Colourblindness makes many everyday tasks difficult—such as recognizing traffic signals, selecting clothes, or interpreting colour-coded information. For those affected, even simple activities can become challenging.

At present, there is no permanent treatment available for colourblindness. However, ophthalmologists can play an important role in improving patients’ daily lives by recommending effective visual aids. With recent advances, several options are now within easy reach. Mobile applications can instantly identify and label colours, while specially designed glasses can enhance colour perception, particularly in red-green colourblindness.

This short write-up highlights sixpractical aids—both apps and glasses—with links for direct access. By guiding patients to these resources, ophthalmologists can help them adapt better and manage their condition with greater confidence.

Practical Suggestions for Use of Colourblind Apps and Glasses

• Start with Apps: Recommend patients begin using apps like Color Blind Pal or ColorADD for immediate, cost-free support in daily activities like shopping, matching clothes, and colour identification. These apps are easy to learn and carry on smartphones.
• Trial Glasses When Possible: For patients interested in optical aids, suggest a trial period with Pilestone or EnChroma glasses to evaluate personal benefit before full purchase, as impact varies individually.
• Combine Tools: Many patients benefit from using apps and glasses in combination — apps can help in situations where glasses have limited effect, especially indoors or in dim light.
• Consider Patient Lifestyle: Tailor recommendations based on patient profession, hobbies, and environment. For example, pilots or drivers might require specialized advice.
• Educate and Support: Provide clear instructions on app usage and care for glasses, and encourage regular follow-ups to assess effectiveness.
• Local Availability: Highlight brands and apps with good availability and support within India for cost-effectiveness and convenience.
