Adjusting to bifocals, trifocals, or progressive lenses can be challenging. Unlike traditional glasses, these versions include two or more vision zones. Because people use different parts of the lens for different tasks, objects can seem slightly distorted when they move their eyes.

Bifocals have two vision zones: the top helps with distance and the bottom for close viewing. Trifocals add a third zone in the middle for middle-distance tasks, such as computer work. Progressive lenses cover all distances, but with no lines in the lenses.

Poor night vision could be caused by an outdated eyeglass prescription or an eye condition, such as dry eye, cataracts, or age-related macular degeneration. People should see an eye care specialist for a complete eye exam to check for these issues.

Many activities, such as reading small print or doing needlework, contribute to eye strain. To avoid or reduce eye strain, it helps to keep eye surfaces moist and take breaks when doing anything that requires focused close-up vision.

As the number of pickleball players has grown, so has the number of eye injuries in people ages 50 or older, according to a 2025 study. Such injuries include damage to the eye surface, retinal detach­ment, or fractures near the eye socket.

Prescription eye drops, such as pilocarpine hydrochloride (Vuity, Qlosi) and aceclidine (VIZZ), can ease blurry close-up vision that occurs in middle and older age. The eye drops temporarily shrink the eye's pupil, which focuses light and makes near vision sharper. The eye drops are considered generally safe to use daily or occasionally, depending on preference. However, they can have side effects, such as dim vision and headaches. In rare cases, they might cause retinal problems.

Dry eye disease is broken down into two types: In aqueous-deficient dry eye, the eyes don't produce enough tears. In evaporative dry eye (sometimes called meibomian gland dysfunction) there are enough tears, but they're unstable and evaporate too quickly. Dry eye symptoms include eyes that feel gritty, sandy, stinging, burning, scratchy, tired, or sensitive to light. People with symptoms often forgo seeing a doctor. Artificial tears are an effective starting point for many cases of dry eye.
