An optical lens, in order from an object side to an image-forming side, includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The object-side surface of the first lens has an effective diameter Φ1. The image-side surface of the first lens has a curvature radius Rand an effective radius D. The object-side surface of the second lens has an effective diameter Φ2. The optical lens satisfies at least one of the following conditions: 0.2≤Φ2/Φ1, Φ2/Φ1≤0.65, 0.65≤D2/R2 and D2/R2≤1.2.
