Principle: In order to see the details of a small object, it is necessary to move the object close to the eye, so as to increase the angle of view and form a larger image on the retina. But when the object is too close to the eye, it can not see clearly. In other words, to be aware of the truth, not only should the object have a large enough angle to the eye, but also should take the appropriate distance. \tObviously, for the eyes, these two requirements are mutually restrictive. If a convex lens is placed in front of the eyes, this problem can be solved. Convex lens is the simplest magnifying glass, which is a simple optical instrument to help the eyes observe small objects or details.\u003c\/p\u003e","brand":"O2INEW","offers":[{"title":"Default Title","offer_id":1592698175503,"sku":"O2I-4-175311216006","price":5450.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0929\/2582\/products\/s-l1200__11537_043cfc7c-e0ee-4cbf-a546-3935dc63730f.jpg?v=1680028797","url":"https:\/\/order2india.com\/products\/30x-optical-glass-lens-6led-full-metal-folding-linen-tester-loupe-magnifier","provider":"ORDER2INDIA SHOPPING","version":"1.0","type":"link"}
