In the U.S., there were 24.4 million cases of cataracts in 2010, and the number is expected to double to 50 million by 2050, according to the National Eye Institute.

What is a cataract?

A cataract is a clouding of the crystalline lens inside the eye which leads to a decline in vision. Aging is the most common reason for a cataract, but other factors include disease, trauma, and certain medications. Most cataracts grow slowly over decades, but some may progress more quickly.

The crystalline lens is the structure located in the middle of the eye, in front of the retina, but behind the iris (colored part). All light that enters the eye goes through the cornea and the lens to get to the retina. If a cataract is affecting the lens, distorted vision is the result. Glasses and contacts are unable to correct the vision until the cataract is removed.

You live a busy life. With the responsibilities associated with your job, family, and well, everything, you may not get enough sleep.

More than one in three Americans don’t get enough sleep—defined as seven or more hours each—on a regular basis, according to the CDC. It’s been well established a lack of sleep can increase the risk of a number of serious health issues including high blood pressure, obesity, and depression, but does it contribute to serious or long-term problems for the health of your eyes?

Lack of sleep can leave you looking worn-down and with dark circles or heavy bags under your eyes. While this isn’t an ideal look, it’s usually nothing that a good night’s sleep can’t fix. However, as doctors learn more about our vision it has become abundantly clear that a chronic lack of sleep can have significant, and in some cases lasting, effects on your vision and the overall health of your eyes.

Besides correcting vision, contact lenses may be potential treatment devices to relieve eye pain, help the cornea to heal from injury, protect and hydrate the surface of the cornea from dry eye disease, and deliver medications to the eye.

Many ocular conditions like allergic conjunctivitis, dry eye, and glaucoma are treated using eye drops. It is estimated that 95% of the active ingredient in the medication may be lost through tear drainage. Technological advancements have made it possible to use soft contact lenses to deliver a continuous release of medication over a duration of time to treat ocular conditions and disease.

The ability of the soft contact lens to absorb and release a drug is based on the contact lens material. Their potential as a treatment depends on the water content, the thickness of the lens, the molecular weight of the drug, the drug concentration, and the time it remains within the lens.

Topical eye drops can be an inconvenient burden for patients. Delivering medication by way of a contact lens has many benefits and offers a glimpse into the future of treatment.

Let’s look at the potential benefits of using contact lenses to deliver medication to your eyes.

It’s often said the brain is an extension of the eye, and for that reason, a headache may be a symptom of a vision problem. Headaches that are related to the eye can be of the forehead, temples, behind the eyes, and at the back of the skull. They may be excruciating or dull. They may or may not be alleviated by Tylenol or sleep. They may even present with blurred vision. If you are having blurry vision and headache, your eye doctor may ask you the following questions:

Where do your headaches occur?
Do you wake up with headaches? Do they worsen with near work?
How long does your vision stay blurry when you have the headache?
If you were to grade the severity of the headache on a 1-10 scale, what number would you give?

Here are the 8 most common reasons for blurry vision and headache, and how they are diagnosed and treated.
