In analyzing the UK's forecasted import of spectacle lenses of glass from 2024 to 2028, a gradual decline is observed from $13.45 million in 2024 to $13.017 million in 2028. Comparing this to the previous years' figures and assuming 2023 had a similar value as 2024, this suggests a steady, slight year-on-year decrease predicted throughout this period. Although specific variations for 2023 are not provided, a consistent decline highlights a notable trend.

Future trends to watch for include:

Technological advancements in eyewear alternatives potentially impacting glass lens demand.
Changes in consumer behavior towards sustainability and potentially preferring newer, environmentally friendly materials.
Economic factors, such as changes in trade policies and exchange rates, which may influence import costs and demand.
