Colour Changing 5025 Blue Light Glasses with Orange CR39 Lenses and TR90 Frame

These glasses are designed as a practical accessory for environments with prolonged exposure to screens and artificial light. The core function centres on the orange-tinted CR39 plastic lenses, which are specified to filter blue light and provide UV resistance. This combination aims to reduce potential eye strain associated with digital device usage. The frame is made from TR90, a material commonly selected for eyewear due to its lightweight and flexible characteristics. With eleven distinct colour options for the frame, labelled C1 through C11, the product offers a degree of personalisation based on the user's style preference, while the core visual and protective function of the orange lenses remains consistent across all colour variants.

Features and Construction

The build of these glasses focuses on two key components: the lenses and the frame, each chosen for their stated functional and material properties.

Material and Build

The frame is constructed from TR90, a type of thermoplastic elastomer frequently used in the manufacture of spectacle frames. This material is recognised for offering a balance of strength and flexibility, which can contribute to a comfortable fit and resistance to daily wear. The lenses are made from CR39, a standard thermosetting plastic polymer in optics. This material serves as the substrate for the orange colouration and the applied coatings that provide the blue light filtering and UV resistant properties mentioned in the product information.

Size and Practical Fit

While specific measurements for lens width, bridge size, or arm length are not provided in the source material, the use of TR90 for the frame suggests a design that can offer a degree of adaptability and comfort for various face shapes due to the material's inherent flexibility. The product is presented as a complete, ready-to-wear pair of glasses, implying a standard fit intended for adult use. The eleven colour options (C1 to C11) allow the user to select a frame shade that suits their taste, though this choice does not alter the physical dimensions or the optical performance of the glasses.

Uses and Placement

These glasses are positioned as a tool for managing visual comfort in specific modern settings, from professional workspaces to home environments.

Event or Professional Use

In office settings or during long periods of computer-based work, the glasses' blue light filtering capability is the primary relevant feature. The orange tint of the CR39 lenses is intended to alter the colour temperature of incoming light, which may help in reducing glare and the potential for digital eye strain. The UV protection adds a layer of defence against harmful rays, which can be a consideration near windows or in brightly lit workplaces. The range of frame colours allows for a professional appearance that can align with personal or corporate style.

Everyday Home Use

For home use, such as watching television, browsing on tablets or smartphones, or gaming, these glasses serve a similar purpose. The lightweight TR90 frame is suited for extended wear during leisure activities. The UV protection is also beneficial for general outdoor use on overcast days or in shaded areas, though the orange tint may alter colour perception. The included colour box provides a straightforward storage solution to keep the glasses protected on a bedside table, desk, or in a bag when not in use.

Benefits and Buying Value

The value proposition of this product lies in its stated functional purpose, material choices, and the option for colour customisation, all presented as a complete package.

Reuse and Low Maintenance

As a durable accessory, the glasses are designed for repeated daily use. The CR39 lenses are a hard plastic resistant to scratches under normal handling, and the TR90 frame material is known for its resilience. Maintenance is minimal, primarily involving periodic cleaning of the lenses with a soft cloth to maintain clear vision. The robust construction of both frame and lenses suggests a product built for regular wear without the need for specialist care, supporting long-term use from a single purchase.

Why Choose This Product

This model offers a specific combination of features: orange CR39 lenses for blue light and UV filtering, coupled with a lightweight TR90 frame available in multiple colours. It provides a focused solution for users seeking eyewear to address screen-related eye comfort without complex fittings or prescriptions. The value is in the integration of these two stated material technologies into one accessible product. The package is complete, requiring no additional purchases to start using, and the colour choice adds a layer of personalisation not always available in basic functional eyewear.
