A study by Ciba Vision, and reported by WebMD yesterday, reports 40% of contact lens users wear their contact lenses beyond the recommended change dates. It’s important to understand the hidden dangers of wearing lenses longer than prescribed.
Contact Lenses are made from different materials which determine amount of oxygen the eye receives, types of deposits that can collect on the lens, and other factors. Some contact lens material may be more conducive to build-up of proteins or lipids which can cause infection. Lack of oxygen can be detrimental long-term and the combined effects of wearing lenses longer than prescribed can lead to corneal ulcers or inflammation.
The article suggests weekly and monthly lens wearers were most likely to wear lenses longer because they forgot to change contacts. AC Lens has an email reminder service along with the LensAlert contact lens timer which can help remedy this issue. The most common reason for running over for daily contact lens wearers was to save money. Fortunately, AC Lens can help here as well with savings up to 70% below eye doctor prices.
Keep your vision health in mind and change contact lenses as prescribed by your doctor.
