If the sclera contact lens does not fit, it may be due to a variety of reasons such as incorrect sizing, improper insertion technique, or an underlying eye condition. It is important to consult with an eye care professional to determine the exact reason for the poor fit and to explore alternative options. Wearing ill-fitting contact lenses can lead to discomfort, irritation, and potential damage to the eyes, so it is crucial to address any issues promptly. **

Sclera contact lenses are more expensive than regular contact lenses because they are larger and cover a larger portion of the eye. They are also custom-made to fit the unique shape of each individual's eye, which adds to the cost. Additionally, the materials used to make sclera lenses are specialized and often more durable, which contributes to the higher price. Finally, the process of fitting and designing sclera lenses requires more time and expertise from eye care professionals, further increasing the overall cost. **

An atomic defense shield is a theoretical concept that involves using advanced technology to protect against nuclear attacks. While there is no physical representation of an atomic defense shield, it would likely involve a combination of missile defense systems, advanced radar and early warning systems, and possibly even space-based weapons. The shield would need to be able to detect and intercept incoming nuclear missiles, as well as provide protection for key infrastructure and population centers. Overall, an atomic defense shield would be a complex and sophisticated network of defensive capabilities designed to deter and defend against nuclear threats. **

A nuclear defense shield typically consists of a network of anti-ballistic missile systems designed to intercept and destroy incoming nuclear missiles before they reach their intended targets. These systems can include ground-based interceptors, sea-based interceptors on ships, and space-based interceptors. The shield may also incorporate early warning systems, radar systems, and command and control centers to detect and track incoming threats. Overall, a nuclear defense shield is a complex and sophisticated system aimed at protecting a country from nuclear attacks. **
