What Causes Astigmatism?

By

If you’ve been diagnosed with astigmatism, you’re not alone. According to the American Optometric Association, most people have some degree of astigmatism. Astigmatism is an irregular curvature of the eye’s cornea or lens that disrupts the refraction of light rays. A healthy eye should have a round shape similar to a basketball, while an eye with astigmatism has a shape more like a football. Slight astigmatism usually doesn’t affect your vision, but in more severe cases you might experience blurred or distorted vision and need corrective lenses or surgery. So what causes astigmatism?

Chances are, it’s nothing you’ve done, so be wary of anyone who tries to convince you that it’s because you sit too close to the TV or read in dim light for too long. We’ve broken down two of the common causes of astigmatism so you can better understand the condition.

Symptoms of Dry Eye Syndrome

By

Have you ever thought about how often you blink and why? Scientists have found that the average person blinks 15–20 times per minute. This means we spend about 10 percent of our waking time with our eyes closed (source). In healthy eyes, blinking replenishes the tear film, which is made of water, fatty oils, protein, electrolytes, and other substances that fight off bacteria (source). However, if you are experiencing dry eye syndrome, your eyes might feel constantly dry and gritty, no matter how many times you blink. Keep scrolling to learn more about the symptoms of dry eye syndrome, and contact your ophthalmologist to receive help.

How to Take Care of Contact Lenses

By

Despite their outward simplicity, contact lenses accomplish a complex job. These thin optical devices, which allow people to see clearly, date all the way back to 1887 – but it isn’t clear who we can thank for the invention. Some sources say that German glassblower F.A. Muller created the glass contact lens in 1887, while other reports say Swiss physician Adolf E. Fick and Paris optician Edouard Kalt teamed up to create the first glass contact lens in 1888 (source). Modern contact lenses are generally comfortable and easy to use, but they require more upkeep than glasses. Learn how to take care of contact lenses to keep your eyes healthy.
