What Are Prescription Sunglasses?

Prescription sunglasses are specifically manufactured glasses that include your exact prescription but with fixed tinted lenses designed to protect your eyes from bright sunlight. Unlike transition lenses, they do not change tint; they are always shaded and often come with added features such as polarised lenses to reduce glare.

Prescription sunglasses are ideal for extended outdoor use, driving, and situations where maximum UV protection and visual comfort are a priority.

Types of Prescription Sunglasses

Standard Tinted Lenses

A single, fixed tint across the whole lens, available in a wide range of colours and darkness levels to suit your style and how much light you want blocked.

Polarised Prescription Sunglasses

Add a filter that cuts glare from flat reflective surfaces like water, wet roads, and glass, on top of your prescription. If you’re deciding whether polarised is right for you, our guide to polarised vs non-polarised lenses covers the pros, cons, and who benefits most in detail.

Gradient and Mirrored Tints

Gradient lenses fade from dark at the top to lighter at the bottom, useful for driving. Mirrored coatings reflect extra light away from your eyes, popular for very bright or high-altitude conditions.

Why UV Protection Matters

Whatever tint or style you choose, look for lenses offering 100% UVA/UVB protection (often labelled UV400). The College of Optometrists recommends UV-protective eyewear whenever you’re in strong sunlight, since cumulative UV exposure over the years is linked to cataracts and other eye conditions. Darker lenses don’t automatically mean better UV protection; always check the label rather than judging by tint alone.

How Much Do Prescription Sunglasses Cost?

Prescription sunglasses typically cost more than a standard pair of glasses, since they combine your prescription with a specialist tinted or polarised lens. Exact pricing depends on your prescription strength, lens type, and frame choice – ask your local D.I. Blow practice for current pricing when you book. Many people find the cost worthwhile if they spend significant time outdoors or driving, since prescription sunglasses remove the need to wear contact lenses or fit clip-on tints over regular glasses. If a stronger prescription is also making your everyday lenses feel thick, our guide to thin vs standard lenses is worth a read too.

Which Brands Do You Stock?

At D.I. Blow Opticians, we stock a range of designer brands that suit different styles and budgets, including Ray-Ban, Tom Ford, Maui Jim, Michael Kors, and Silhouette, among others in our brand range. Our team can talk you through which styles and lens options work best for your prescription and lifestyle.

Transition Lenses: The Alternative to Prescription Sunglasses

If you’d rather not switch between two pairs of glasses, transition lenses (also called photochromic lenses) are worth considering as an alternative. They automatically darken when exposed to UV light and become clear indoors or in low light, responding to changing conditions throughout the day.

This technology is particularly appealing for people who move frequently between indoor and outdoor environments, as it offers a one-glasses solution for both vision correction and sunlight protection.

Pros of Transition Lenses

Convenience & Versatility

Transition lenses adapt automatically to varying light conditions, indoors, outdoors, and everything in between. This means you can wear one pair of sunglasses all day without switching between regular glasses and sunglasses.

Continuous UV Protection

Photochromic lenses provide consistent UV protection whether they are clear or darkened, helping safeguard your eyes from UVA and UVB rays that can contribute to eye health issues over time.

Cost-Effective for Everyday Users

Because you only need one pair, transition lenses can be more economical than purchasing both regular glasses and separate prescription sunglasses, especially if you’re replacing old prescription lenses.

Reduced Risk of Misplacement

Fewer glasses to carry, many fewer chances of forgetting or losing your eyewear. Many wearers appreciate the simplicity of having only one pair.

Adaptive Comfort

Transition lenses can reduce glare and eye strain by automatically adjusting to changing light conditions, making them ideal for everyday activities.

Cons of Transition Lenses

Slower Response Times

Whilst modern transition lenses are faster than earlier versions, they still take time to darken and then clear, typically seconds to minutes, which might not be instant enough for some situations.

Performance in Vehicles

Because photochromic lenses depend on UV light to activate, traditional transition lenses may not darken effectively behind car windscreens that block UV rays. This means they may not be as useful as sunglasses for long-distance driving in bright sunlight.

Limited Darkness Compared to Sunglasses

Transition lenses don’t always reach the same level of tint as dedicated sunglasses, particularly in very bright conditions.

Temperature Dependency

Cold weather can slow the transition process, whilst heat can speed it up. Performance may depend on the season.

Residual Tint Indoors

Some people notice a slight tint under the bright indoor lighting, which might affect visual clarity or personal preference.

Which Is Right for You?

There’s no single answer; it depends on your lifestyle, daily habits and visual priorities:

• Prescription sunglasses are ideal if you spend significant time outdoors, especially driving, playing sports, or in particularly bright environments, and want maximum tint strength and, if you choose, polarisation.
• Transition lenses suit those who want simplicity and continuous UV protection without carrying a second pair of glasses.

At D.I. Blow Opticians, we can assess your visual needs during a comprehensive eye exam and help you decide whether transition lenses, prescription sunglasses or both are the best solution for you.

FAQs

Are Prescription Sunglasses Worth It?

For most people who spend meaningful time outdoors or driving, yes, they give full UV protection and clear vision at your exact prescription without needing contact lenses or clip-on tints. If you only need sun protection occasionally, transition lenses or a low-cost non-prescription pair over contacts might suit you better.

Can You Get Polarised Prescription Sunglasses?

Yes, polarisation can be added to prescription lenses to reduce glare from water, roads, and glass on top of your prescription and tint.

How Much Do Prescription Sunglasses Cost?

Cost depends on your prescription, lens type (standard tint, polarised, or gradient), and frame choice. Ask your local D.I. Blow practice for current pricing.

What’s the Difference Between Prescription Sunglasses and Transition Lenses?

