The "8th International Conference on Eye and Vision" will take place in Paris, France, on April 21 and 22, 2023. Its purpose is to bring together cutting-edge academics and business specialists in the field of vision and the eye.

A general layman perception about eye testing is that it is only for checking the power of the glasses we need. However, there is much more to a full eye examination than visual acuity tests. Visual acuity tests involve the assessment of reading capacity of eyes from a given distance. The patient is asked to read out the fonts of different sizes, while covering one eye at a time, and with both eyes open. Based on how conveniently one can read the alphabets and characters, the optometrist keeps changing the lens combinations until appropriate power is identified. This is the most basic and manual method of evaluating visual acuity, which is also often practiced by non-specialists and opticians locally. Ophthalmologists also supplement it with a machine test for approximation of eye power. It is always performed by a qualified optometrist or ophthalmologist. They look for any underlying symptoms or conditions such as retinal detachment, glaucoma, development of cataracts, and macular degeneration.
