A LED lamp includes a number of lenses each of which includes a light emitting surface and a plurality of shades mounted on the light emitting surface. Each of the shades includes a hole whose sectional area in radial direction is equal to that of the light emitting surface. An axial height of the hole follows the formula H φ = ϕ ⁢ max tan ⁢ ⁢ θ max , wherein Hφ is the axial height of the hole, φmax is a diameter value of the light emitting surface, and θmax is an output angle of the lens. Accordingly, a work area of the anti-glare LED lamp can be extend the most thereof since the shades block the stray light of a glare area of the LED lamp and strictly separates the work area from the glare area, and no stray light shot into eye in any areas. Therefore, the anti-glare LED lamp can achieve light distribution as designed without glare under cooperation of the lenses and the shades.