Prescription sunglasses are permanently tinted and offer maximum sun protection outdoors. Transition lenses adapt automatically between clear and dark depending on light conditions, so you only need one pair of glasses. Both can be fitted with your exact prescription.

Can I Get Prescription Sunglasses in any Style?

Yes, most frame styles can be made with prescription sunglass lenses, including designer brands. Our team can advise on frame shapes and lens types that suit your prescription and face shape.

Getting Maximum UV Protection

More time outdoors means more UV exposure, so look for these features when choosing sunglasses:

• UVA and UVB protection
• A UV400 label, which confirms 100% protection against both UVA and UVB rays
• A CE Mark, showing the sunglasses confirm to British Standards Institution (BSI) and EU safety standards

Darker lenses don’t necessarily block more UV rays. Always check the label rather than judging by tint alone, and remember that UV rays penetrate thin cloud, so sunglasses are worth wearing beyond just bright, sunny days. For the technical detail on how UV coatings work at a lens level, our lens coating guide covers this in full. For a deeper dive into UV400 specifically, see our guide on whether you need UV400 protection, or our seasonal tips on protecting your eyes from UV rays this summer.

Visible Light Transmission (VLT)

Depending on your needs, look out for the VLT (Visible Light Transmission) percentage on your next pair of sunglasses. The higher the percentage, the more light that passes through the lens to your eyes.

• 0-19% VLT: Best for bright, sunny conditions
• 20-40% VLT: For all purpose use
• 40+% VLT: Good for overcast and low-light conditions
• 80-90% VLT: Used for very dim and night conditions

Oversized or wraparound lenses will protect a larger area of your face, regardless of VLT.

The Different Types of Sunglasses Lenses

When choosing which sunglasses lenses are right for you, ask yourself the following:

• How often will you be wearing your sunglasses?
• Do you want to block blinding, reflective glare?
• Where will you be wearing your sunglasses?
• What activities will you be doing whilst wearing sunglasses?
• Do you want a bespoke tint, gradient, or lens feature?
• What’s your budget?

Gradient Lenses

Traditional frame tints consist of a single block colour, but gradient sunglasses lenses have two tones, with a darker tint at the top of the lens that fades to a lighter tint at the bottom. This makes them ideal for driving and general use, shielded from sunlight above, with a clear view of objects closer to you.

Mirrored Lenses

Mirrored lenses have a thin, reflective film applied to the lenses that reflects light and glare away from your eyes. Because of this, mirrored sunglasses are popular for those participating in outdoor activities such as skiing, water skiing, and running, as they minimise light disturbance and offer a better viewing experience.

Polarised Lenses

The specialised coating on polarised sunglasses lenses blocks glare from reflective surfaces such as water and wet roads. These are great for any lifestyle and can be fitted to any shape, size, tint, gradient, prescription, or brand of sunglasses. Our polarised vs non-polarised guide covers the pros, cons, and who benefits most in full detail. For more on how polarised lenses work day-to-day, our guide to everything you need to know about polarised sunglasses covers this in full.

Photochromic Lenses

Photochromic lenses, also known as transition lenses, adapt automatically to the amount of light available, darkening outdoors and clearing indoors. They’re a popular alternative to a dedicated pair of prescription glasses. Our prescription sunglasses guide compares photochromic lenses against fixed-tint prescription sunglasses in detail, including cost and which suit different lifestyles.

Lens Colours

While certain tints are recommended for particular activities, lens colour is mostly a personal preference and doesn’t affect how well the sunglasses protect your eyes from UV rays.

• Grey: The most neutral tint. It affects your colour vision the least. Great for most activities.
• Green: Provides contrast and helps reduce glare and eye strain. Ideal for golf, tennis and everyday use.
• Red or Rose: Block blue light so they improve driving visibility while reducing eye strain. They enhance detail and increase depth of field.
• Blue or Purple: Deliver enhanced colour perception. They complement most skin tones and work well in foggy weather.
• Amber or Brown: Increase contrast and heighten visual acuity. Perfect for most sports since they improve contrast against green grass and blue skies.
• Yellow, Orange, or Gold: Improve the visibility or objects, especially in moderate to low light conditions. Excellent for both indoor and outdoor activities.

Keep Them Clean, Keep Them Safe

Store your sunglasses in a protective hardshell case when not in use to significantly reduce the risk of damage. For a full cleaning routine and more tips on making your sunglasses last, see our guide to caring for your sunglasses.

Before buying new sunglasses, we recommend you book an eye test with your local D.I. Blow Opticians. You might be considering non-prescription sunglasses, but even if you can pass a driving vision screening without glasses, you might see significantly better with prescription sunglasses. Only a comprehensive eye exam will tell you for sure.

FAQs

What Does UV400 Mean on Sunglasses?

UV400 means the lenses block 100% of the UVA and UVB rays with wavelengths up to 400 nanometres – effectively all the UV radiation that reaches the Earth’s surface. Always check for this label regardless of how dark the lenses look, since tint and UV protection aren’t the same thing.

What’s the Best Lens Tint for Sunglasses?

It depends on your main use. Grey is the most neutral all-rounder; amber/brown is popular for sports thanks to better contrast; and yellow or orange lenses improve visibility in low light. None of these tint colours affects UV protection, which comes from the coating, not the colour.

What Is VLT and Why Does it Matter?

VLT (Visible Light Transmission) measures how much light passes through your lenses. A lower percentage suits bright, sunny conditions; a higher percentage suits overcast days or low light. Choosing the right VLT for how you’ll actually use the sunglasses matters as much as tint colour.

Do Darker Sunglasses Lenses Give Better UV

No, tint darkness and UV protection are separate things. A pale lens with a UV400 rating protects your eyes fully; a very dark lens without one may not. Always check the label.
