Welcome to the forum!
Senegals are great little chams.
I agree with Ferrah88 that getting rid of the night bulb is important, for the reasons mentioned.
Much of your care is very good but there are just a few things you can do to ensure she stays healthy.
Chams can develop vitamin deficiencies unless their feeder insects are fed a good diet and the insects are dusted with 2 other supplement powders--in addition to the calcium without D3 that you already use.
A good schedule is typically
Calcium without d3 every feeding like this one

Calcium with d3 twice a month like this

A multivitamin twice a month like this one

Your chameleon needs a variety of feeder insects to stay healthy.
Different insects are higher/lower in various nutrients, so variety helps to prevent a vitamin/mineral deficiency.
In addition to the crickets, dubias, silkworms, hornworms, phoenixworms and blue bottle flies are all good.
This place carries a good variety of feeders:

It is also important to feed your feeder insects nutritious food because they are what your cham gets his nutrition from.
Here is a very good writeup about these 2 things by a vet and cham keeper:

I don't know if your cham has a UVB bulb but it is extremely important for her to have one so that she can utilize the calcium she takes in.
Many people here use this particular bulb because it provides enough UVB without overdoing it, which can lead to eye problems:

The bulbs need to be replaced every 6 months because even though they will still light up, the amount of UVB they put out keeps decreasing. All UVB bulbs need to be replaced at regular intervals, not just this particular one.
Your cham has been getting UVB from being outdoors when the weather was warmer. Indoors, the sunlight passing through the glass windows contains no UVB because it gets converted into heat, instead.
If she can't absorb the calcium, she will develop MBD--a serious health problem.
Details of that are here:

The yellow tinge to your cham's urates means that she needs a bit more water. Home heating systems tend to dry the air far more than we realize, so the mistings that kept her hydrated during the warmer months should be more frequent or longer lasting to her remain well hydrated.
Some people here have gotten humidifiers to help keep the indoors a bit more humid for the winter.
I bought a cool mist humidifer recently to benefit my family and it helps my chams, too.
Eye issues are fairly common cham troubles and can be caused by any of several things:
1) Infection, which can be due to injury, environmental issues, nutritional deficiencies or parasite problems
2) Malnutrition which can be caused by failing to gutload feeders or failure to feed a varied diet, improper supplementation, parasites or simply a higher need for a particular nutrient in an individual chameleon
3) Irritation--sometimes a cham's eye is irritated by something in their environment, such as too little humidity, sap from a plant or a bit of something getting into the eye (shed skin, soil particle, etc.) or even a bulb that emits too much UVB.
I suggest making the few dietary and other changes she needs and keeping a close watch on her eye, in case it is an infection.
A gentle rinsing of her eye with a sterile saline solution made for eyes can sometimes prevent an infection from taking hold, if done early on.
Once the eye is actually infected, it typically requires the services of a good, reptile-knowledgeable vet to determine the cause and prescribe the right antibiotics to cure it.
You can easily treat a vitamin A deficiency at home but it is extremely important to not give too much vitamin A.
A very tiny drop of cod liver oil from cod liver oil capsules (the ones sold for people to take) can be put on the back of a feeder that you give to your cham and should correct the problem within one or 2 days.
Giving more cod liver oil or giving it more often often is NOT better and will actually cause serious health problems (liver/kidney damage).
It is a good idea to find a vet with plenty of reptile knowledge, before you absolutely need one.
