Amblyopia, also known as lazy eye, is one of the most common causes of visual impairment, affecting nearly 3 percent of the population. It occurs when the brain does not process input from one eye properly, causing the weaker eye to be suppressed by the stronger one. As a result, the affected eye does not receive clear images and cannot focus properly.
Traditional treatment often involves patching the stronger eye to force the weaker one to work harder. However, this method is usually effective only in children.
Lazy Eye Games take a different approach by sending information to both eyes, encouraging them to work together. This cooperation helps the amblyopic brain relearn proper image processing by increasing brain plasticity.
Studies show that patients who played the games with both eyes open saw significant improvement in the vision of their weaker eye after just two weeks.
Those who used patching also improved, but their progress increased substantially when they switched to dichoptic (both-eye) training.
Lazy Eye Games are designed for people with amblyopia, including adults.
Tip: In each game, you can adjust colors for specific elements (e.g., falling and landed blocks in Lazy Eye Blocks). The goal is for each eye to see only its assigned color. This teaches your brain to use both eyes together.

(specifically versions like 5.20 ) is a specialized software utility used to view and modify Desktop Management Interface (DMI) and SMBIOS information directly within a computer's BIOS . It is primarily developed for systems using AMI (American Megatrends) BIOS . Core Functionality
DMI stands for , a standard framework for managing and tracking components in a desktop, notebook, or server computer. It is part of the SMBIOS specification. DMIEdit (and its command-line counterpart, AMIDEDi or AMIDEWIN ) acts as an interface that allows users to write new data to these specific fields. Note: For the most up-to-date tools, it is
"dmiedit+520" represents a potentially customized or extended version of a standard system information tool. Its exact features and use cases would depend on its specific design and implementation. For comprehensive and accurate guidance, referring to the tool's official documentation or support channels is essential.
Before making any changes, you must back up your current BIOS. If possible, also save your current DMI/SMBIOS data using the Save All feature in the File menu. This is your only lifeline to revert changes. You should also disable Secure Boot and Fast Boot in your BIOS to ensure the tool can write changes freely.
Last updated: October 2025 – dmiedit+520 confirmed working on AMI UEFI version 5.20 to 5.24 on Intel 100/200/300 series chipsets. The variant stands out from older versions (like v2
Correcting or changing system info for IT inventory tracking or spoofing purposes.
The 5.20 update is particularly significant because it ensures compatibility with newer standards. It provides a more stable interface for interacting with modern chipsets and Windows 10/11 environments, where older versions might fail due to security permissions or architectural shifts. Common Use Cases 1. System Branding and OEM Customization
However, its power comes with significant risk. If you simply want to change your boot logo or tweak fan curves, there are safer tools (e.g., AMIBCP, UEFITool). Only use dmiedit+520 when you have a clear, legitimate need, a full BIOS backup, and a recovery plan.
