Research shows that red light therapy may be useful for relieving some types of pain, particularly pain due to inflammation (irritation and swelling of body tissues). A review of 11 studies looking at the effect of red light therapy on pain found mostly positive results, though the authors said that more studies are needed. In another small study, people with temporomandibular dysfunction (TMD) had less pain, clicking, and jaw tenderness after red light therapy.

A review of multiple studies found that red light therapy can be an effective treatment for androgenic alopecia, a genetic disorder that causes hair loss. Another review of 11 studies found similar promising results. In some studies, hair thickness improved as well as hair growth.

Some providers use red light therapy as a weight loss treatment. This is often called body contouring, or body sculpting. Red light therapy may help reduce the circumference of your body in the area that was treated, but the effect will likely be temporary and not due to any real weight loss.

Red light therapy is also sometimes called low-level laser therapy, low-power laser therapy, low-power laser, or photobiomodulation.

Research shows red light therapy may smooth your skin and help with wrinkles. Researchers think it does this by stimulating collagen production, which helps improve skin elasticity. Research shows it also helps improve signs of sun damage.

Microscope objective lenses are a classic example of optics in our lives. The function of the microscope is to enlarge objects our eyes cannot see. Unlike telescopes which enlarge far away objects, the sample observed by the microscope is close to the lens. Microscopes also correct aberration, which otherwise would lead to blurry images. Achromatic (doublet) lenses only correct for aberration of two wavelengths of light whereas apochromatic (triplet) lenses correct for 3 or more wavelengths.

If you don’t want to use an at-home red light device, you can get red light therapy at a variety of places, including a doctor’s office or a spa. If you want to see a doctor to do red light therapy, you will likely see a dermatologist, a doctor who specializes in treating the skin. At a clinic or a spa, you may see an aesthetician — a licensed skin care professional.

Red light therapy is a noninvasive treatment that may help with several health conditions including wrinkles, acne, hair loss, rheumatoid arthritis, and other conditions that are still being investigated. You can do red light therapy at home using devices including masks and wands, but it may be more effective at a doctor’s office where the lights are more powerful. Though it can be expensive, it is generally considered to be safe.

People who take medications that increase their skin or eye sensitivity should not use red light therapy. People who have a history of skin cancer or eye disease should speak with their doctor before using red light therapy.

In red light therapy, you expose your skin to a lamp, device, or laser with a red light. It uses an LED (light-emitting diode) that emits the correct spectrum of light. Red LED light travels deeper into the skin than blue LED light, which is sometimes used to treat skin surface conditions such as acne. When the light enters your skin, your mitochondria soak it up and make more energy, which helps cells repair themselves.

The number of red light therapy treatments you need depends on what you are getting treatment for. But you will likely need ongoing sessions for weeks or even months.

One of the factors that go into designing an objective lens is the magnification. The colored bands on the outside of the microscope indicate the magnification of the lens. The standard magnification bands are as follows: red band = 5x, yellow = 10x, green = 20x, blue = 40-60x, white = 100x. Thus, if a lens has a green and yellow band, the magnification would be 30x.

Red light therapy uses very low levels of heat and doesn’t hurt or burn the skin. Unlike the light used in tanning booths, it doesn’t expose your skin to damaging UV rays.

Even at a doctor’s office, however, there are some risks. One early-stage clinical trial found that at high levels, red LED lights such as those used in red light therapy can cause blistering and redness on the skin. Red light therapy may also cause eye damage in some cases, so it is best to wear protective goggles when using a red light therapy device.

A review of studies found that red light therapy may be a helpful short-term treatment for pain and morning stiffness for patients with rheumatoid arthritis. However, it doesn’t seem to be very helpful for other forms of arthritis, such as osteoarthritis.

There is no evidence that red light therapy causes cancer. Red light therapy does not use ultraviolet rays, a form of radiation found in tanning booths and sunlight that can lead to skin cancer.

If you decide to use a red light therapy device at home, note that it may not be as powerful or effective as devices used by doctors or other professionals. When choosing an at-home device to purchase, you can check whether it has been cleared by the US FDA, which means that it is safe and equivalent to other devices already on the market. When using a red light therapy device at home, make sure to use proper eye protection and follow all directions on the device.

Tendinopathy is a condition that causes pain and loss of function in your tendons. A review of 17 clinical trials studying the impact of red light on treating tendinopathy found low-to-moderate quality evidence indicating that red light can help relieve pain or improve function.

Red light therapy appears to be mostly safe when used correctly, especially in the short term. Many forms of red light therapy are more effective when done at a doctor’s office rather than at home. That's because doctors can use stronger lights.

Red light therapy wand. These are handheld devices that have red LED lights at one end. You use them by moving the wand over your skin in the areas that you want to treat. They are used to treat very small areas, such as the back of the hands, one knee, or a particular spot on the face.

Red light therapy is a treatment that may help skin, muscle tissue, and other parts of your body heal. It uses low levels of red light to target your skin and cells. It is thought to work by increasing the production of mitochondria, your cells' energy sources. This may improve cell function and repair.

MicroscopeObjectives magnification

Another factor to consider in designing an objective lens is the working distance (WD). This is defined to be the distance from the front of the objective to the sample when in sharp focus. Working distance is related to the numerical aperture (NA) which is calculated by the formula NA = n * sin(θa), where n is the index of refraction. When in air, n = 1. To obtain a greater refractive index and increase the numerical aperture, sometimes the objective is immersed in a liquid such as oil or water. While aberration, magnification, working distance, and numerical aperture are not the only variables to consider when designing a microscope, they are key characteristics that one should look for.
