Stay Protected and Look Great: Understanding UV Risks
Sunglasses are undoubtedly a key fashion accessory for any summer wardrobe. But are you aware of their significant health benefits? Let's explore the often-overlooked protective advantages of wearing quality shades.
We are frequently advised to use sunscreen to prevent skin damage, ranging from sunburns to an increased risk of skin cancer. However, the harmful impact of UV rays on our eyes receives far less attention. While avoiding direct sun gazing is common knowledge, prolonged, unprotected exposure can lead to several serious eye conditions.
Key Eye Conditions Linked to UV Exposure
- Photokeratitis (Corneal Sunburn): Similar to skin, the eye's clear outer layer can get sunburned. This painful inflammation, though typically temporary, causes redness, light sensitivity, and blurred vision. It's often caused by sunlight reflecting off surfaces like water or snow, making eye protection essential for activities like skiing or sailing.
- Cataracts: More serious than photokeratitis, UV exposure is proven to accelerate cataract development. Cataracts involve the clouding of the eye's lens, commonly associated with aging and worsening vision. Surgical lens replacement is a safe and effective treatment.
- Pterygium (Surfer's Eye): This condition involves a growth of tissue on the white of the eye, often extending from the inner corner. It can cause irritation, a gritty sensation, and in severe cases, affect vision. It's not limited to athletes but affects anyone with significant sun exposure.
- Eyelid Skin Cancer: The delicate skin around the eyes is also vulnerable. While applying sunscreen near the eyes can be tricky, a well-fitting pair of sunglasses offers excellent protection for this area.

Need help taking your measurements? The following section provides a quick, easy guide.
A Simple Guide to Measuring Your Face
Taking accurate facial measurements is straightforward. Follow these preparatory steps for the best results:
- If you have long hair, pull it back to fully expose your face.
- Use a flexible sewing tape measure that can contour to your face's curves. Have a notepad ready to record your numbers.
- Position yourself in front of a mirror in a well-lit room.
Four Key Measurements
- Forehead Width: Measure the widest part of your forehead, typically midway between your eyebrows and hairline.
- Face Length: Measure from the center of your hairline down to the tip of your chin.
- Cheekbone Width: Measure the distance between the outer corners of your eyes.
- Jawline Length: Place the tape under your ear at the jaw's corner and bring it to your chin's tip. For accuracy, measure both sides and calculate the average, as faces are rarely perfectly symmetrical.
Got Your Measurements? Now, Determine Your Face Shape!
With your numbers in hand, the next step is identifying your face shape. Compare your proportions to the descriptions below to find your match.
Oval Face
Identification: The face is longer than it is wide. Cheekbones are slightly wider than both the forehead and jaw. The forehead may be taller, and cheekbones are often prominent.
Recommended Frames: Square, rectangular, geometric, cat-eye, or horn-rimmed.
Frames to Avoid: Overly round or oval shapes, and oversized frames.
Oblong Face
Identification: Similar to oval but with a longer, straighter cheek line.
Recommended Frames: Round, square, aviator, brow-line, or cat-eye.
Frames to Avoid: Narrow, rectangular, or thin frames.
Round Face
Identification: The face's width and length are similar, with soft, curved lines along the hairline and jaw.
Recommended Frames: Rectangular, geometric, D-frames, wayfarer, or cat-eye.
Frames to Avoid: Round, oval, or rimless frames.
Square Face
Identification: Strong, angular jawline with roughly equal width and length. The sides of the face form a relatively straight line.
Recommended Frames: Round, oval, brow-line, rimless, or cat-eye.
Frames to Avoid: Square or rectangular frames.
Triangle Face
Identification: The jaw is wider than the forehead, with cheekbones no wider than the chin.
Recommended Frames: D-frames, aviator, cat-eye, semi-rimless, or horn-rimmed.
Frames to Avoid: Small or bottom-heavy frames.
Diamond Face
Identification: Prominent, wide cheekbones that are broader than both the forehead and chin. Facial lines are more angular than an oval shape.
Recommended Frames: Cat-eye, oval, rimless, or brow-line.
Frames to Avoid: Rectangular or oversized frames.
Heart Face
Identification: Also called an inverted triangle. The forehead and cheekbones are similarly wide (or the forehead is slightly wider), tapering down to a narrower chin.
Recommended Frames: Oval, wayfarer, rimless, or bottom-heavy frames.
Frames to Avoid: Semi-rimless or cat-eye frames.
Essential Tips for Choosing the Right Sunglasses
Beyond fit and face shape, consider these crucial factors to ensure optimal eye protection and satisfaction.
- Prioritize 100% UV Protection: Always look for a label indicating "100% UV-A and UV-B protection" or "UV400." If unsure, an optometrist can perform a photometer test. Remember, dark lenses without proper UV blocking can be harmful, as they cause pupil dilation and allow more UV rays to enter.
- Opt for Larger Frames: When possible, choose larger frames that fit well. They cover a greater surface area, providing enhanced protection for your eyes and the surrounding skin.
- Lens Color is a Style Choice: From a protection standpoint, lens color (black, brown, blue, green) and darkness do not affect UV filtration. As long as the glasses block 100% of UV light, you can choose any tint based on your aesthetic preference.
- Polarization is Not Protection: A common misconception is that polarized lenses offer superior UV protection. Polarization only reduces glare from reflective surfaces like water or snow. It does not enhance UV blocking. Always ensure UV protection is present first; glare reduction is a secondary feature. Note: In some situations, like skiing or motorcycling, reduced glare from polarized lenses may obscure hazards like ice or wet patches.
Frequently Asked Questions
How do I measure the size of a pair of sunglasses?
Measure three dimensions in millimeters: the width of one lens at its widest point, the bridge width (distance between lenses), and the temple (arm) length. These three numbers, often separated by dashes, indicate the frame size.
How do I choose the correct sunglasses size?
Measure key points on your face (forehead, cheeks, jawline, length) and determine your face shape. Alternatively, use the measurements from a well-fitting old pair or compare lens size to a standard credit card.
What is the process for measuring my face?
Use a ruler in front of a mirror. Measure your forehead width at its widest part, your cheekbone width from outer eye corner to outer eye corner, your jawline length from jaw corner to chin tip, and your full face length from hairline to chin.
What does a 52 mm size mean for sunglasses?
A 52 mm measurement refers to the width of a single lens. This is the standard way to denote lens size, which typically ranges from 49 mm to 63 mm.
Is 59 mm considered large for sunglasses?
Yes, a 59 mm lens width is generally categorized as large. Standard sizing often considers small to be up to 55 mm, medium between 55 mm and 58 mm, and large from 58 mm to 63 mm.
