LASIK vs Glasses vs
Contact Lenses

Three options for correcting myopia, hyperopia or astigmatism to each with genuine trade-offs. The right choice depends on your prescription, your cornea, your lifestyle, and what you are willing to accept long-term. This is the comparison your optician is unlikely to give you, because two of the three options are not things they sell.

The options side by side

What each option actually involves

Rather than a table of features, here is an honest look at what each correction method means in daily life.

Surgical correction

LASIK / SMILE

One-time procedure, lasting correction
No spectacles or lenses needed for most activities
Freedom for sport, swimming, travel, sleep
Fewer ongoing replacements than glasses or contact lenses over time
Requires a suitable cornea to not everyone qualifies
Reading glasses still needed after age 40 (presbyopia)
Requires a bigger initial commitment than spectacles
Temporary dry eye in the weeks after surgery
Optical aid

Spectacles (Glasses)

No surgery required, available to everyone
Easily updated as prescription changes
Provides UV protection and blue-light filtering options
Fog up, slip, break to physical inconvenience
High prescriptions create lens distortion at edges
Requires repeat purchases over a lifetime as prescriptions change
Limiting for sport, rain, physical work
Optical aid

Contact Lenses

No frames to natural field of view, aesthetics
Good for sport and active lifestyles compared to glasses
Toric lenses correct astigmatism effectively
Daily insertion and removal to discipline required
Infection risk if hygiene protocols not followed
Not suitable for dry eye sufferers
Requires monthly replacement, not a permanent solution
Cannot be worn while swimming or sleeping safely

Who qualifies for LASIK

Not everyone is a LASIK candidate to and that is important

One of the most common mistakes patients make is assuming that because LASIK is widely available, everyone can have it. The screening examination before the procedure exists specifically to identify patients for whom LASIK would be unsafe or ineffective.

The key requirements are: a stable prescription for at least one to two years, sufficient corneal thickness for safe tissue removal, no signs of keratoconus or irregular corneal topography, no active dry eye disease, and an age of at least 18 to 21 years. Patients with certain corneal conditions may be better served by SMILE vision correction, which does not create a corneal flap and carries lower dry eye risk post-operatively.

Stable prescription (≥1 year)

If your power is still changing, LASIK now means a second procedure later.

Adequate corneal thickness

The cornea must have enough tissue for safe ablation with a healthy residual bed.

Normal corneal topography

Irregular or cone-shaped corneas rule out LASIK. Keratoconus requires a different treatment path entirely.

Clinical perspective

What patients from Perambur
actually choose to and why

The question I am most often asked at Aadithya Eye Care is some version of "is LASIK worth it?" and the honest answer is that it depends entirely on what the person values. For a young professional who wears minus six dioptre glasses and has been doing so since school, spectacle freedom genuinely changes daily experience in meaningful ways. For someone whose prescription is mild, the difference is smaller.

What I do tell every patient considering LASIK is this: the decision should not be based on cost alone, and it should not be rushed. The pre-operative screening tells us whether your cornea is suitable. The conversation with you tells us whether your expectations are realistic. Patients who come in wanting LASIK but have thin corneas or irregular topography leave with a different option to sometimes SMILE, sometimes contact lenses are genuinely better for them long-term.

Contact lenses are a perfectly valid choice, but patients who use them for years often develop chronic dry eye symptoms from the reduced oxygen permeability and physical irritation. This is worth knowing. Several patients who come to us for a dry eye consultation find that the contact lens habit is the primary contributor.

Common questions

LASIK, glasses, contacts to
questions answered

LASIK permanently reshapes the cornea and the correction itself does not regress. However, if the prescription was still changing at the time of surgery, the underlying myopia progression can continue. This is why LASIK is recommended only when the prescription has been stable for at least one to two years. Most adults who have LASIK at the right time remain spectacle-free for decades. The very small proportion who need an enhancement procedure typically have very high prescriptions close to the upper limit of what is treatable.
Patients with thin corneas, keratoconus or other irregular corneal conditions, unstable prescriptions, severe dry eye, or prescriptions outside the safe treatable range are not suitable for LASIK. Some of these patients may still be candidates for SMILE (which removes a disc of tissue through a small opening without a flap) or for ICL (implantable contact lens). Others are genuinely better served by high-quality spectacles. An honest pre-operative assessment tells you clearly which category you fall into. Read more about LASIK candidacy at Aadithya Eye Care.
LASIK creates a flap in the outer corneal layer to treat the tissue underneath, then replaces the flap. SMILE removes a small disc of corneal tissue through a tiny keyhole incision without creating a flap. SMILE has a lower dry eye incidence post-operatively and avoids flap-related risks entirely, making it preferable for patients in contact sports or those already prone to dry eye. Both achieve comparable vision correction outcomes. Learn more about SMILE at Aadithya Eye Care.
Contact lenses used correctly and with proper hygiene are safe for most patients. The long-term issues arise from extended wear beyond recommended hours, inadequate cleaning, swimming in lenses, and sleeping in them. These behaviours significantly raise the risk of corneal infection, some of which can be sight-threatening. Chronic daily contact lens use is also a significant contributing factor to dry eye syndrome. We manage dry eye in many contact lens users at our contact lens clinic.
