Refractive disorders happen when the shape of the eye doesn't let allow someone focus very precisely. They might be myopic (nearsighted), hyperopic (farsighted), or have an astigmatism, which is a focus problem caused by the cornea. Refractive disorders can be corrected by glasses or contacts.

Glaucoma is the leading cause of blindness in the United States. It happens when fluid pressure builds up within the eye and damages the optic nerve. It is treated with medications and surgery.

Diabetic retinopathy is a common complication of diabetes. The retina is tissue at the back of the eye that is filled with numerous, tiny blood vessels. When diabetes damages these delicate blood vessels, they burst or leak, leading to blind spots and blurred vision. Diabetic retinopathy can be treated with laser therapy and surgery, but often vision cannot be restored.

Macular degeneration is common in older adults. The macula is the central part of the retina and is responsible for crisp center vision. Over time, the cells in the macula begin to die, making central vision blurry. An early symptom of macular degeneration is that straight lines appear wavy.

Cataracts happen when the clear lens in the front of the eye becomes cloudy, making things look blurry or faded. They are extremely common in older people. By age 80, more than half of all Americans will have had a cataract. In early stages, prescription glasses and magnifying lenses can help. As the cataracts get worse, surgery to replace the lens may be the best option.

More than just one of the five senses, the eyes are heavily relied upon to communicate, work, and get around every day. It's important to have regular eye exams for vision stays in good shape for years to come.

• Migraines: one of the most prevalent types of headache, migraines typically last from two hours to three days, causing a throbbing pain on one side of the head. Nausea, sensitivity to bright lights, fatigue, and blurred vision all may accompany migraines. While migraines have no known cure, medications and lifestyle modifications may ease symptoms. Avoiding behaviors that may trigger migraines such as lack of sleep or loud, repetitive noises can improve headaches.
• Tension headaches: also known as stress headaches, these headaches are characterized by pain in the upper top part of the head and behind the eyes. Tension headaches are common and have no exact cause; however, certain practices may increase the likelihood of developing them. For example, wearing one's hair up in a tight hairstyle or wearing a restrictive hat can put pressure on the scalp, leading to a tension headache. Other causes of tension headaches may include alcohol or nicotine use, caffeine, teeth grinding, stress, overexertion, and eye strain. Some people find posture improvement, alternating sleeping positions, and neck exercise can alleviate tension headaches. Over-the-counter pain relievers such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve) may also reduce tension-headache pain.
• Sinus headaches: this type of headache causes pain in the sinuses, but may progress to pain and pressure in the eyes, forehead, and cheeks. These headaches are often accompanied by nasal congestion, fatigue, and ache in the upper teeth and may or may not be caused by sinus infections or sinusitis (sinus inflammation). Some sinus headaches are allergic headaches, which arise from allergic triggers such as seasonal allergies (pollen allergies) or hay fever, causing sinus pressure and facial pain. Other symptoms of allergic headaches include nasal congestion, irritated or watery eyes, runny nose, and sneezing. Allergic headaches may be treated with antihistamine medications such as cetirizine (Zyrtec). Allergic headaches are common during pollen season, which is usually around springtime.
• Cluster headaches: these headaches occur suddenly and cause stabbing, sharp pain from one eye down to the one side of the neck. They are often referred to as the most aggravating and painful type of headaches. Other symptoms of cluster headaches include nasal congestion, droopy eyelid, and enlarged pupil on one side of the face. In the past, it was widely believed that cluster headaches were caused by a bevy or "cluster" of multiple types of headaches, such as a combination of an allergic headache and a tension headache. Medical experts now recognize that cluster headaches are a separate and unique form of headache. Cluster headaches last for around twenty minutes to two hours. They may recur throughout the period of a day or several weeks, but usually dissipate within a month. Treatment for cluster headaches includes over-the-counter pain medications such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve). Prescription Prednisone can help with swelling and Verapamil may reduce pain by relaxing the blood vessels.

Living with headaches is challenging; headaches can prevent people from fully enjoying life. Medical treatment and care in avoiding certain triggers can help those with headaches begin to feel normal once again.
