Skylight Heat! HeatBlocker?

We purchased a home 3 years ago. The past owner had 2 Velux skylights installed in our living room. My wife loves the natural light but the heat kills me. Do you have any suggestions on how to diffuse the heat? I know blinds may work, but do you know of any other method? I have been looking up the product called HeatBlocker. It is a canvas type of material that you install outside on the roof over the skylight. It suppose to diffuse 80% of the heat? Has anyone ever used this before? I live in Wisconsin and we have the extremes of hot and cold with snow.

Thanks in advance for your suggestions!

One option is to install a glass sash at the ceiling level. It should be openable (hinged) to access the space inside for cleaning. I've seen this done in bathrooms to reduce condensation problems in cold weather.

I have installed blinds a couple dozen times for home owners and all were happy with the results.
With the blinds you can leave them open in colder temps to get the suns heat, than closed when warming.

The last ones I did were Velux, the set up 'material wise' was roughly $68.00 per 2' x 6' unit, smaller units will be a few bucks cheaper and they are a reasonably easy diy project.

Where did you purchase the Velux blinds? I have roughly 2x4 skylight and the cheapest I can find is $150.

Somebody may make a flexible sheet that reflects visible light/infrared light that sticks on the outside of the skylight glass.

The radiant energy of sunlight only causes heat when it is absorbed.
