Prescription Sunglasses Singapore — Complete Buying Guide

Why prescription sunglasses are different from regular sunglasses

A prescription sunglass lens has to do two jobs at once that pull in different directions: correct your vision precisely, and reduce visible light by 80-90% or more depending on the lens category. Getting both right means the tint has to be applied evenly across a lens that already has a corrective curve, which is a more technical grinding and coating process than tinting a flat, non-prescription lens.

This is also why prescription sunglasses cost more than both regular prescription glasses and regular sunglasses on their own — you're paying for the correction, the tint or polarising film, and usually a UV400 coating, all applied to a single precision-ground lens.

Your options: direct-glazed, clip-on, and fitover

Direct-glazed prescription sunglasses: The tint or polarising film is built into the lens itself, ground to your exact prescription. This gives the best optical clarity, the most natural field of view, and looks identical to a normal pair of sunglasses. This is the standard choice for anyone wearing prescription sunglasses regularly.

Clip-on sunglasses: A tinted lens attachment that clips onto your existing prescription glasses. Cheaper and reusable across different frames, but adds bulk, can slip, and often introduces slight distortion at the edges where the clip lens doesn't perfectly match your lens curve.

Fitover sunglasses: Oversized sunglasses designed to fit over your existing prescription glasses entirely. Useful as a low-cost temporary solution or for occasional outdoor use, but bulky for daily wear and not a long-term answer if you spend significant time outdoors.

For anyone in Singapore who is outdoors regularly — commuting, exercising, or simply walking between buildings in tropical sun — direct-glazed lenses are worth the extra cost over clip-ons.

Lens choices that matter in Singapore

UV400 — non-negotiable

Singapore sits close to the equator with a UV index that regularly hits 11+ (extreme) around midday. UV400 blocks effectively all UVA and UVB radiation and should be treated as a baseline requirement, not a premium add-on, on any prescription sunglass lens. See our full UV400 guide for what the rating actually means.

Polarisation

Polarised lenses cut horizontal glare — the kind that bounces off wet roads, car bonnets, and water. For driving, cycling, or time near East Coast Park and the reservoirs, polarisation is a genuinely useful upgrade, usually adding SGD 30-100 to the lens cost. See our guide on polarised vs non-polarised sunglasses to decide if it suits your prescription and use case.

Lens index and thickness

Stronger prescriptions (roughly beyond ±4.00) benefit from a high-index lens (1.67 or 1.74), which stays thinner and lighter than a standard 1.50 index lens at the same power. This matters more for sunglasses than regular glasses because sunglass frames tend to be larger, which magnifies edge thickness on strong prescriptions.

Photochromic (transition) options

Some wearers prefer a single pair of glasses that darkens outdoors and clears indoors. Photochromic lenses do this, though Singapore's heat means they don't reach quite the same maximum darkness as they would in a cooler climate. See our photochromic lens guide for the trade-offs.

What prescription sunglasses cost in Singapore

• Budget (SGD 80-150): Basic frame with single-vision tinted lenses, standard UV protection, no polarisation.
• Mid-range (SGD 200-400): Better frame materials, polarised lens option, UV400 as standard, sometimes anti-scratch or hydrophobic coating.
• Premium (SGD 500-800+): Branded frames, high-index lenses for strong prescriptions, premium polarised or photochromic lens technology, progressive prescription options for presbyopia.

Progressive (multifocal) prescription sunglasses sit at the higher end of each bracket since they require more complex lens grinding and a proper fitting to get the corridor placement right.

Where to get them made

Singapore has a dense network of optical retailers across malls and neighbourhood centres, most of which can glaze prescription sunglasses in-house or send lenses out for grinding. A general optical chain is usually the fastest route to a same-week pair, and lets you try frames on before committing. Worth noting: not every eyewear brand you'll come across does prescription work — several popular Singapore sunglasses labels sell non-prescription frames only, so confirm this upfront before falling for a frame you can't actually glaze to your prescription.

Buying prescription-ready frames online

Not every sunglasses brand supports prescription glazing — many performance and lifestyle brands sell non-prescription only, or require sending your prescription to a separate lab. Singapore brand Aura Shades offers a dedicated prescription sunglasses service, letting you pair their lightweight sport and lifestyle frames with a corrected lens rather than choosing between vision correction and frame style.

Whichever route you take, confirm three things before ordering: whether the lens is direct-glazed or a clip-on, whether UV400 and polarisation are included or add-ons, and what the return or remake policy is if the fit isn't right once the glasses arrive.
