Are cheap sunglasses hurting your eyes? A Philippine UV guide

Sunglasses from a street stall cost less than lunch, and they look the part. But near the equator, the sun is strong all year, and the wrong pair does more than fail to protect you. It sometimes leaves your eyes worse off than wearing nothing at all. Here is how to shop smarter.

Dark does not mean protected

This is the mistake almost everyone makes. The tint of a lens is just colour. UV protection is a separate, invisible filter. A very dark lens with no UV filter is the worst of both worlds: the darkness makes your pupils open wider to let in more light, and with no filter, more ultraviolet reaches the back of your eye. A pair that only looks protective is not protective.

Why UV matters here

Ultraviolet light is the same radiation that burns your skin, and your eyes are exposed to it too. Over years, UV exposure is linked to cataracts, which cloud the lens inside the eye, and to pterygium, a growth on the surface of the eye that Filipinos who work or spend long hours outdoors know well. Short, intense exposure, like glare off water or sand on a beach trip, causes a temporary sunburn of the eye surface that is genuinely painful.

What to look for

• UV400 or 100% UVA and UVB protection. This is the only claim that matters. It means the lens blocks essentially all harmful UV, whatever the tint.
• Bigger or wrap-around frames. More coverage means less light sneaking in from the sides and top.
• Polarised lenses for glare. These cut the harsh reflected glare off roads, water, and car hoods. Handy for driving and the beach, though polarisation and UV protection are separate features, so check for both.
• Lens quality. Look through them at a straight line. If it bends or warps, the optics are poor and your eyes will tire.

Colour and comfort

Grey tints keep colours natural and suit everyday use. Brown and amber lift contrast, which many drivers like. Green is an easy all-rounder. Tint colour is about comfort and preference; it is not a substitute for the UV filter.

Do not forget the kids

Children spend a lot of time outdoors and their eyes are still developing, so UV protection matters for them too. A properly UV-rated pair beats a toy-quality one every time.

The simple rule

Sunglasses are eye protection first and a style choice second. If a pair cannot confirm real UV protection, treat it as an accessory, not eye safety. Genuine sunglasses do not have to be expensive; they just have to actually filter UV.

What to ask for instead of a stall pair

You can name the lens you want. That is the difference between hoping a pair protects you and knowing it does.

Book a Vision7 eye test at your nearest Vision Express store. The seven-step exam confirms your grade and checks your eye health, so your sunwear is made to your eyes rather than guessed at.

Then ask for the Shamir Opulens Exact ordered polarized at the counter. It is made to your measurements, so you get your prescription and real glare control in one lens, which is what you want on a bright drive or a wet road after a downpour.

If you would rather carry one pair for the whole day, ask for Essilor Photochromic Elements White 1.56 instead. Clear indoors, dark on the street, so your eyes are covered the moment you step out.

Every pair comes with free lifetime ultrasonic cleaning and free lifetime custom fitting and adjustment, so sand, sweat and salt air are not the end of them.
