LED lights are generally considered safe for the eyes, especially if you choose warmer colored light over cooler ones. When it comes to lighting, a warmer color temperature is better for your overall eye health, especially if you spend many hours per day working at a desk.
But while both LED and incandescent lights produce some blue light which is linked to various eye problems (blurry vision, eye strain, etc.), it's important to note that LEDs do indeed produce more light in the blue spectrum. For this reason, LEDs are not recommended for overall room lighting but they're fine for desk lamps.
