From classic rectangular frames to trendy cat-eye shapes, lens types like progressive or bifocals, and blue light blocking, we’ll cover it all. With a few insider tips and tricks, you’ll be an expert on the different types of glasses in no time.

Types of Glasses

Eyeglasses, “spectacles”, or simply “glasses”, are lenses mounted in a frame that are worn in front of the eyes. Eyeglasses are wearable accessories and medical devices that help you see. They consist of a frame that holds 2 pieces of glass or plastic to correct refractive errors.

They can help correct vision issues like nearsightedness, farsightedness, and astigmatism. Glasses work by refracting light in a way that compensates for irregularities in the eye’s focusing ability. This allows the light to properly focus on the retina for clear vision.

The lenses in glasses come in different materials, like plastic or glass. They can also have varying designs like bifocals (for close and distant vision) or progressives (a gradual transition between prescriptions).

Sunglasses

Sunglasses are tinted eyewear designed to protect your eyes from the sun’s harsh rays. They reduce glare and block a percentage of ultraviolet (UV) light.

Protecting your eyes from UV damage can prevent conditions like cataracts, macular degeneration, and pterygium. Sunglasses also help you see better in bright conditions.

Popular Sunglass Types

• Aviators – Iconic teardrop shape originally designed for pilots.
• Wraparounds – Curved for enhanced coverage and side protection.
• Oversized – Large lenses that provide maximum sun blockage.
• Mirrored – Reflective coating reduces glare from water or snow.
• Polarized – Special filter eliminates glare from flat surfaces.

Sunglass lenses absorb certain light wavelengths while letting others through. Different tints filter different amounts and colors of visible light. The darker the lens, the more light it blocks.

Prescription Glasses

Prescription glasses are eyeglasses customized to correct vision problems like nearsightedness, farsightedness, astigmatism, and more. They are designed with prescription lenses that refract light to focus images clearly on your retina.

Prescription lenses bend light rays to compensate for refractive errors in your eyes. This allows the light to properly focus on your retina, improving blurry vision.

Common Types of prescription glasses include:

• Single Vision Lenses: These provide clear vision at one distance, near for reading or far for driving. They’re the most basic type of prescription lenses.
• Bifocal Lenses: These lenses have two prescriptions, the top for distance vision and the bottom for near vision, separated by a visible line. Great for those who need vision correction for both distances.
• Progressive Lenses: Unlike bifocals, these seamlessly transition between all distances, near, intermediate and far, with no visible lines. Convenient but can take some adjustment.
• Occupational Lenses: Optimized for specific working distances like computer use or other tasks. Provide the sharpest vision within that range.
• High-Index Lenses: Thinner and lighter than regular plastic lenses while providing the same prescription power. Ideal for stronger prescriptions.
• Photochromic Lenses: These transition from clear indoors to tinted outdoors, acting like sunglasses. Convenient for light sensitivity or frequent transitions between bright and dim lighting.

Beyond correcting vision, prescription glasses protect eyes from UV rays, blue light, and eye strain. They enhance vision for activities like driving, reading, computer use, and sports.

Non-prescription Glasses

Non-prescription glasses, also known as ‘Plano’ or ‘Clear’ glasses, are eyeglasses without any corrective lenses. They don’t have any added magnification or vision correction. They are ready to wear and can either be worn as a fashion accessory or can be taken to a local optician to be changed for prescription lenses.

These glasses are designed for fashion, protection, or blue light filtering purposes rather than vision correction. The lenses are simply tinted, polarized, or treated to block certain light wavelengths.

Popular Types of Non-Prescription Glasses

• Blue Light Blocking Glasses
• Computer Glasses
• Sunglasses
• Safety Glasses
• Fashion Frames

Non-rx glasses offer style, UV protection for outdoor activities, reduced eye strain from digital screens, and enhanced contrast/clarity. They’re perfect for looking good while shielding your eyes.

Ultimately, non-prescription eyewear serves to protect your eyes, reduce glare/reflections, filter harsh lighting, and allow you to make a bold fashion statement, all without any vision correction.

Digital Protection Glasses

Digital protection glasses, also called computer glasses or blue light-blocking glasses, are specialized eyewear designed to filter out harmful blue light emitted from digital screens. They offer relief from digital eye strain, headaches, and disrupted sleep patterns caused by prolonged screen time.

These glasses have lenses treated with a special coating that selectively blocks or filters out the blue-violet portion of the visible light spectrum emitted by digital devices. This reduces glare and brightness while improving contrast and visual comfort.

Types of Digital Glasses

• Blue light filter lenses
• Anti-reflective (AR) lenses
• Photochromic lenses
• Progressive lenses
• Computer bifocals

Digital protection glasses are widely used by professionals who spend long hours staring at computer screens, tablets or smartphones. They help reduce eye fatigue, dry eyes, blurred vision and headaches associated with digital eye strain.

What are Eyeglasses Lenses?

Lenses for glasses are pieces of material that are placed inside a frame to provide the wearer with good vision while also protecting the eyes. Lenses are typically glass or plastic and can be prescription or non-prescription. Eyeglass lenses are used for vision correction, most typically for refractive defects such as myopia (nearsightedness), hyperopia (farsightedness), presbyopia, and astigmatism. Glass lenses come in various materials. The most common are plastic lenses made from lightweight polymers like CR-39 or polycarbonate. These are cost-effective and durable options.

For higher-end lenses, there are hi-index plastics that are thinner and lighter. And for the best visual clarity, many choose glass lenses despite being heavier.

The lens type (single vision, bifocal, progressive) determines how it refracts light to correct your vision. Anti-reflective, scratch-resistant, and UV coatings can further enhance the lenses. Photochromic lenses automatically darken in sunlight, while polarized lenses reduce glare. There are specialty tints and mirror coatings too.

The most important factor is getting the right prescription power in your lenses to correct nearsightedness, farsightedness or astigmatism. Precise measurements ensure crisp vision.

Different Types Of Eyeglasses Lenses

These are the types of lenses for glasses:

Prism lenses

Prism lenses are a type of glass lens that refracts light to ensure it enters the eye properly. These lenses are prescribed to treat vision conditions, including double vision.

Tinted lenses

Tinted lenses are commonly used in sunglasses to shield the eyes from ultraviolet rays. There are also tinted lenses in a variety of colours that are used as fashion sunglasses but do not provide eye protection.

High index lenses

High-index lenses are lighter and thinner than conventional lenses, making them appropriate for people with a high prescription.

Polarized lenses

Polarized lenses are a type of eyeglass lens that minimizes glare. Polarisation can be incorporated into the lens material or applied as a coating on the lens.

Blue Light Blocking lenses

These have special lens coatings that filter out blue light wavelengths emitted by digital screens. It can help reduce eye strain, headaches and sleep disruption from prolonged screen use.

Sun Bifocals

Dual-purpose lenses with distance and reading prescriptions combined. The top is for seeing far away, while the bottom segment magnifies for reading up close in bright sunlight.

Multifocal lenses

Advanced multifocal lenses provide a gradual transition between distance, intermediate and near vision zones, eliminating harsh lines. Great for all-day wear.

Polarized lenses

Lenses with a special filter that blocks intense reflected glare from surfaces like water, snow or glass. Enhances visual clarity and reduces squinting in bright conditions.

Eyeglasses Lens Coating Types

Lens coatings are microscopic layers applied to eyeglass lenses to improve vision and protect your eyes. There are several types:

Anti-Reflective Coating

Reduces glare from lights and screens for sharper vision. Great for driving at night or working on computers.
