Using drugs to enhance the experience of scope viewing by dilating pupils is an area that should be approached with significant caution. Certain drugs can indeed dilate pupils, a condition known as mydriasis, which could theoretically allow more light to enter the eyes and potentially improve the ability to see dim or faint objects through scopes or telescopes. However, this is not a widely recommended or safe practice for several reasons:
Safety and Legal Issues: Many substances that cause pupil dilation are either illegal, have legal restrictions, or fall under controlled substances. Using them without a prescription or medical supervision can lead to legal consequences and health risks.
Unintended Side Effects: Drugs that dilate pupils, such as atropine or certain psychotropic substances, can cause a range of side effects beyond pupil dilation. These may include blurred vision, dry mouth, increased heart rate, sensitivity to light, disorientation, or more severe adverse effects depending on the substance.
Optical Considerations: While larger pupils allow more light to enter the eye, this can lead to a reduction in the depth of field, making it harder to focus on specific objects without other visual distractions. Additionally, overly dilated pupils can make the eyes more susceptible to glare and reduce overall visual acuity.
Long-term Impact: Frequent use of mydriatic drugs can harm eye health and overall well-being. Repeated or prolonged use could potentially lead to dependency or diminish natural pupil response over time.
Alternative Methods: There are safe and legal ways to enhance nighttime or low-light viewing through scopes. These can include using scopes with better light-gathering capabilities, observing from areas with minimal light pollution, and allowing adequate time for natural dark adaptation of the eyes.

In summary, while the idea of using drugs for pupil dilation to enhance scope viewing might seem intriguing, the potential risks and legal implications far outweigh any perceived benefits. Individuals interested in improving their scope viewing experience should consider safer and more scientifically supported methods.
