw the eye's natural tears away.

    Before we make any judgement, here is one more fact. The less water contact lenses contain, the less comfortable they are. So, moisture level does place an important role in keeping your eye free from painful red and dry state.

    Lenses that are made of Silicone hydrogel material achieves very high oxygen transmission regardless of its water content. However, this type of lenses are generally more expensive compared to other lens in the market.
    In my personal opinion, I find the blister packs of Biotrue is convenient to bring around, regardless of short trip or to any event. It claimed to hold 98% moisture up to 16 hours (subject to environment condition) but for me, it can only last me up to 6-8 hours before I felt any eye dryness. At times where I have to be out the entire day, I have to remember to bring along contact lens cleansing solution or eyedrops for fast relieve. At the end of a long day, taking it off is a wth horror drama as the lens stuck close to my eyeballs. Moisturing it before removal helps ALOT!

    As much as I hope to like it, it is most unfortunate the Biotrue ONEday lenses did not meet my expectation and my rating is 4/10. This is purely my personal experience and it may work differently for others.

    That's all for now.
