Types of Glasses Lenses & Coatings Explained
Understanding the Different Types of Prescription Lenses
Choosing the right lenses is just as important as selecting the right frames. Modern spectacle lenses are available in a wide range of designs, materials and finishes, allowing them to be tailored to your prescription, lifestyle and visual requirements.
At Ilkeston Factory Specs, we provide a variety of prescription lens options and can help you understand which type of lens may be most suitable for your needs.
Single Vision Lenses
Single vision lenses contain one prescription across the entire lens.
They are commonly used for:
-
Distance vision
-
Reading glasses
-
Computer use
-
Everyday wear
Single vision lenses remain one of the most popular lens choices because they provide clear vision for a specific viewing distance and are available in a wide range of materials and thickness options.
Varifocal Lenses
Varifocal lenses provide multiple prescription strengths within a single lens, allowing wearers to see clearly at different distances without changing glasses.
Varifocal lenses are commonly chosen by people who require correction for:
-
Distance vision
-
Intermediate vision
-
Reading vision
Modern varifocal designs offer smoother transitions between viewing zones and wider fields of vision than earlier generations of multifocal lenses.
Bifocal Lenses
Bifocal lenses contain two distinct prescription areas.
The upper section is typically used for distance vision, while the lower segment assists with reading or close-up tasks.
Although many people now choose varifocal lenses, bifocals remain a practical option for some wearers.
Thin and High-Index Lenses
Higher prescriptions often benefit from thinner lens materials.
High-index lenses can help to:
-
Reduce lens thickness
-
Improve cosmetic appearance
-
Reduce lens weight
-
Increase comfort
These lenses are particularly beneficial for stronger prescriptions where standard lenses may appear thick around the edges.
Lightweight Lens Materials
Modern lens materials can significantly reduce the weight of glasses.
Benefits of our light weight lenses include:
-
Improved comfort
-
Reduced pressure on the nose and ears
-
Better suitability for larger frames
-
Enhanced everyday wearability
Many customers choose lightweight lenses to make their spectacles more comfortable during extended use.
Photochromic Lenses
Photochromic lenses automatically darken when exposed to ultraviolet light and return to a clearer state indoors.
They are often chosen by people who:
-
Spend time outdoors
-
Frequently move between indoor and outdoor environments
-
Prefer not to carry separate sunglasses
Photochromic technology has improved considerably in recent years, offering faster activation and more consistent performance.
Prescription Sunglass Lenses
Prescription sunglasses combine vision correction with sun protection.
Available in a range of colours, tints, reglaze options and lens options, they can be tailored for:
-
Driving
-
Holidays
-
Outdoor activities
-
Everyday use
Many customers choose prescription sunglasses which we can apply and alter at our in-store optical laboratory, to achieve clearer vision and improved comfort in bright conditions.
Tinted Lenses
Tinted lenses can provide both practical and cosmetic benefits.
Available in a variety of colours and densities, tinted lenses may be selected to:
-
Reduce glare
-
Improve comfort in bright environments
-
Create a specific eyewear style
-
Support certain visual requirements
Our team can advise on suitable tint options based on individual preferences and intended use. We can expertly make up prescription tinted lenses after taking all the needed lens measurements to ensure clarity and comfort
Anti-Reflection Coatings
Benefits include:
-
Improved visual clarity
-
Reduced glare
-
Better appearance in photographs and video calls
-
Increased comfort when driving at night
Many modern prescription lenses include anti-reflection technology as part of their overall lens package.
Scratch-Resistant Coatings
While no spectacle lens is completely scratch-proof, specialist hard coatings can improve durability and help protect lenses from everyday wear and tear.
These coatings are particularly useful for people who wear their glasses regularly and wish to maintain lens clarity for longer.
Blue Light Filtering Lenses
Blue light filtering lenses are designed to reduce exposure to certain wavelengths of blue light produced by digital devices and artificial lighting.
They are commonly chosen by people who spend long periods using:
-
Computers
-
Tablets
-
Smartphones
-
Digital displays
The suitability of blue light filtering technology varies depending on individual requirements and preferences.
