The shades includes a flexible and soft frame that can be placed against the face of a jaundiced person. At least one light-absorbing filter capable of filtering phototherapy light to both eyes of the person is affixed to the frame. The light-absorbing filter is a light intensity reduction filter of the blue-to-yellow light or the blue light from the phototherapy light. Advantages of the phototherapy shades presented herein exist due to the ability of patients to see their surroundings during phototherapy and caregivers to observe newborn's state of alertness. ## Claims ### Claim 1 Phototherapy eye shades, comprising a frame sized to be wearable on a person's head, wherein said frame comprises at least one light-absorbing filter capable of filtering phototherapy light to both eyes of said person and wherein said light-absorbing filter is a light intensity reduction filter of the blue-to-yellow light or the blue light from said phototherapy light. ### Claim 2 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter filters wavelengths between 400 nm and 610 nm. ### Claim 3 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter transmits about 2% to 20% of said blue-to-yellow light or about 5% to 20% of said blue-to-yellow light. ### Claim 4 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter transmits wavelengths greater than 610 nm. ### Claim 5 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter transmits wavelengths greater than 610 nm, wherein said transmission is at least 80%. ### Claim 6 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter transmits about 2% to 20% of said blue light or about 5% to 20% of said blue light. ### Claim 7 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter transmits about 90% of the visible light other than said blue light. ### Claim 8 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said light-absorbing filter comprises a silver material, a gray material, a bronze material, a gold material, a polycarbonate, a polyester, a styrene, an elastomeric, a Roscolux material, a light reflecting material or a metalized polyester film. ### Claim 9 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said frame is a single piece of material or made of a stretchable material. ### Claim 10 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said frame fits around the head of said person. ### Claim 11 (depends on 1) The phototherapy eye shades as set forth in claim 1, wherein said frame is a one-size fits all children head sizes. ### Claim 12 A method of reducing phototherapy light exposure to the eyes of a jaundiced person during a phototherapy session, comprising the step of having said jaundiced person wear a frame during said phototherapy session, wherein said frame comprises at least one light-absorbing filter capable of filtering phototherapy light to both eyes of said person and wherein said light-absorbing filter is a light intensity reduction filter of the blue-to-yellow light or the blue light from said phototherapy light. ### Claim 13 (depends on 12) The method as set forth in claim 12, wherein said light-absorbing filter filters wavelengths between 400 nm and 610 nm. ### Claim 14 (depends on 12) The method as set forth in claim 12, wherein said light-absorbing filter transmits about 2% to 20% of said blue-to-yellow light or about 5% to 20% of said blue-to-yellow light. ### Claim 15 (depends on 12) The method as set forth in claim 12, wherein said light-absorbing filter transmits wavelengths greater than 610 nm. ### Claim 16 (depends on 12) The method as set forth in claim 12, wherein said light-absorbing filter transmits wavelengths greater than 610 nm, wherein said transmission is at least 80%. ### Claim 17 (depends on 12) The method as set forth in claim 12, wherein said light-absorbing filter transmits about 2% to 20% of said blue light or about 5% to 20% of said blue light. ### Claim 18 (depends on 12) The method as set forth in claim 12, wherein said light-absorbing filter transmits about 90% of the visible light other than said blue light.
