Rosenbloom, Jr. Pat Cummings Scholarship Julius F. Peters Memorial Award Michael G. Abstract Purpose: In winter, several patients expose inadvertently their soft contact lenses SCL to sub-zero temperatures. This study aims at measuring the effect of freezing on refractive power and water content as well as assessing visual acuity and comfort of patients who wore SCL which were previously frozen.
The method used to measure the power was to blot the lens dry on a lint-free tissue. Each measurement was repeated 3 times. Differences in WC or powers before and after freezing were each tested for significance with a mixed model ANOVA 2 brands x 3 measurements.
As long as the seal on the packet remains intact, the contact lenses will remain sterile. Patience is absolutely necessary during this process. If you leave them to defrost overnight, they should be ready to go the next morning. It is not recommended that you try to speed up the process by placing the frozen contacts in a warm setting. The heat can change the chemical properties in the solution, which can negatively affect the quality of your contacts.
As long as your contact lenses are thawed at room temperature, there should be no damage to the lenses. Once defrosted, rinse your contacts with fresh saline solution before inserting them into your eyes. While this occurrence is very rare, if your contacts have become defective or uncomfortable after being frozen, please discard the lens and contact us right away.
If you live in extremely cold regions, another thought may have crossed your mind. Wearing contact lenses in wintertime conditions can definitely leave them feeling dry, though. Your eyes and lenses are exposed to varying temperature changes — from chilling winds outdoors to high heat indoors — throughout the day that can dehydrate your eyes. It was simple, it was theoretically bad, and yet—it was dang delicious.
