If life in Lake Worth Beach includes morning walks, time on the water, gardening, golf, or even just running errands under bright skies, the eyes get a lot of sun exposure. Over time, that sun adds up. Combine that with normal aging after 45, and vision can start changing faster than expected.

What UV Does to the Eyes (And What It Feels Like When It Is Too Much)

Sunlight includes ultraviolet (UV) radiation. The eyes and the thin skin around them can be affected by UV, especially without sunglasses or a hat. Over time, UV exposure is linked with several common eye problems, including cataracts and growths on the surface of the eye such as pterygium (often called “surfer’s eye”).

The short-term problem: “sunburn” of the eye

Too much UV in a short period can cause photokeratitis, which is basically a sunburn on the front surface of the eye. It can happen after a beach day, boating, fishing, or any long stretch outside without proper eye protection. Symptoms can include: pain, redness, tearing, light sensitivity, and the feeling that something is stuck in the eye. The long-term problems: damage that builds quietly

UV damage is often slow and easy to ignore until vision gets noticeably worse.

Cataracts: The lens inside the eye becomes cloudy over time, and UV exposure is a known factor that can make cataracts worse.  Pterygium: A growth on the white of the eye that can move toward the cornea and affect comfort and, in some cases, vision. UV exposure is a key risk factor.

In plain terms, UV is like weathering. One day is not the whole story, but years of bright sun without protection can show up later as glare, hazy vision, and trouble driving at night.

Why Vision Changes More After 45

After about 40 to 45, focusing up close gets harder because the lens becomes less

flexible. Reading menus, phone screens, and small print becomes more annoying. That is presbyopia, and it is normal.

The conditions that can sneak up in midlife

After 45, several eye problems become more common, and some can develop with few early symptoms:

  • Glaucoma: Often has no obvious early warning signs, but it can damage the optic nerve over time.

  • Age-related macular degeneration (AMD): Affects central vision and becomes more common with age.

  • Dry eye: Can worsen with age and can cause burning, gritty feelings, and fluctuating vision.

This is why “vision seems fine” does not always mean the eyes are healthy.

Daily Eye Protection Habits that Actually Help

  • Wear sunglasses that block UV properly

    Look for sunglasses labeled UV400 or “100% UVA/UVB protection.” Wraparound styles help because UV can enter from the sides.


  • Add a hat for extra coverage

    A wide-brim hat reduces the amount of UV reaching the eyes and eyelids, especially during peak sun.

  • Be extra careful near water, sand, and concrete Bright surfaces reflect light. That reflection can increase exposure and trigger glare.

  • Protect eyes year-round, not just in summer

    South Florida sun stays strong. Eye protection is not a seasonal habit.

Food and Nutrition that Support Healthy Eyesight


Food cannot reverse sun damage. But nutrition helps support your body’s natural defenses!


  Realistic “eye-support” grocery list

  • Leafy greens (spinach, kale, collards): commonly highlighted for eye-supporting nutrients.

  • Colorful vegetables and fruit (peppers, oranges, berries): support overall health and provide vitamins and antioxidants.

  • Oily fish (salmon, sardines, mackerel): supports general health and is commonly recommended in eye-health nutrition guidance.

  • Eggs, nuts, and seeds: useful additions for nutrient density and healthy fats.

  • Water and consistent hydration: helpful for comfort, especially if dry eye is an issue.


If the plate looks mostly beige, the eyes (and the rest of the body) are not getting enough variety, add color daily!




Dr Recommended: MacuHealth

Along with sunglasses, a hat, and healthy nutrition, Dr. Britney Caruso may recommend MacuHealth as a convenient way to support macular health.


MacuHealth is designed to support macular pigment, which sits in the center of the retina and plays a role in sharp, detailed vision. The formula uses three nutrients that are naturally found in the eye: lutein, zeaxanthin, and meso-zeaxanthin.


In a 12-month randomized clinical trial involving people with early age-related macular changes, researchers measured macular pigment and visual performance. The study reported increases in macular pigment, and some participants showed improvements in contrast sensitivity, which can affect how clearly you see in low light, glare, and night driving situations.


A practical way to think about it

  • Sun protection reduces new UV-related stress.

  • Diet supports whole-body and eye nutrition.

  • Supplements may help fill nutritional gaps for some people, especially when advised by an eye doctor.


Ask your health care professional if this is right for you before taking any dietary supplements.

Why Regular Eye Exams Matter Most

Especially in South Florida


Waiting until vision feels “bad enough” can mean missing the early stages of disease, when care is often easier and more effective! What can be missed without an eye exam:

  • Glaucoma: can develop without symptoms and still cause damage.

  • AMD: early changes can be subtle, and monitoring matters.

  • Cataracts: can build slowly and show up as glare, halos, and night driving problems.

  • Dry eye and inflammation: can make vision fluctuate and eyes feel irritated.

An eye exam is not just about updating a prescription. It is one of the easiest ways to spot problems early, track changes over time, and get clear guidance that fits lifestyle and risk factors!
