Dilation of your eyes is a temporary inconvenience; however, the benefits far outweigh the inconvenience. DILATION IS THE STANDARD OF CARE TO ALLOW THOROUGH EVALUATION OF EYE TISSUE FOR A NUMBER OF EYE CONDITIONS. The use of dilation drops temporarily increases the size of your pupils, which allows us to accurately investigate the health of your eyes and many important aspects of your general health. The inconvenience of eye dilation drops will diminish gradually. It will typically take two to six hours for the effects to wear off. During this time, reading ability may be more difficult and your sensitivity to light may increase. For a short time, wearing sunglasses may be a necessary comfort. Notify staff if you feel your distance vision is excessively blurred before attempting to drive home. Thank you for your patience during this important procedure. Call your doctor immediately if you experience excessive pain, discomfort, or nausea.
