About Balafilcon A Contact Lenses Contacts
Features of Balafilcon A Contact Lenses
In the 1970s, doctors typically prescribed contact lenses made of hydrogel — a thin, pliable material that easily conforms to the surface of the eye — due to their comfort and ease of use. However, a major downside of hydrogel contact lenses is their tendency to dry out. The water in hydrogel contact lenses gradually evaporates, making them uncomfortable to wear for long periods. Hydrogel also has low permeability to oxygen, which the eye needs to stay white, moist, and healthy.
Eventually, contact lens manufacturers were able to improve the hydrogel polymers used in contact lenses. This improvement resulted in the introduction of silicone hydrogel contact lenses. From the name itself, silicone hydrogel is a polymer that contains both hydrogel and silicone — a gel-like polymer known for its high degree of flexibility. Like hydrogel, silicone hydrogel contains water. But unlike hydrogel, silicone hydrogel is porous and has better oxygen permeability.
In fact, silicone hydrogel allows five times more oxygen to reach the eye than hydrogel. With silicone hydrogel, contact lens wearers are less likely to suffer from a lack of oxygen supply to the eye, which can lead to acute inflammation, swelling, or infection. For this reason, silicone hydrogel lens materials like balafilcon A are much more suitable for overnight or continuous wear than hydrogel lens materials. Currently, balafilcon A is FDA-approved for up to six nights and seven days of continuous wear.
Note that one major disadvantage of balafilcon A contacts and other silicone hydrogel contacts is their tendency to collect deposits more quickly than hydrogel contacts. Balafilcon A contacts and other silicone hydrogel contacts may also not be suitable for people who are allergic or sensitive to silicone.
Popular Balafilcon A Contact Lenses
Popular brands of balafilcon A lenses include those belonging to the PureVision® brand of contacts by Bausch + Lomb, namely, PureVision, PureVision Toric, PureVision Multi-Focal, PureVision2, PureVision2 For Astigmatism, and PureVision2 Multi-Focal.
PureVision and PureVision 2 contacts are particularly suited for people who spend long hours staring at a digital screen, while PureVision Toric and PureVision2 For Astigmatism are ideal for people who have vision problems due to astigmatism — an imperfection in the curvature of the eye that causes blurred vision. PureVision Multi-Focal and PureVision 2 Multi-Focal, on the other hand, are designed for people who have vision problems due to presbyopia — an age-related eye condition that makes nearby objects appear blurry.
All six PureVision contacts are monthly lenses that can be worn daily for up to 30 days or continuously for up to six nights and seven days. They’re ideal for anyone who needs a flexible wearing schedule, such as busy professionals and people with highly active lifestyles.
Additionally, all six PureVision contact lenses are available in near- and farsighted prescriptions.

How to Insert and Remove Balafilcon A Contact Lenses
Balafilcon A contacts are soft contacts and as such, you should follow the standard procedure for that type of lens. Start by washing your hands with mild soap and water, then dry them with a lint-free towel. Scoop your first lens out of the case with your index finger of your dominant hand. Rinse it with a cleaning solution that’s specially formulated for soft contacts. Inspect the lens for any tears or debris, and make sure it’s not inside-out. Using the middle finger of your dominant hand, pull down your lower eyelid. If necessary, use the middle finger of your non-dominant hand to pull your upper eyelid. Look upward and gently put the lens on your eye. Blink a few times to center the lens. Repeat this with the other lens.
To remove balafilcon A contacts, hold your eyelids open and gently pinch the lens between your index finger and thumb. Carefully lift the lens off of your eye. Repeat with the other lens.
