Choosing the Ideal Contact Lens


how-to-choose-the-right-contact-lens

When I first started using contact lens years back, it was tough for me to pick which one to use. There are so many types and brands! At that time, my main concern was I wanted to shift to contact lens instead of using eyeglasses. Contact lens is just less obtrusive with various daily work activities and has less chances of being misplaced somewhere during the day. Now, although I wear eyeglasses most of the time, I still use daily contact lens when I have to or when I feel like it so I still keep a stack of dailies.

It helps to consult a specialist at an eye care centre. A lot of people ask what makes an ideal contact lens, which one is suitable, comfortable and safe to use (remember the story that spread across social media years back about a girl who used bad quality contact lens?). I've always been cautious about what I put on my eyes. And it always doesn't hurt to ask professionals. From what I've learned from Alice Tan, Professional Service Manager of Vision Care, Bausch and Lomb Malaysia, the ideal contact lens is one that provides satisfactory visual performance, acceptable comfort, adequate corneal physiology, and ease of handling. On top of that, factors to be put into consideration when selecting a suitable contact lens are comfort, convenience plus the user’s needs and lifestyle.

My first set of contact lens can be used for 2 weeks but I shifted to daily contact lens after a year or so. I eventually got tired of cleaning the lens every time. A good brand to try is the Bausch and Lomb Biotrue® ONEday daily contact lens . This features the material called Hypergel and this contact lens has been considered ideal by many professionals and users alike.

If you're a contact lens user and have tried various types or brands, you might have experienced instances when the lens get dry and cause discomfort. This is a no-no for me because I work using laptops at least 8 hours a day, 5 days a week or more.

“Hypergel, a high-moisture next-generation material, was designed to work like the eye, matching the cornea’s 78 per cent water content and mimicking the tear film’s lipid layer to retain moisture. Inspired by the biology of the eye, the material combines the lens polymer with Surface Active Macromers which mimic the lipid layer of tear film to resist dehydration and maintain water within the lens for up to 16 hours. The material which combines the best features of conventional hydrogels and silicone hydrogels retains 98 per cent of moisture throughout the day, ending the day with more moisture than many lenses begin with, meets the oxygen levels an open eye needs without the use of silicone to maintain healthy, white eyes and it matches the cornea water content, which provides exceptional vision and comfort throughout the day”, said Alice Tan when asked about what was so unique about Hypergel.

When choosing a suitable contact lens, many would put the water content of the lenses into consideration. While a higher water content provides good initial comfort, it does not necessary translate into all day comfort, as this generally cause dryness at the end of the day. Biotrue® ONEday Daily contact lens is unique because it mimics the lipid layer of tear film to prevent dehydration thus provides moisture up to 16 hours, surpassing all major contact lens brand in the market today.

Alice Tan stresses the importance of good oxygen flow for the eyes. “The cornea, the outermost layer of our eyes has no blood supply of its own. Therefore, under the open eye condition, atmospheric oxygen is dissolved in tears and absorbed by the cornea. When one wears contact lenses with poor oxygen transmissibility, the oxygen supply to the cornea can be disrupted. This can lead to corneal swelling and if the condition persists, blood vessels can grow into the cornea and cause new blood vessel formation. Such complications are common when one wear contacts to sleep, particularly with lenses that are not designed for overnight wear. And in general, overnight wear of lenses is more prone to eye infection and that is why sleeping in contacts are generally not recommended”, said Alice Tan, Professional Service Manager, Vision Care Bausch and Lomb Malaysia. To maintain healthy, white eyes, Tan recommends that users choose a lens that can provide the amount of oxygen that the open eye needs. 


Above all benefits, Bausch and Lomb Biotrue® ONEday Daily’s Hypergel is the first soft contact lens material that provides UV protection. It can block 70% of UVA and 95% of UVB radiation. However, Alice Tan advised against forgoing the regular UV-absorbing eyewear such as UV-absorbing goggles and sunglasses for a complete protection.
