If your eye floaters and flashes are caused by a retinal detachment or retinal tear, you may require urgent treatment. A retinal tear can usually be treated with a laser. This treatment is called laser retinopexy. We treat retinal detachment with surgery – the type of surgery depends on various factors, including size, duration and location of the detachment.

If you are experiencing eye floaters or flashes of light, book an appointment to discover the cause of your symptoms. Our specialists will provide a thorough consultation and perform any necessary tests.

Flashing lights are more common if you suffer from migraines and are usually associated with headaches. If you only see flashing lights, you may want to speak to your doctor before speaking to an eye specialist. You should also speak to a doctor if you have blurred vision or dizziness.

At your appointment, our specialist will ask about your symptoms to see how long and often you’ve had them. We will also examine your eyes to check for eye floaters and check for any signs of more serious causes. We may recommend further tests to rule out or diagnose an underlying cause. Then, we will discuss our findings with you and recommend treatment options where required.

Eye floaters and flashes of light are likely to increase as you age and are completely normal. However, there are circumstances when you should get these checked by a specialist.

Examine the plot of a cosine curve to the right. Notice that when the angle is zero, the cosine of zero is 1.0. As the angle increases, the cosine of the angle curves to zero. When the angle is 90 degrees, the cosine of 90 is 0.0. This is lambert’s cosine law. The cosine values are treated as percentages of color. When the angle is zero, cos(0) is 1.0, and you get 100% color. When the angle is 90 degrees, cos(90) is zero and you get 0% color. When the angle becomes greater than 90 or less than -90 the cosine goes negative. This is an indication that the front side of the triangle is pointing away from the light source. You can’t have a negative percentage of light, so we clamp the cosine of the angle to values between 0.0 and 1.0.

If both v0 and v1 are normal vectors that have a length of 1, the dot product gives the cosine of the angle without any division.

Do you see small dots, squiggly lines, rings or cobweb-like shapes drifting across your vision? We call these eye floaters. They will still be there if you blink, though they may become easy to ignore. Floaters may look black or grey, like a shadow.

Have you experienced dark shapes or frequent flashes of light over your vision? Book a private appointment to receive an expert opinion on your eye health.

“The whole experience was so easy, felt extremely relaxed before during and after surgery, excellent treatment, kept informed during the process, no discomfort at all.”

Light that directly strikes an object and then reflects in all directions is called “diffuse” light. The amount of light reflection is determined by the angle between the light ray and the surface normal vector. In Physics, Lambert’s cosine law provides an equation for calculating diffuse color.

Flashes are brief flashes of light, similar to camera flashes, over your vision. They are sometimes mistaken for a streak of lightning. You may experience floaters alongside flashes of light or separately.

As discussed, age is the biggest risk factor for floaters and flashes of light. You are more likely to experience floaters if you are over 50, are nearsighted (myopia), or have diabetes. Blood in your eye can also lead to experiencing them. This is less common, though you are more likely to experience this if you have diabetes, sickle cell disease or some other type of retinal disease.

The diagram to the right labels the pieces needed to calculate diffuse reflection. We need to calculate the angle between the vertex’s normal vector and a vector pointing at the light source from the vertex. This angle is labeled “theta” in the diagram.

If you are experiencing eye floaters, you should get your eye checked regularly to monitor your vitreous and prevent severe eye problems later on. We can remove them surgically, though this is not usually necessary. Moving your eyes by looking up and down or left and right can help shift the floater to a less disturbing position.

The dot product of two vectors is defined as the sum of the products of their associated terms. 3D vectors are normally stored as arrays, where (v[0], v[1], v[2]) is the values of the vector. Therefore, the dot product of vectors v0 and v1 is:

The example WebGL program above was based on a “point light source”. If you had a different type of light source, such as a sun light source, the shader programs would have to be changed because the definition of your light source would change, but the fundamental math would be the same.

It can be shown that the dot product of two vectors is equal to the cosine of the angle between the two vectors divided by the length of the two vectors. In code format, this means that:

The most common cause of eye floaters is age. The vitreous (a gel-like substance inside your eye) shrinks and becomes more watery as you age. As this happens, the vitreous pulls away from the eyeball’s inside surface (posterior vitreous detachment), which can cause flashes in the corner of your eye. The vitreous clumps and moves around in the eye as it is more mobile, seen as floaters.

The vitreous gel bumping or tugging against the retina of your eye can cause flashes of light. Persistent flashing lights with more floaters can be a sign of a retinal tear or retinal detachment, which can lead to permanent vision loss if left untreated. It’s hard to know the cause yourself, so you should seek the advice of an eye care specialist.

To perform diffuse lighting calculations each vertex that defines a triangle must have an associated normal vector. The normal vector defines a direction that is projecting out from the front side of the triangle. The normal vector defines how light will reflect off of a surface defined at the vertex. The normal vector may be 90 degrees to the surface of the triangle, or it might be at some other angle to simulate a curved surface.
