2. Refractive error: such as myopia, astigmatism, hyperopia, etc., will affect the vision, which will lead to the inability to focus the eyes when looking at things, affecting the daily life and work, and need to undergo optometry to solve the problem.
3. Macular Degeneration: It may be related to heredity, chronic light damage and other factors, resulting in vision loss and blurred vision, which will lead to inability to focus the eyes when looking at things, and in severe cases, it may also cause blindness.
