A Florida window tint exemption allows individuals with qualifying medical conditions to install window tint darker than the standard legal limits. This is especially helpful for those who suffer from light sensitivity, autoimmune diseases such as lupus, or other conditions aggravated by sun exposure. With an approved exemption, your darker window tint becomes legally recognized by the state—protecting both your health and your compliance with Florida law.
The exemption qualification process involves two parts:
While a medical exemption does allow for darker-than-legal tint, it does not mean unlimited darkness. The physician must determine the appropriate level of tint based on your condition, and the Florida DMV ultimately reviews and approves the recommendation. Once granted, your exemption allows for darker tint within medically justified limits.
ForeverTint can help make this process simple by connecting you with an independent licensed physician who reviews your medical history and, if you qualify, provides your completed and signed Form HSMV 83390 with clear instructions for submitting it to the FLHSMV.
Whether or not you plan to get a medical tint exemption, it’s important to understand Florida’s window tint laws. The state has strict guidelines that regulate how dark you can tint each window on your vehicle. These laws are enforced by the Florida Highway Patrol and outlined by the Florida Department of Highway Safety and Motor Vehicles (FLHSMV). They are designed to balance driver comfort with road safety, visibility, and law enforcement needs.
If you need darker-than-standard window tint in Florida especially on your front side windows or windshield—you’ll need a valid medical tint exemption. ForeverTint can help you find out if you qualify. Eligibility is determined by a licensed physician based on your medical history, and the FLHSMV makes the final decision on your exemption.
Traditionally, getting a tint exemption in Florida meant making an in-person doctor’s appointment, explaining your condition, and handling paperwork yourself. ForeverTint streamlines this entire process online:

Florida law provides a medical window tint exemption for individuals whose health may be negatively impacted by exposure to sunlight. This includes conditions that cause increased sensitivity to ultraviolet (UV) light, visible light, or heat. Below are conditions a physician may consider:
Lupus is an autoimmune disease in which ultraviolet light can trigger skin rashes, joint pain, and fatigue. Physicians commonly advise people with lupus to limit UV exposure, including the UVA light that passes through car side windows.
Porphyrias are a group of disorders in which certain compounds build up in the body and react to light, causing blistering, burning pain, and skin damage after sun exposure. Avoiding sunlight is a central part of managing the cutaneous forms.
Xeroderma pigmentosum is a rare genetic disorder that prevents the body from repairing DNA damage caused by ultraviolet light. People with XP burn after minimal sun exposure and face a greatly increased risk of skin cancers and eye damage.
People with albinism produce little or no melanin, the pigment that helps protect skin and eyes from ultraviolet light. They are highly prone to sunburn and skin damage and often experience significant light sensitivity and glare.
Photosensitivity dermatitis is an abnormal skin reaction to sunlight that can cause redness, itching, swelling, and rash on exposed skin. It can be linked to an underlying condition or to medications, and limiting UV exposure helps prevent flare-ups.
A personal history of melanoma or other skin cancers means ongoing UV exposure is a serious concern. Dermatologists routinely advise these patients to reduce sun exposure wherever possible, including time spent driving.
Some eye conditions, such as uveitis, certain retinal disorders, and sensitivity following eye surgery, cause pain or impaired vision in bright light. A licensed physician or optometrist can assess whether reducing light exposure while driving is medically necessary.
Cockayne syndrome is a rare genetic disorder that causes extreme sensitivity to sunlight, along with other developmental and health effects. Strict sun protection is part of everyday care.
Bloom syndrome is a rare inherited disorder that causes sun-sensitive skin, often with a facial rash after sun exposure, and an increased lifetime risk of cancer. Limiting UV exposure is a standard precaution.
Vitiligo causes patches of skin to lose their pigment, leaving those areas without natural protection from ultraviolet light. Depigmented skin burns easily, so physicians often recommend extra sun protection.
Some autoimmune conditions, such as dermatomyositis, cause skin and muscle symptoms that worsen with sun exposure. Certain medications used to treat autoimmune disease can also increase sensitivity to light.
Healing burns, skin grafts, and scar tissue are more vulnerable to sun damage, and UV exposure can cause scars to darken. Physicians typically advise protecting these areas from direct sunlight.
Other diagnosed conditions, including sun sensitivity caused by medications, can make sun exposure a health concern. Describe your condition during intake, and an independent licensed physician will review your medical history and decide whether darker tint is medically necessary for you.
To be valid, the Florida window tint exemption form must be:
Completed and signed by a licensed physician or optometrist
Include the physician’s full name, contact information, and medical license number
State the specific medical reason the patient requires darker tint
Clearly indicate whether the exemption is temporary or permanent
Include the patient’s full name and date the form was issued
Keep the medical exemption certificate issued by the FLHSMV in your vehicle at all times. If you are stopped by law enforcement, presenting it shows that the state has approved your exemption; officers still retain discretion.
Verbal explanations or handwritten notes are not accepted as proof. The certificate the FLHSMV issues is tied to the vehicle listed on it and becomes void if that vehicle is sold or transferred.

Florida allows a medical window tint exemption for people with a health condition that requires limited exposure to sunlight or UV light. Examples include lupus and other autoimmune diseases, albinism, and photosensitivity disorders. A licensed physician must verify that your condition requires darker-than-standard tint, and ForeverTint connects you with an independent licensed physician who reviews your medical history and determines eligibility.
Form HSMV 83390 must be completed and signed by a licensed physician or optometrist. Through ForeverTint, an independent licensed physician reviews your medical history and, if you qualify, provides your completed and signed form. You then submit it to the FLHSMV, which issues your medical exemption certificate. Keep the certificate in your vehicle at all times.
Yes. The state does not offer an online application, but you can start the process online through ForeverTint. An independent licensed physician reviews your medical history from the comfort of your home and, if you qualify, provides your signed form along with instructions for submitting it to the state. This saves you an in-person appointment and helps make sure the physician portion of your form is completed correctly.
Conditions that make a person sensitive to sunlight, UV rays, or visible light are typically considered, such as lupus and other autoimmune diseases, melanoma, photosensitivity disorders, and other dermatological conditions. An independent licensed physician makes the medical determination based on your symptoms and health history, and the FLHSMV makes the final decision on your exemption.
With a valid medical exemption, Florida allows window tint darker than the standard legal limits, including on the front side windows and windshield. The exact darkness level is not defined in the statute and should be reasonably necessary for your medical condition. Your physician will indicate what is medically appropriate, and the certificate issued by the FLHSMV is what you keep in your vehicle.
If you are pulled over, present the medical exemption certificate issued by the FLHSMV for your vehicle. A medical exemption does not guarantee you will not be stopped or cited; officers retain discretion. ForeverTint’s role is to help make sure the physician portion of your Form HSMV 83390 includes the details the state requires.
Renewal depends on the certificate the FLHSMV issues and on whether your physician indicates your condition is temporary or permanent. Your certificate is also tied to the vehicle listed on it and becomes void if you sell or transfer that vehicle. If you need new documentation, an independent licensed physician can review your history again.
