This article focuses on the use of eye instruments in ophthalmology. It also highlights the role of visual aids in the upgraded vision care services. A literature review with a range of ophthalmic instruments used in ophthalmology is performed; the instruments’ efficacies and limitations are discussed, as well as their ethical and moral contribution to improved patient outcomes. The methods in the review are not limited to the systematic search of electronic databases and the analysis of peer-reviewed articles but also include the synthesis of relevant findings. This information brings out the optical instruments of those times, which were badly equipped, as evident from the figures, tables, and graphs to illustrate the important points. In the following conversation, focus on clinical practice matters, difficulties, and further directions, which lead to the conclusion that we must be sure that optical technologies will be incorporated into vision care delivery. The main suggestions are as follows: how to increase the benefits of an optical system to get the best possible results for patient care.
