A patient with glaucoma who has been using timolol (Timoptic) drops for several days tells the nurse that the eyedrops cause eye burning and visual blurriness after administration. The best response to the patient's statement is

"Those symptoms may indicate a need for a change in dosage of the eyedrops."

"The drops are uncomfortable, but it is important to use them to retain your vision."

"These are normal side effects of the drug, which should be less noticeable with time."

"Notify your health care provider so that different eyedrops can be prescribed for you."
