We all know wearing sunscreen protects our skin from harmful ultraviolet (UV) light. Putting on a pair of sunglasses helps to protect our eyes from the same risk. 

UV radiation can raise the chance of developing eye disease, especially cancer and cataracts. While extremely bright lights in general, like direct sun, can slowly damage the retina and optic nerve.

When selecting a pair of sunglasses, go for a pair that offers complete coverage of the eye and blocks both UVA and UVB radiation. UVA rays tend to penetrate further, causing cancer, while UVB causes immediate damage to the outermost cells. Never pick up a pair of sunglasses that doesn’t say 100% UV protection. Blocking both is essential to maintaining eye health. 


But what about that other label that crops up when shopping for sunglasses?

Sunglasses are essential for those who drive or find themselves outdoors throughout the year. Keeping a pair on when in sunlight helps maintain good vision throughout your life by reducing the risk of damage. Be sure to pick one that protects against UV radiation and, if appropriate, has polarized lenses to reap the maximum rewards.

If you have an existing eyeglass prescription, picking out a pair of sunglasses isn’t as simple as selecting a pair you like with the 100% UV sticker. Taking into account your existing eyesight considerations is essential. 

As we age, our risk of many diseases and conditions naturally increase. Our eyes are no exception. 

By the time we reach the age of sixty-five, nearly one in three Americans will have developed an eye disease that can impair vision. Age-related macular degeneration, glaucoma, cataracts, and diabetic retinopathy are the top four leading causes of blindness or low vision  reduced vision.

The changes in visual acuity caused by these and other diseases are often imperceptible at first, meaning proper eye care and regular monitoring is key to early detection and treatment.

Eye dilation refers to when the pupil, the black center part of our eye, enlarges or becomes wider. Our eyes naturally dilate throughout the day, depending on lighting and other factors. This dilation and subsequent constriction of the pupil helps us focus and is primarily a safety mechanism that prevents dangerous levels of light from reaching the back of our eye. 

Eye exams can often use drops to dilate the eyes for imaging the retina. It is one of the more uncomfortable parts of visiting the eye doctor, but it can also leave you wondering; If too much light can potentially damage our eyes, why would we want or need to have our eyes dilated?

The hormonal shifts experienced during menopause cause many changes in your body. While hot flashes and mood changes tend to get the most discussion, one of the lesser-known but no less impactful symptoms can be dry eyes. Tear production decreases naturally as everyone ages, but the hormone changes associated with menopause make the problem even more acute.

Due to environmental factors or as a general course of aging, most of us will experience dry eyes at some point in our lives. Dry eyes caused by the environment might just be a nuisance. 

Dry eye disease that is experienced as a chronic condition can lead to more significant impairment, infections, and reduction in your visual acuity. Scratchy sensations can give way to difficulty focusing or eye fatigue. 

It is essential to address dry eye concerns quickly and speak to an optometrist if you haven’t been able to mitigate symptoms of dry eyes on your own.

We have all heard it at some point in our lives. We need to eat our carrots or risk losing our eyesight. Sure, a lot of that is just parents trying to get kids to eat vegetables, but there is a hint of truth to the statement. Carrots and other foods are packed with vitamins and nutrients that can help promote healthy vision.

The hormonal changes caused during pregnancy affect many aspects of your body. While most of these changes are temporary and return to normal after the pregnancy's conclusion, they can be pretty significant. It is essential to know what changes to expect, how to cope with the impacts, and when you might need to seek further medical advice.

Characterized by the body's inability to use and store sugar properly, diabetes is a chronic condition that affects the entirety of the body. Over time it can cause severe damage throughout the body, including damaging small blood vessels and capillaries. 

When this damage to blood vessels affects the retina (tissue at the back of the eye that senses light), it can cause blood and other fluids to leak out, leading to swelling of the eye called diabetic retinopathy. 

No two eyes are the same. They are a literal visual fingerprint for our unique look and how we look at the world. Affected by a host of genetic markers, hormonal changes, and environmental factors, their development and health can vary widely from individual to individual. 

A large share of those differences comes down to your biological sex. In other words, men and women do quite literally see the world differently.
